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.

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.

d193e199f1 - reorganized hightile offset storage. 2021-04-06 15:55:33 +02:00

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.

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.

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.

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

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

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.

dc234ea72d - implemented RR's geometry effect.
The grossest of all gross render hack that were ever done with Build...

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.

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.

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.

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.

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

6fcb6fa1d5 - sky positioning tweaks.
It does not use the panning info of the wall and needs a texture height relative adjustment.

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.

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.

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.

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.

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.

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.
