c8852b8fea - enabled the linear shadowmap filter. 
Although this doesn't look as good as the PCF version it is a lot less calculation intensive and therefore more suitable for weaker hardware.
It also tends to bleed through walls a lot less.

bc1e659c7b Revert "- reworked fog uniforms to move the global fog mode setting to the viewpoint buffer." 
This reverts commit 8b26b6dd1e.

This was causing problems with light mode 2 because some edge cases were no longer handled properly.

1eb1d8d280 - fixed math imprecisions in horizon vertex generation. 
Floats are not precise enough to be used as a loop counter.

1c3d4b46c6 - fixed the use of Doom-Legacy-style 3D floor lighting in light mode 8. 
Legacy used some strange blending formula to calculate its colormaps for colored 3D floor lighting, this is not available in the software lighting mode, so for these the engine has to temporarily revert to light mode 2 to render them correctly.

dd971805af - fixed: The viewpoint buffer was mapped write only but read from. On old hardware it wasn't even mapped. 
Changed to cache the needed value in a CPU-side array so that the buffer access is not needed.

22e8c57a59 - reset the viewpoint buffer only once per scene, not per viewpoint. 
This doesn't work for camera textures because they are a separate viewpoint.

bec588eaf4 - moved the two remaining functions from gl_wipe.cpp to gl_framebuffer.cpp and deleted the file. 
The single most hideous thing in the GL renderer is finally gone. :)

ecf6e3f620 Sanitized the Being/End2D interface so that it can be used to keep the attribute buffer mapped while processing 2D commands. 
For this to work the 2D mode has to be properly set and unset at the right places so that no double mapping occurs and no render operation can happen while in 2D mode.

b6ff468aaf - creation of dither texture no longer affects active unit 
Red checkerboard was rendered upon startup instead of
* the first saved game's thumbnail
* the first game frame

ecdc485e05 - Allow specifying monitor bits-per-channel for dithering output. Not all displays are created equal, so this option is actually important for specifying the exact amount for your display. 2018-08-09 15:13:26 -04:00

7e69cd862e - restore the viewport after the SSAO pass. 
This runs through the generic postprocessing code which restores the screen's viewport but since this is run in the middle of the scene it needs to restore the scene's viewport (i.e. the window controlled by screenblocks.)

9768698eda - do not use SSBOs for dynamic lights on Intel graphics hardware for performance reasons. 
This was already disabled for GL 4.4 and lower but also needs to be done for Intel's GL 4.5 drivers.
Unlike before this is now exclusive to the light buffer, the shadowmap feature is not affected anymore, although that should be impossible to use anyway on all affected hardware due to lack of computing power.

6076f0a69d - disable any texture clamping for textures with a user shader. 
This cannot be reliably determined so the least restrictive setting must be used.

d84497c85a - don't let the video scale let the screen end up with a client size less than 320x200, which may cause undefined behavior and trigger asserts in debug builds. 2018-07-22 11:40:12 +02:00

When refactoring the screen scaling one line too many was altered by accident.

a841602d70 - change the software renderer to render to a DSimpleCanvas like the old D3D9 target did. Then use the drawer threads to memcpy the result to the PBO 2018-07-20 05:48:15 +02:00

f62e2f9ba3 - fixed: The stencil cap may never write to the depth buffer. 
Due to the way nested portals work this will block rendering of the nested cap entriely and cause some visual glitches when looking straight up or down in such a sector.

2c86c4e942 - fixed: When deleting a camera texture's depth buffer, the corresponding variable must also be cleared. 
Thanks to OpenGL's messed up state system this didn't cause some clear failure but just reused the last bound buffer instead which may not have had a matching size.

d58d1e21d0 - removed the texture invalidation check from FHardwareTexture. 
This is not needed anymore because only warp and camera textures still implement CheckModified and both are excluded here.

7817e6a7b2 - moved the texture binding code back to the OpenGL specific parts. 
turns out that this cannot be consolidated with Vulkan because the semantics are far too different here.
