Christoph Oelckers	bd0c8acd46	- replaced detail matrix with a two element scale vector because that is all that is needed.	2020-05-31 12:23:35 +02:00
Christoph Oelckers	d752e33909	- removed the unused SurfaceShader class.	2020-05-31 11:47:19 +02:00
Christoph Oelckers	286d53d3bf	- added the missing handling for the basepal tinting.	2020-02-11 20:55:47 +01:00
Christoph Oelckers	55dab6d3d3	- hooked up the high color texture colorization code. ... Not tested and probably still not working correctly, the entire feature was a nearly impenetrable mess of convoluted code. This definitely needs verification with multiple mods using it.	2020-01-11 22:18:06 +01:00
Christoph Oelckers	fb985d2503	- more macOS compilation fixes ... Still not complete…	2020-01-07 01:11:19 +01:00
Christoph Oelckers	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.	2019-11-10 10:01:31 +01:00
Christoph Oelckers	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.	2019-10-20 01:14:48 +02:00
Christoph Oelckers	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.	2019-10-19 22:46:37 +02:00
Christoph Oelckers	cd7bbe35a8	- removed all legacy fog code.	2019-10-19 15:52:46 +02:00
Christoph Oelckers	23265ad213	- rework of texture management for models ... Voxels yet to do. This also removes the redundant texture matrix for the glow texture.	2019-10-18 14:04:32 +02:00
Christoph Oelckers	1407c18f8b	- cleaned out some remains of the non-indexed render path. ... All of this will be redone in the backend.	2019-10-10 19:40:33 +02:00
Christoph Oelckers	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.	2019-10-08 01:08:08 +02:00
Christoph Oelckers	7713860b63	wip.	2019-10-07 00:14:16 +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.	2019-10-06 12:42:35 +02:00
Christoph Oelckers	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.	2019-10-06 10:19:51 +02:00
Christoph Oelckers	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.	2019-10-05 13:38:02 +02:00
Christoph Oelckers	b83349fe6b	- moved the surface shader to the backend and the shader source to the resource file.	2019-10-05 13:09:15 +02:00
Christoph Oelckers	bd4e4834e3	- moved the main shader and its entire uniform maintenance into the backend.	2019-10-05 12:28:08 +02:00
