- the harmless changes of the failed refactoring of the shader.

- 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.

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

- 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.

- 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.

- 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.

- make it work again.

- 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.

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

bd4e4834e3
- moved the main shader and its entire uniform maintenance into the backend.

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.

- all non-shader related GL calls are gone from the main code base.

glColor calls refactored.

- abstracted away more OpenGL calls, in particular all matrix access.
2019-10-04 18:12:03 +02:00

- 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

- refactored texture setup to use an intermediate layer.
2019-09-18 22:16:15 +02:00
Christoph Oelckers
d63cf04e06
- removed the compressed texture cache.
...
This is a pointless relic from the past and makes zero sense with modern graphics hardware.
2019-09-17 20:18:18 +02:00
Christoph Oelckers

- hooked up the texture management.
...
Not in active use yet!

- texture sampler class added, not used yet.
2019-09-16 22:56:48 +02:00
Christoph Oelckers
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.
2019-09-16 21:08:42 +02:00
Christoph Oelckers
318009fd69
- added a centralized drawer and converted the main geometry drawer to use it.
