- changed the license of the OpenGL renderer to LGPL v3.
...
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

- removed most of the specific options for legacy hardware and consolidated them in one variable (does not work yet.)

- fixed: The model matrix must be disabled right after rendering the sky dome, so that it won't get used for the skyfog layer.

- fixed vertex coordinate ordering for the sky cubemap.
...
This was done differently for FFlatVertex and FSkyVertex which caused a switch of the y and z coordinates for the skybox image.

- 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.

- fixed: The sky renderer must not only alter the light mode but also reset the software light level to a 'disabled' value.

- fixed: For cubemapped skies with one texture for all 4 sides the texture was never set before rendering.

- fixed: The depth clamp setting needs to be tracked per portal so that it can be properly restored afterward.
...
Regular skies need it off but SkyViewpoints need it on - and all others need to use the parent's setting.
So without engine side tracking we can end up rendering the sky with this setting off, resulting in omission of the fog layer.

- route texture binding through the renderstate class for better control. Currently it's just a direct passthrough but this will change.

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.

2014-07-17 10:04:20 +02:00

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

removed all GL 2.x code.
...
After thinking about it for a day or so I believe it's the best option to remove all compatibility code because it's a major obstacle for a transition to a core profile.
2014-06-21 15:50:32 +02:00

- fixed compile error in gl_skydome.cpp
...
- disable GL_ARB_buffer_storage when a -glversion parameter less than 4.0 is given. According to the spec this extension requires 4.0 so if emulating something lower it should not be used.
2014-06-14 14:58:17 +02:00
Christoph Oelckers
5e22c82e79
- use buffer for rendering the sky on all GL versions since the differences for making GL2.0 work are rather small.

Christoph Oelckers

- rewrote sky dome rendering to use a static vertex buffer if not on OpenGL 2.x.

Christoph Oelckers
887d35d559
- remove colormap from texture generation parameters. The one remaining special case, alpha texture on old hardware is now handled by the currently set texture mode at the time of use.
...
- use the cleaned up decal lighting code from the first GLEW branch.
2014-05-11 19:44:19 +02:00
Christoph Oelckers
