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.

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.)

00d59459a1 - fixed creation of true color textures and disabled fog in palette mode.
The fog should go away entirely but in palette mode it made everything too dark.

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

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.

623511021f - cleaned up the fragment shader and gave it some workable structure.
Important note here: branches are not the root of all evil - but mangled unreadable code actually is!

7185bbad81 - fraqment shader cleanup part one. 2019-10-06 21:23:51 +02:00

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.

3d538b4c8f - use explicit vertex attributes for everything.
No more glVertex, glTexCoord or glColor calls anywhere.

0720ad5fd5 - make all varyings in the polymost shader explicit and declare the surface shader as v3.30 as it already used modern syntax. 2019-10-06 10:29:17 +02:00

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.

8fd8d0858c - started modernizing the shader.
This is one unbelievable piece of weird coding based on the 15 year old concept to avoid conditionals at all costs.
As a result the code is totally unreadable and no longer really portable to modern OpenGL.
This has to be done in small pieces.

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.

d058084c10 - added an engine resource file.
Currently this only contains the main Polymost shaders and the resources from nblood.pk3.
The latter cannot be used yet because the Build resource management system is too stubborn to add the newly added file without some changes.
It's better to refactor the entire system instead.
