8f45664089 - fixed: Fog boundaries were not drawn on line portals.
There's two restrictions, though:

* on one-sided-line portals fog boundaries will not be drawn.
* the filler sector behind the portal may not have a sky ceiling texture. This is because the drawing code contains several sky checks which get in the way here.

4eb5f10b02 - use normals to have proper light attenuation. So far only implemented for walls and flats. Models are planned but need some thinking about how to efficiently collect all required lights for an object. 2016-10-03 16:09:32 +02:00

8b6e09ca09 - 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.

3389a5a74e - removed most of the specific options for legacy hardware and consolidated them in one variable (does not work yet.) 2016-09-01 11:52:52 +02:00

45ff15559d - removed gl_draw_synv because with the postprocessing this is no longer useful. 2016-08-30 00:33:02 +02:00

4598c4138c - added vertex initialization for walls in the processing pass for core profile without persistent buffers.
This is slower than doing it in the render pass so it's only active when actually needed - it's also slower than using a client array so this code only gets used when there is no choice but to work with a 3.x core profile context.

9c9edbffdb - on older ATI drivers where the clip planes are broken, only disable the clip planes themselves, but not OpenGL 3.x so that dynamic lights still work as intended.
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.

2b92048a5b - renamed the texture coord variables in GLWall.
It makes no sense having them organized differently in this struct than what the rendering code needs. This saves one redundant copy operation and a function-local static variable.

0a94371974 - reinstated old code for rendering fog boundaries and mirrot surfaces without shaders.
- added code for filling the render list for textured dynamic lights. This is not yet active because no code is present to handle this data.

a0a530945d - added new sector type 90 which designates a sector that is being used as a cubemapped skybox, in case someone wants to make one of those without using an actual sky for this. 2016-04-14 13:22:15 +02:00

8a20f901a3 - removed the non.slope special handling in the wall processing code.
This may have made some sense when I added this 11 years ago but on a current computer it actually hurts performance a bit due to the branching that is involved - the code runs a bit faster with those special cases removed.
