- GZDoom now runs on an OpenGL core profile. :)
...
It's probably still necessary to replace GLEW with another loader library. GLEW is pretty much broken on core OpenGL without some hacky workarounds...

- added some checks to the wall rendering code that will allow to disable the clip planes in many cases, even when a plane mirror portal is active. This also solves the precision issue with using world coordinates for clip checks.
2014-07-13 17:15:17 +02:00

- for some reason using world coordinates for clipping in the shader is somewhat imprecise so the clip plane heights have to be adjusted a bit for it.

- since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware.

- use a uniform array to store vertex data to render dynamic stuff on GL 3.x hardware without the ARB_buffer_storage extension.
...
Due to the way the engine works it needs to render a lot of small primitives with frequent state changes.
But due to the performance of buffer uploads it is impossible to upload each primitive's vertices to a buffer separately because buffer uploads nearly always stall the GPU.
On the other hand, in order to reduce the amount of buffer uploads all the necessary state changes would have to be saved in an array until they can finally be used. This method also imposed an unacceptable overhead.
Fortunately, uploading uniform arrays is very fast and doesn't cause GPU stalls, so now the engine puts the vertex data per primitive into a uniform array and uses a static vertex buffer to index the array in the vertex shader.
This method offers the same performance as immediate mode but only uses core profile features.

- removed obsolete gl_lightbuffer code.

Christoph Oelckers

- fixed: FBufferedUniform1f didn'T work because it used an int as its buffered value.

removed error suppression code from shader compilation.

With GL 2.x support the engine still had something to fall back on, with that removed it needs to abort.

Christoph Oelckers
2925c96b59
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
Christoph Oelckers

- changed alpha texture handling to avoid using the deprecated GL_ALPHA8 texture format unless we have a compatibility context of an older GL version.

- 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.
