98c919fbe4 - g_visibility stuff 2022-01-11 00:12:32 +01:00

e2e3b4482d - do some better sorting of slope sprites. 
Splitting by translucent floor plane is essential, splitting by wall not that much - sorting by center point should be sufficient here.

eb00fe52db - more spritetype references eliminated. 2021-12-30 16:11:14 +01:00

9bbb54fe2e - Replace every line that just contains spaces or tabs with an empty line feed in all files except 3rd party libraries. 2021-12-30 20:30:21 +11:00

d46a7abb0e - better wall sprite handling. 
When they are directly on a wall, project their coordinates onto the wall to eliminate the imprecisions from Build's ad-hoc setup.

b1d8f92ded - added wall edge splitting for gl_seamless. 2021-12-30 09:58:44 +01:00

059412b75e - first batch of routing all write access to sectortype::ceilingz and floorz through a function interface. 
We need this for implementing "precise" rendering to flag vertices as dirty.

d0143db8fe - got rid of sx() and sm() inlines. 2021-12-30 09:57:13 +01:00
Christoph Oelckers
beddf1e1ca - add slope sprite support to the new renderer. 
Some fudging was needed to avoid positioning problems as the renderer is more sensitive to this than Polymost.

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.

7a9596ae81 - use SectionGeometry for 3D rendering. 2021-12-30 09:53:09 +01:00
Christoph Oelckers
37e49ed775 After this any old mesh has become invalid and needs to be rebuilt. 
- use only one Section type.

ca19c265f8 - interface from Section2 to the flat processing. 2021-12-30 09:53:07 +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.

29769dd673 - fixed engine code warnings pointed out by XCode 13. 2021-10-08 19:06:41 +02:00

d4eb54d686 - render free standing wall sprites without depth bias. 
Otherwise they can end up badly ordered with walls.

5e94eaff8e - new renderer: handle light level underflows. 2021-05-16 18:50:54 +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

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
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.

389340f97c - use sections for rendering. 2021-05-03 00:15:09 +02:00
Christoph Oelckers
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.

2b1072eb91 - fixed bad sector addressing in flat sprites drawer. 2021-04-14 19:17:40 +02:00

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

2e191f2742 - consolidated the SetLightAndFog code fragments. 2021-04-10 10:34:20 +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

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.

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.

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

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

85020b374a - use texture clamping on non-tiled walls. 2021-04-01 19:21:24 +02:00
Christoph Oelckers
7bea8ad6ba - fixed texture overlays for SW's sector portals. 2021-03-30 23:27:11 +02:00

fa44d75e98 - draw regular sprites. 
Mostly functional, but the projected size is off.
 2021-03-27 23:12:41 +01:00

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

7dd5b508c8 - flat rendering WIP. 
Still buggy triangulation and no texture alignment, but it renders something.

547ed4e415 - route everything through the full backend, now completely bypassing the intermediate GLInstance layer. 2021-03-18 17:18:03 +01:00
Christoph Oelckers
6068427270 - port the bunch drawer to the backend's core. 2021-03-18 12:32:31 +01:00

af6c6c8ef0 - added the DrawInfo class. 2021-03-18 10:23:53 +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.
