3d47652d08 - had a look at Exhumed's shade tables and implemented the necessary adjustments for the 3 with abnormal gradients. 2019-12-31 22:53:03 +01:00

5830e72ab0 - fixed some rotatesprite issues:
* scissor was not applied
* texture coordinates were fetched from the wrong texture, courtesy of using global variables.

6459f4e532 - refactored rotatesprite to really use the 2D drawer.
Mostly working, except clipping and weapon sprites.

737bf15ad8 - added GZDoom's postprocessing/presentation code.
Compiles but only draws a black screen. Something must be missing but no idea yet what that might be.

68a3a60d0b - Exhumed menu tweaks - draw a background and caption for the option menus the game originally did not have.
- fixed a crash in the 2D drawer when two consecutively allocated vertex buffers had the same address. Strangely this only occured with Exhumed but not the other games
- fixed Exhumed crashing with sound disabled.

120a985b98 - disable palette transparency for color 255 when running an animation.
There's several intro cutscenes using the full palette and for these the color must not be nulled as it should for in-game textures.

62ecedf1f8 - got it to the point where it can render to the GL surface from the native backend. 2019-12-23 19:37:40 +01:00

dc60c7f72e - fixed use of brightmaps.
Due to the blending they are essentially inactive on translucent content and Duke Nukem heavily abuses this.

3be9deb070 - removed the different shadeDiv for Ion Fury.
This isn't necessary and was apparently caused by a bug that got fixed in the mean time.

79561ace09 - use the precalculated or script-specified fade colors, if present. 2019-11-10 21:11:17 +01:00

cae710bd59 - fixed alpha threshold.
Not only is this a deprecated feature - it also does not work right when complex lighting is at play, it must be done in the shader to get proper results.

85d377647a - tweaked the fade ramp a bit.
For Duke Nukem and its direct offspring (Nam, WW2GI and Redneck Rampage) the ramp is not a linear fade from 0 to 1, it needs to be a little darker than that.
Unfortunately the proper factor needed here must be set manually, this cannot really be calculated from the lookup tables.

9437387b4a - fixed handling of FogDisabled flag 2019-10-20 00:45:47 +02:00

bb4a19cf3a - added a few more texture formats to FHardwareTexture.
For brightmaps we do not need full RGBA8 data with mipmaps - RGBA2 without mipmaps is fully sufficient here and will save a lot of video memory.

7d2f61db2e - converted all boolean parameters of the shader into a single flag word.
- discarded the idea of transient palettes because the maintenance here stood in no relation to the savingd.

2152780806 - added some hackery to render voxels properly again.
Something about their data preparation is not right, their depth looks totally off and causes fog to become to dense.
One more reason to reconstruct the renderer in a sane fashion.

cd7bbe35a8 - removed all legacy fog code. 2019-10-19 15:52:46 +02:00

bc986b8054 - make the engine consistently use BGRA data - the internal palettes were still RGBA, which caused problems down the line.
- increased cache size to 200 MB (Note: The cache really needs to be replaced with something better that can adapt better to a system's RAM size.)

dab7c43f7c - fixed all compiler errors.
It mostly works again, but still has a few glitches.

23265ad213 - rework of texture management for models
Voxels yet to do.
This also removes the redundant texture matrix for the glow texture.

530a9944f7 - texture loader redone but not tested yet
Models are currently non-functional and need to reroute their texture handling to the global texture manager instead of handling everything themselves.

Voxels also need a bit of work to make their texture management more automated.

bef8c9ae76 - hictinting cleanup.
This needs to be moved into the backend, and partially into the shader. So far this only removes the code from the main rendering logic, the final implementation is not done yet.
It had to go because it required the main rendering code to look deep into the texture data which would be a major blocker for refactoring.

c588cd499a - let GLInstance::Draw set the palette indexing mode.
This can be trivially decided based on the texture type, so there's really no need to let the higher level code deal with this.

fbc7e626e9 - removed the fullbright render pass, because this is better set up as a shader option.
- also removed the legacy fog modes because their implementation did not mix well with the texture system - they are also not really useful to begin with.

The last fog mode will most likely also be removed once true color shading is working but that one is less of an issue.

1407c18f8b - cleaned out some remains of the non-indexed render path.
All of this will be redone in the backend.

1fee7a5f01 - cleanup of texture creation code.
There were several mostly pointless options complicating all of this.

7131fe6c6e - use separate textures for the palswap shade tables.
This creates a lot less mess than one big texture and also allows easier use of texelFetch in the server which is preferable for data textures.

ef2de97077 - the harmless changes of the failed refactoring of the shader. 2019-10-06 19:32:35 +02:00
Christoph Oelckers
cf30f5560b - upgraded the polymost fragment shader to GLSL 3.3 as well, removing all legacy features from it.
The only compatibility mode feature left is the main drawer function using glBegin/glEnd but changing that is not as urgent as the rest.
This also cleans up the fog application and adds the exponential fog mode again that somehow got lost over time.

71d132b470 - use explicitly declared matrix uniforms.
The builtin matrices are no longer available in modern GLSL, preventing an upgrade of the shader.
Also perform better reporting of shader compilation errors.

126f670239 - draft class for in-game textures.
These will abstract away all the gory details so that the using code only sees a single entity to use.

93ad83b380 - use GZDoom's texture backend to read hightile textures. (Hightile tinting code moved to the shader but isn't active yet.
- remove all code for faking gamma correction through palette manipulated images.

3c193bb243 - moved the animvpx shader to the backend code.
This removes the final access to OpenGL from the rest of the source, with the exception of the glFinish call in the swap code.

b83349fe6b - moved the surface shader to the backend and the shader source to the resource file. 2019-10-05 13:09:15 +02:00

6536d910b3 - all drawing is being routed through the interface layer, all vertex buffers are gone.
No big loss here, none of them made much sense performance wise.
