a8e9c1832f - decided to restrict the 2.0 beta to OpenGL 4.x with GL_ARB_buffer_storage extension and removed all code for supporting older versions. 
Sadly, anything else makes no sense.
All the recently made changes live or die, depending on this extension's presence.
Without it, there are major performance issues with the buffer uploads. All of the traditional buffer upload methods are without exception horrendously slow, especially in the context of a Doom engine where frequent small updates are required.
It could be solved with a complete restructuring of the engine, of course, but that's hardly worth the effort, considering it's only for legacy hardware whose market share will inevitably shrink considerably over the next years.
And even then, under the best circumstances I'd still get the same performance as the old immediate mode renderer in GZDoom 1.x and still couldn't implement the additions I'd like to make.

So, since I need to keep GZDoom 1.x around anyway for older GL 2.x hardware, it may as well serve for 3.x hardware, too. It's certainly less work than constantly trying to find workarounds for the older hardware's limitations that cost more time than working on future-proofing the engine.

This new, trimmed down 4.x renderer runs on a core profile configuration and uses persistently mapped buffers for nearly everything that is getting transferred to the GPU. (The global uniforms are still being used as such but they'll be phased out after the first beta release.

a600a816c3 Consolidate some common code for texture mapping setup 
- R_AddLine() and R_RenderDecal() had nearly identical code for setting up
  texture mapping. These have now been spun off into methods of
  FWallCoords and FWallTmapVals.

bc450808b2 Consolidate wall texturing vars into two structs

- All texture mapping values go into FWallTMapVals.

bbc3b69a7c Remove polymost stuff 
- Maybe it will be back someday, but it's been essentially dead for nearly
  10 years, so don't hold your breath.

4cf468452c Remove slopetype from line_t. 
- Recomputing it in the only two places where it's used is trivial, so
  it's basically a waste of space to precompute it.

1ec58011d2 - start of light buffer implementation so that we don't have to use uniform arrays which appear to be broken on AMD. 2014-07-31 00:44:22 +02:00

ef8f66c9a1 - removed the code for hardware alpha testing again because it didn't work anymore with how things are set up now. 
- we need to check all GL versions when trying to get a context because some drivers only give us the version we request, leaving out newer features that are not exposed via extension.
- added some status info about uniform blocks.

a922ae04cc Use Blood player starts 
- Blood's maps use thing types, much like Doom's, so getting its player
  starts is easy. There's no need to synthesize a start from the editor
  position like with other Build maps.

6af441c4d7 Dup frames shouldn't adapt. 
Adapting during a dup frame caused jittery network performance
(especially when using high dup values).
The demoplayback check also didn't need to be there anyway.

355dd1c2f5 - fixed some issues with setting the vertex dirty state. It was also called from several sector init functions and copy code for Boom deep water. The only case where SetPlaneTexZ should call it is from the interpolation code so this is a special case now. 2014-07-28 18:01:01 +02:00
