3b1500438d - got rid of VAO's. they have no impact on performance and are a general nuisance if some render paths cannot use them.
- cleaned up gl_interface and removed gl.compatibility.

45cf65afbd - moved the aspect ratio correction factor from the projection to the view matrix where it should have been from the start.
- removed the mCameraPos variable in FGLRenderer because it was only used in one place where it is just as easy to use the global viewx/y/z variables directly.

e5cd90f323 - use separate vertex buffers per model to avoid large memory usage peaks. Also delete the geometry data for the models once it has been copied into the vertex buffer. 2014-10-24 11:43:25 +02:00

1050013017 major cleanup of the texture manager:
- use sampler objects to avoid creating up to 4 different system textures for one game texture just because of different clamping settings.
- avoids flushing all textures for change of texture filter mode.
- separate sprite and regular dimensions on the material level to have better control over which one gets used. It's now an explicit parameter of ValidateTexture. The main reason for this change is better handling of wall sprites which may not be subjected to such handling.
- create mipmaps based on use case, not texture type.
- allows removal of FCloneTexture hack for proper sharing of the same sprite for decals and other purposes.
- better precaching of skyboxes.

7967082e60 - use the light buffer to handle dynamic lighting. 2014-08-01 20:59:39 +02:00

b8bcbe819b - removed texture based dynamic lighting. For GL 3.x the shader approach is always better.
- fixed: sky fog was not unset.

1efc2938b7 - implement model vertex buffer and draw MD2 models using it instead of using the GLCommands from the model. 2014-06-29 23:24:16 +02:00

8d9a90cd22 - rewrote sky dome rendering to use a static vertex buffer if not on OpenGL 2.x. 2014-06-14 01:24:28 +02:00

b9a6fe80a4 Do not use the shader to handle STYLEF_RedIsAlpha.
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...

This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

978ace241c - removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state.
- removed cm parameter from many functions.

b61ef3a107 - bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2.
- removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore.
- disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.
