Christoph Oelckers 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.

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

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.

Christoph Oelckers 3fb5154dc9 - make it work again. 2019-10-05 14:17:59 +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.

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
Christoph Oelckers 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.

Christoph Oelckers ae1e090716 - all non-shader related GL calls are gone from the main code base. 2019-10-04 21:13:04 +02:00

Christoph Oelckers cb80e877ff - refactored fog and depth func setting into GLInterface. 2019-10-04 18:44:16 +02:00
Christoph Oelckers 204abab724 glColor calls refactored. 2019-10-04 18:25:18 +02:00
Christoph Oelckers 96c0c3197c - abstracted away more OpenGL calls, in particular all matrix access. 2019-10-04 18:12:03 +02:00
Christoph Oelckers ad4527c8be - initialize the GL backend in the proper place.
As long as there are still video mode switches this needs to be in the video mode switching function.

Christoph Oelckers e0f823a492 - refactored texture setup to use an intermediate layer. 2019-09-18 22:16:15 +02:00
Christoph Oelckers b1763a8f4a - hooked up the texture management.
Not in active use yet!

Christoph Oelckers 2b439ae181 - work on backend 2019-09-16 23:28:26 +02:00
Christoph Oelckers 9edf6be10d - texture sampler class added, not used yet. 2019-09-16 22:56:48 +02:00
Christoph Oelckers 318009fd69 - added a centralized drawer and converted the main geometry drawer to use it. 2019-09-16 19:35:04 +02:00
