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

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

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.

c9483353ff - some more translucency checks. 2021-04-08 19:56:18 +02:00

1362a7ebc5 - added extended translucency support and did a bit of code consolidation. 2021-04-08 19:45:18 +02:00

38ecfc8fa5 - added handling for cubemapped skyboxes. 2021-04-08 12:47:31 +02:00

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.

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.

39c457bbf2 - removed a few unused CVARs carried over from GZDoom. 2021-04-04 19:35:12 +02:00

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

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.

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.

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.

e1df17964e - fixed handling of SW's shadows.
An out of range shade will only work without fog.

9cccd6f89b - store plane meshes without height information.
This avoids retriangulation when just the plane's z changes.

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.

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

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.
