62d0d3712e - use a sprite flag to mark mapped sprites. 
This avoids another global array which needs to be addressed by sprite index.
 2021-10-14 15:09:43 +02:00
Christoph Oelckers
83944a7191 - fixed uninitialized light index variable for floor sprites. 2021-10-11 22:28:26 +02:00
Christoph Oelckers
29769dd673 - fixed engine code warnings pointed out by XCode 13. 2021-10-08 19:06:41 +02:00
Christoph Oelckers
0d4e0d72fb - fixed vertex generation when splitting walls by planes on old hardware. 2021-09-18 13:04:46 +02:00
Christoph Oelckers
7f485bfab1 - split off the extended sprite flags into their own word. 
Some code overwrites the cstat field entirely (thanks Duke, for being sloppy with this...!)
 2021-09-12 18:26:35 +02:00
Christoph Oelckers
99ecfe133d - flag sprites for automapping regardless of the 'automapping' variable's value. 
Duke should show its floor sprites, too.
 2021-09-12 18:22:38 +02:00
Christoph Oelckers
0069af02e7 - use a slightly higher depth bias for translucent elements. 
These can otherwise cause z-fighting when being used with non-translucent floor and wall sprites.
 2021-06-13 09:39:07 +02:00
Christoph Oelckers
9d36e61d3f - depth bias fixes. 2021-06-09 00:47:13 +02:00
Christoph Oelckers
a32489be31 - wall sprite positioning tweaks. 
Turns out that a distance of one Build unit from a wall alone is not enough to render them glitch-free, some depth bias is still needed.
 2021-06-09 00:31:54 +02:00
Christoph Oelckers
f96521a7f4 - fixed: Floor sprites must set their view orientation. 
The translucent element sorter needs this to operate properly.
 2021-06-02 20:32:35 +02:00
Christoph Oelckers
3c5ef9c8e6 - properly render geometry that's fully shrouded in fog. 2021-06-01 21:48:39 +02:00
Christoph Oelckers
2e9732ce79 - fixed new renderer's use of fog on skies: The palette value from the wall was used instead of the one from the sky plane. 2021-05-29 12:09:16 +02:00
Christoph Oelckers
264d42179e - optimized the wall drawer a bit to avoid repeated calls to the render API's deoth bias function. 
The setters in FRenderState should check if the value actually changes and the wall drawer should only call it for non-translucent wall sprites.
 2021-05-21 19:07:22 +02:00
Christoph Oelckers
4bb57cfab5 - fixed flickering floor sprites. 
The SetDepthBias call was somehow gotten lost.
 2021-05-21 19:03:39 +02:00
Christoph Oelckers
f7a424cd06 - fixed precision issues with GetClosestPointOnWall for orthogonal lines. 
The math failed for some large wall sprites (e.g. Blood E2M4, sprite #181), and in orthogonal cases it is better anyway to perform direct checks of the coordinates
 2021-05-21 18:25:30 +02:00
Christoph Oelckers
24dbfc7827 - fixed BunchInFront to do a more thorough comparison in case it encounters colinear walls. 2021-05-21 14:32:01 +02:00
Christoph Oelckers
079a95a0a3 - use a higher depth bias for non-orthogonal wall sprites. 
Due to minor angular inaccuracies they are more sensitive to z-ordering than orthogonal ones when things are closely stacked.
 2021-05-21 14:32:01 +02:00
Christoph Oelckers
be97ee04f9 - re-enable flat sprite rendering. 
This was commented out for testing but forgotten afterward.
 2021-05-20 19:21:14 +02:00
Christoph Oelckers
5cfd810311 - new renderer: take fog properties for walls and ceilings from the proper elements. 2021-05-20 19:17:21 +02:00
Christoph Oelckers
b5358bc03c - fixed typo in wall sprite offsetting code. 2021-05-20 18:25:19 +02:00
Christoph Oelckers
d4eb54d686 - render free standing wall sprites without depth bias. 
Otherwise they can end up badly ordered with walls.
 2021-05-20 12:36:35 +02:00
Christoph Oelckers
5fd41ab910 - new renderer: draw the fog layer for skies. 
Code was active but alpha wasn't set.
 2021-05-18 00:42:45 +02:00
Christoph Oelckers
5e94eaff8e - new renderer: handle light level underflows. 2021-05-16 18:50:54 +02:00
Christoph Oelckers
a348508779 - handle the wall sprite clipping properly. 2021-05-16 16:00:00 +02:00
Christoph Oelckers
5bb438b817 - new renderer: fixed bad positioning when a y-flipped wall sprite had to be clipped to floor or ceiling. 2021-05-16 12:17:26 +02:00
Christoph Oelckers
845ce63348 - make sure that all objects rendered as shadow reset the object color after the draw call. 2021-05-15 10:40:25 +02:00
Christoph Oelckers
55abb261c6 - this was in the wrong place. :( 2021-05-15 10:25:37 +02:00
Christoph Oelckers
db8572dbcc - newrenderer: clip wall angles before doing any math with them. 
In some cases these unclipped ranges ended up in other data structures, causing problems with bunch ordering.
 2021-05-14 12:56:37 +02:00
Christoph Oelckers
3d6ae40bc0 - normalize all angles to the actual viewing range in the drawer. 
This simplifies the debugging of this code a lot because we no longer have to deal with range overflows and can do direct comparisons everywhere.
 2021-05-14 10:50:22 +02:00
Christoph Oelckers
cb2bc7967a - fixed the remaining warnings. 2021-05-12 21:50:01 +02:00
Christoph Oelckers
d097c8e635 - removed the non-functional and long abandoned level music alias feature. 
With RMAPINFO such a hack is no longer needed for anything.
 2021-05-12 21:48:40 +02:00
Christoph Oelckers
783b94f922 - more warning fixes in 'core'. 2021-05-12 21:48:14 +02:00
Christoph Oelckers
03289f5097 - silenced some warnings. 2021-05-12 21:47:32 +02:00
Christoph Oelckers
e74aca291c - position tweaking for Nam's skies. 
Why is this such an utter mess to get skies placed correctly? :(
 2021-05-10 20:13:28 +02:00
Christoph Oelckers
325af156e7 - fixed loop in ProcessBunch to account for array reallocation. 2021-05-08 09:16:06 +02:00
Christoph Oelckers
79823b430c - reinstate the old code for rendering the first portal without stencil 
The previous commit fixes the true issue causing the problems - with this back the restriction is not needed anymore.
 2021-05-07 00:26:22 +02:00
Christoph Oelckers
b644000b02 - fixed texture y-flipping on bottom tiers of walls. 
The flip flag was taken from the wrong side of the wall.
 2021-05-07 00:18:13 +02:00
Christoph Oelckers
29b0106a96 - fixed yet another problem with the local 'sprite' variables in HWWall causing problems. 
This variable and its companions in HWFlat and HWSprite have now been renamed to avoid these issues.
 2021-05-07 00:09:30 +02:00
Christoph Oelckers
d206a767b2 - added render workaround for CP07. 2021-05-03 17:48:35 +02:00
Christoph Oelckers
d8b808576f - restrict the sky portal shortcut to skies in scenes where there are no other portals. 
This entire setup does not work with sector portals, causing various render glitches in Shadow Warrior's portals. This also applies to skies within portals so it is now restricted to single sky setups.
 2021-05-03 14:52:23 +02:00
Christoph Oelckers
389340f97c - use sections for rendering. 2021-05-03 00:15:09 +02:00
Christoph Oelckers
aa6bd8ffcc - factor in angoff when placing sprites. 2021-04-25 11:58:03 +02:00
Christoph Oelckers
ad28630df6 - offloaded map patches to data files. 
This is a lot easier to manage than having them in the code.
For now it piggybacks on the map hack feature, later this should use the same scripted approach as GZDoom.
 2021-04-24 23:07:35 +02:00
Christoph Oelckers
a7046eaee4 - fixed animations on skies. 
Lunatic Fringe made this very obvious.
 2021-04-24 20:04:02 +02:00
Christoph Oelckers
5585351c0f - added a hack to help the new renderer with Lunatic Fringe. 
This is by no means a permanent solution but having it buys some time to find something more universal that won't affect performance too badly and investigate the need for a more robust solution.
The idea here is to define pairs of walls where when the first element of the pair is seen, it will treat the second one as view blocking.
This is used as the two offending windows (sectors 151 and 152) to cope with the lack of a height sensitive clipper.
 2021-04-24 20:00:54 +02:00
Christoph Oelckers
be08a2f800 - clipper rework 
* let the clipper work on relative angles to simplify the math.
* properly initialize the initial visible range and preserve it for multiple invocations.
* track the maximum visible angular range per sector. While possibly not sufficient to handle every edge case imaginable it has low overhead and is still useful to eliminate obvious cases that do not need more complex checks. It is enough to fix the blue door in Duke E3L4.
* removed unused elements of the clipper.

eb573bea23 - removed all compensation for the clamped shades. 
None of this is needed, the shader can work with out of range shades to produce proper lighting.
 2021-04-21 22:48:55 +02:00
Christoph Oelckers
dc0df7d081 - don't clamp shade values in the setup pass. 
We need their proper values when setting up the lighting.
 2021-04-21 22:32:27 +02:00
Christoph Oelckers
643b969dff - added another weird Build specialty: no vertical sprite offset flipping for face sprites. 
Just... why...? :?
 2021-04-20 19:37:32 +02:00
Christoph Oelckers
be20b6a839 - fixed: wall sprites do not need NPOT emulation. 2021-04-20 16:58:18 +02:00
Christoph Oelckers
d078b511b8 - flip backwards oriented wall sprites before submitting them to the render list. 
Backwards orientation will break the translucent object sorter so this needs to be sorted out beforehand.
 2021-04-20 14:30:22 +02:00
Christoph Oelckers
ccdf9d13f1 - do not render sprites that are extremely close to the camera. 
These can temorarily cover the entire screen so everything with a distance of less than 4 map units will now be skipped if it is a face sprite.
 2021-04-20 00:15:11 +02:00
Christoph Oelckers
cdf89b9175 - portal rendering fix when viewing through two-sided walls outside the actual portal area. 
If there's more portal area behind such a line its range in the clipper needs to be cleared again.
 2021-04-17 18:32:40 +02:00
Christoph Oelckers
2b1072eb91 - fixed bad sector addressing in flat sprites drawer. 2021-04-14 19:17:40 +02:00
Christoph Oelckers
5c306c61d6 - better fix for shadow rendering. 2021-04-14 14:46:15 +02:00
Christoph Oelckers
89be30b720 - handle fullbright sprite hackery using negative shade values. 2021-04-12 18:57:10 +02:00
Christoph Oelckers
bf019ac028 - Build must draw the sky for completely closed sectors as well. 2021-04-12 16:31:44 +02:00
Christoph Oelckers
ef95754e87 - fixed bad texture checks. 2021-04-11 18:38:26 +02:00

057b8a7354 - cleanup of bvectan family of functions. 
This can be greatly simplified to a single bvectangbam function using atan2 directly.
 2021-04-10 12:54:29 +02:00
Christoph Oelckers
35221188db - inlined Clipper::PointToAngle 2021-04-10 10:56:11 +02:00
Christoph Oelckers
2e191f2742 - consolidated the SetLightAndFog code fragments. 2021-04-10 10:34:20 +02:00
Mitchell Richters
28fb752446 - Replace gethiq16angle() with bvectangbam() in renderer code. This addresses some observed clipping issues in the new renderer. 2021-04-10 09:23:02 +10:00
Christoph Oelckers
e0dc261dfd - fixed edge case in wall sorter when the camera is exactly on a line that's being checked. 2021-04-10 00:05:29 +02:00
Christoph Oelckers
345275db5d - better handling for portal lines having sloped back sectors. 
This is a very ugly special case that probably needs a bit more work to get right, for now this should be enough as this combination is rather rare.
 2021-04-09 22:48:16 +02:00
Christoph Oelckers
c9483353ff - some more translucency checks. 2021-04-08 19:56:18 +02:00
Christoph Oelckers
1362a7ebc5 - added extended translucency support and did a bit of code consolidation. 2021-04-08 19:45:18 +02:00
Christoph Oelckers
38ecfc8fa5 - added handling for cubemapped skyboxes. 2021-04-08 12:47:31 +02:00
Christoph Oelckers
b68512ef88 - on closer inspection, do not draw skies on intra-sky lines ever - the renderer already takes care of this elsewhere. 2021-04-08 10:10:15 +02:00
Christoph Oelckers
d348377bd8 - when drawing skies on walls where both sides are sky, use the backside's texture. 
This fixes a sky anomaly in RR's E1L1.
 2021-04-08 09:45:17 +02:00
Christoph Oelckers
7a03967ceb - fixed clipping info not properly reset when rendering the scene in two passes. 
We need to reset the gotsector array for that, but since we also need the accumulate result of both passes there's now two such arrays.
 2021-04-07 16:52:17 +02:00
Christoph Oelckers
caa8efd3d5 - fixed renderer to avoid bunches of walls that wrap around behind the camera's back. 2021-04-07 16:09:25 +02:00
Christoph Oelckers
4bd44f9d62 - flat sprites use different visibility rules. 
Hooray, Build engine, yet another totally nonsensical magic factor with absolutely no reason why...
 2021-04-07 12:58:45 +02:00
Christoph Oelckers
6ad0089524 - fixed flat sprites using the sector bit names for checking for being flipped. 
Thank you, autocompletion... :(
 2021-04-07 12:39:12 +02:00
Christoph Oelckers
59f18f5fa7 - ensure that all HWSprites are oriented with z1 > z2. 
This is required by the sorting code to work as intended.
 2021-04-07 12:31:47 +02:00
Christoph Oelckers
f9f1d591b3 - must set up fog before textures. 
Otherwise the PickTexture callback won't get all needed info.
 2021-04-07 10:30:49 +02:00
Christoph Oelckers
3d846f341a - fixed a major clipping issue with the new renderer. 
* the bunch drawer can at most process an angular range of 180°. If this gets exceeded it can run into wraparound issues that may cause holes in the geometry.
* there was no clipping to the current field of view so it always checked the full 360°.
 2021-04-07 00:02:36 +02:00
Christoph Oelckers
d823ae255e - fixed view clipping for portal sectors. 
All lines within the portal must neither be added to the clipper nor checked for obstruction by other parts of the map.
 2021-04-06 19:25:40 +02:00
Christoph Oelckers
d193e199f1 - reorganized hightile offset storage. 2021-04-06 15:55:33 +02:00
Christoph Oelckers
16ad5f0cc8 - fixed sky rendering in palette emulation mode. 
The sky dome drawer cannot work with indexed textures, but since they are fullbright anyway we can just temporarily disable it.
 2021-04-05 21:53:19 +02:00
Christoph Oelckers
e30dc82676 - Cleanup of the voxel code. 
* moving polymost_voxdraw into polymost.cpp.
* consolidated all remaining voxel code in hw_voxels.cpp. All original Build voxel code is completely gone now, except for polymost_voxdraw, so this got moved out of the build/ folder.
* integrate Blood's voxel init code into the main function.
* some further cleanup was allowed as a result of this, so engineInit is gone now because these parts can now be done outside the games' app_init functions.
 2021-04-05 18:05:43 +02:00
Christoph Oelckers
de2df926e1 - fixed render timing. 2021-04-05 11:54:28 +02:00
Mitchell Richters
172e3996bb - HWSprite::Process(): Added x-off-by-one-fix for sprites similar to yspans from b7bad558da. 2021-04-05 19:37:00 +10:00
Christoph Oelckers
c303884274 - better handling for Duke's scrolling cloudy skies. 
* Using the Doom-style dome here because it looks better.
* this necessitated changes to the backend to allow both types of sky domes at the same time
* do not clamp panning fields for cloudy sky with the new renderer because this makes the texture jump.
 2021-04-04 20:35:38 +02:00
Christoph Oelckers
39c457bbf2 - removed a few unused CVARs carried over from GZDoom. 2021-04-04 19:35:12 +02:00
Christoph Oelckers
ea91b5ba5d - added a map patch for SW:WT's 'skyline' map. 
This contains a badly tagged sky sector that makes the new renderer glitch out.
 2021-04-04 18:57:03 +02:00
Christoph Oelckers
1201cc71ef - fixed voxel rendering. 
No, that 'while' was even pointless in Polymost, much more here where it runs within another loop.

Christoph Oelckers
d76c2ccc34 - voxel rotation. 2021-04-04 13:24:33 +02:00
Christoph Oelckers
d71ebace97 - fixed fog density of the new renderer. 
The actual value needs to be a lot lower than for Polymost due to the different projection.
 2021-04-03 22:51:31 +02:00
Christoph Oelckers
d7a13fc9f2 - same for the new renderer. 2021-04-03 21:40:32 +02:00
Christoph Oelckers
ab36b86a59 - sky tweaking 
* Build skies need a different mesh for the dome - the one from GZDoom distorts them too much.
* made adjustment to the positioning math after redoing the mesh
* Exhumed abuses some strange effect of the original sky placement math which means the y-offsetting must be disabled for this game.
* RRRA sky initialization fixed. It must be done after setting up the tiles.
 2021-04-03 21:06:02 +02:00
Christoph Oelckers
dc234ea72d - implemented RR's geometry effect. 
The grossest of all gross render hack that were ever done with Build...
 2021-04-02 22:52:46 +02:00
Christoph Oelckers
54eee347a6 - do y-flipping of wall textures correctly. 
1.f - h is not correct for NPOT texures due to hpw they tile.
 2021-04-02 22:50:53 +02:00
Christoph Oelckers
7446d0441b - use LGPLv2 for all Raze specific render code. 2021-04-02 18:22:54 +02:00
Christoph Oelckers
638f19172a - voxel rendering. 
The stock voxels of Blood and SW seem to work so far, but not all edge cases have been tested.
 2021-04-02 18:20:07 +02:00
Christoph Oelckers
c8a75a8664 - give each DrawInfo its own list of tsprites. 
Since these do not fully get processed sequentially the contents need to be preserved until needed.
This required getting rid of the global tsprite array. Polymost still uses a static vatiable, though, but this is only accessed in polymost-exclusive code.
 2021-04-02 10:28:40 +02:00
Christoph Oelckers
6afbb82e66 - fixed one-sided wall sprite checks. 2021-04-02 09:04:13 +02:00
Christoph Oelckers
80e5cd0dc5 - fixed some automap issues: 
* Blood's automap was not drawn at all.
* SW's automap always showed all sectors
* SW's player sprite was not rendered.
* Non-automap: Forward gotsector to the game code because there's still a few places in Blood that need it.

85020b374a - use texture clamping on non-tiled walls. 2021-04-01 19:21:24 +02:00
Christoph Oelckers
e1df17964e - fixed handling of SW's shadows. 
An out of range shade will only work without fog.
 2021-04-01 19:10:43 +02:00
Christoph Oelckers
7bea8ad6ba - fixed texture overlays for SW's sector portals. 2021-03-30 23:27:11 +02:00
Christoph Oelckers
9cccd6f89b - store plane meshes without height information. 
This avoids retriangulation when just the plane's z changes.
 2021-03-30 20:30:35 +02:00
Christoph Oelckers
6239734bdc - always create geometry for flat sprites in the collection pass. 
This still depends on Build's tsprite array which is global so its contents are too volatile for delayed geometry generation.
This needs to be refactored later but it can only be done when Polymost is gone.
 2021-03-30 19:58:42 +02:00
Christoph Oelckers
4647a0b2bc - fixed cases of small textures being used for the sky. 
Case in Point: DukeDC uses a 64x64 texture with palette remap for the sky.
 2021-03-29 23:25:43 +02:00
Christoph Oelckers
6fcb6fa1d5 - sky positioning tweaks. 
It does not use the panning info of the wall and needs a texture height relative adjustment.

Christoph Oelckers
2d0360fa55 - apply depth bias to translucent geometry. 
This is necessary to handle wall and floor sprites placed on actual walls and floors work as intended.

d9ff2fd1e2 - used display size for all texture positioning. 2021-03-28 18:22:30 +02:00
Christoph Oelckers
83760d4974 - fixed a few wall sprite rendering issues. 
* masked walls were inserted into the sprite render list, causing sorting issues and depth fighting (see Duke's cameras and the 'closed' sign in Route66/Carnival.map)
* vertical and horizontal wall sprites needed their sorting functions swapped.
* plane clipping for wall sprites used bad coordinates.

efe0d57fca - removed all the decal stubs. 
Build has wall sprite for decals so this is redundant and ultimately not usable.

f6568fee0c - rewrote SW portal setup to use static data instead of ad-hoc setup. 
This was by far the messiest game, there's two reasons for this.
First, the portal links do not need to be in an actual portal sector, so they cannot be used to detect portal sectors.
Second, the game moves portals in place, so all offsets are (0,0,0) so that not even these can be used for detection.

The only working method is the super-complicated original way to look up portals at run time, just being done at map start.
Having static portal links should reduce the render glitches quite significantly because the renderer knows now which sectors belong to a portal and can use this information to ensure proper processing.

af54cf3a3c - made SW's sector portals operational. 
Unlike the other games these are so poorly defined that the engine has to rely on the original fudging to pick the proper portal to link to. As a result they are just as limited as they always were.
In addition all the portal search code had to be reinstated.

1297e4ed02 - SW's line to sprite portals are working now. 
Also fixed a clipper issue with Blood's line to line portals.
 2021-03-24 10:33:50 +01:00
Christoph Oelckers
9903b39cf5 - make Blood's line to line portal operational. 
Note that these portals cannot be rotated, so to preserve bad setups this limitation needs to be replicated.
If we want proper line to line portals for all games they need to be made a different portal type.

46e0b16370 - fixed ordering issues in drawer 
* do not check the clipper in the collection pass to reduce number of bunches. Clipping here brings no performance gain.
* fixed the loop reset in FindClosestBunch to actually process the array's first element.
 2021-03-23 19:20:06 +01:00

Christoph Oelckers
9fe462d358 - adapted GZDoom's portal framework. 
Not tested yet and somewhat stripped down, as the portals this needs to support are a lot less complex - plus some of the issues in Doom do not apply here.

88706e8e13 - added a cache for the sector geometry. 
Now it only needs recreation if the sector changes.

93bb774573 - flat alignment. 
This still gets redone each frame for each sector and needs to be buffered

dd15fc54c1 - top texture means RENDERWALL_TOP, not that it matters much at the moment... 2021-03-19 12:02:20 +01:00
Christoph Oelckers
ff8ca99e2b - fixed y alignment of bottom textures. 
Despite other settings, they will always take the panning info from their backside.

Christoph Oelckers
f8de712b81 - fixed horizontal panning for bottom textures. 2021-03-19 11:22:24 +01:00
Christoph Oelckers
385cc8cbbd - NPOT texture alignment fixes. 
The checks in CheckTexturePosition were not correct and caused unwanted texture shifting.
Also inlined GetYPanning into DoTexture because the pow2size value is needed there and the rest is a simple one-liner to scale the panning.

2d958745b4 - fixed: Polymost must set the viewpoint if renderers are switched. 
- fixed coordinate order in renderSetViewpoint
- fixed backwall checks accidentally testing wall 0 instead of the current wall.

493294909b - fixed texture alignment 
Most cases should be correct now.
 2021-03-17 23:29:13 +01:00
Christoph Oelckers
47dce8de8c - partially fixed y-panning and removed the aspect factor. 
y-panning is still not correct for all cases but better than before. The aspect factor is not needed, it looks like an artifact of both the software renderer and Polymost.
We get the same dimensions with proper matrices by setting this to 1.
 2021-03-17 20:02:50 +01:00
Christoph Oelckers
b492cbcebb - ported my old Build-style renderer for Doom from 2008 and the wall renderer from GZDoom to work with Build data. 
It renders walls, but y-panning is still broken.
