756ed1c14b - removed the workaround to make Lunatic Fringe not glitch. 2021-12-30 09:56:52 +01:00
Christoph Oelckers
c141c89cfd - fixed the clipper. 
* must do proper checks for merged ranges when inserting new ones. The checking code assumes that closed ranges are contiguous.
* when discarding parts of overlapping ranges this may not use merged clip values for its checks.
* ranges that have their clip values altered must be released and reinserted to ensure everything is correct.

f152a4d9b5 - clipper clean up. 
The horizontal part of the logic should work now.

dddf48fd3e - cleaned up and renamed buildtypes.h. 
Content was reordered so that the file can contain the inlines belonging to the map data types that previously had to be stored elsewhere.
Also moved out of the Build folder because virtually everything in here can be traced to content available in Duke Nukem 3D's and Shadow Warrior's source releases.

4a5de6f56e - make sure that all changes of wall coordinates invalidate associated data. 
walltype::move should be the preferred function to be used for this, otherwise walltype::moved needs to be called.

0e6242626c - removed the viewpoint from the clipper as we don't need this. 
ClipWindow will go elsewhere, it has no place here.

4700299fc6 - fixed bad assert. 
This can indeed be called with both angles being identical and should accept this case.

7c5080f654 - reimplemented sector splitting. 
With the new setup this is a lot easier than with the old one.
 2021-12-30 09:53:10 +01:00

fc41a2bd85 - renamed sections2 and sections2PerSector. 
No more need for a '2'.

Christoph Oelckers
37e49ed775 After this any old mesh has become invalid and needs to be rebuilt.

e79cd8d87f - don't store sprite indices in walltype::portalnum 2021-12-26 23:09:54 +01:00
Christoph Oelckers
eaff9e359f - refactored the owner index in tspritetype. 
This is now a separate type from spritetype which contains an actor pointer instead so that sprite display can be handled without requiring a static sprite array.

7546cf3a4b - replaced vec3f_t with FVector3. 2021-12-14 09:58:01 +01:00
Christoph Oelckers
a899055f50 - fixed: in palette emulation mode, assume all textures to be non-translucent. 
These need to force an alpha test, which is disabled for textures with translucent texels.

2253a418c7 - Tidy up some of the indentations that were badly resolved in the previous commits merge conflict. 2021-12-13 07:39:01 +11:00
Christoph Oelckers
054d81fc8e - fixed logic for discarding walls in new renderer. 
The case being checked here may decide not to add the wall to the clipper but it must still be rendered.
Information for determining visibility is not sufficient in case of sector overlaps which can happen with rotating doors or poorly set up sector objects.

6cec61683d - fixed incorrectly placed tileUpdatePicnum call in new renderer for sprites. 
This was only in the regular sprite call and did not affect models or voxels.

62d0d3712e - use a sprite flag to mark mapped sprites. 
This avoids another global array which needs to be addressed by sprite index.

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.

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.

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

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.

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.

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.

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.

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.

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.

cdf89b9175 - portal rendering fix when viewing through two-sided walls outside the actual portal area.

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

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.

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.

caa8efd3d5 - fixed renderer to avoid bunches of walls that wrap around behind the camera's back. 2021-04-07 16:09:25 +02:00

4bd44f9d62 - flat sprites use different visibility rules. 
Hooray, Build engine, yet another totally nonsensical magic factor with absolutely no reason why...

6ad0089524 - fixed flat sprites using the sector bit names for checking for being flipped. 
Thank you, autocompletion... :(

59f18f5fa7 - ensure that all HWSprites are oriented with z1 > z2. 
This is required by the sorting code to work as intended.

f9f1d591b3 - must set up fog before textures. 
Otherwise the PickTexture callback won't get all needed info.

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°.

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.

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.

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.

172e3996bb - HWSprite::Process(): Added x-off-by-one-fix for sprites similar to yspans from b7bad558da. 2021-04-05 19:37:00 +10:00

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.

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.

1201cc71ef - fixed voxel rendering. 
No, that 'while' was even pointless in Polymost, much more here where it runs within another loop.

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.

d7a13fc9f2 - same for the new renderer. 2021-04-03 21:40:32 +02:00

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.

54eee347a6 - do y-flipping of wall textures correctly. 
1.f - h is not correct for NPOT texures due to hpw they tile.

638f19172a - voxel rendering. 
The stock voxels of Blood and SW seem to work so far, but not all edge cases have been tested.

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.

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.
