d2ead39bcc - force framebuffers for camera textures on GL 3+ hardware. With all the postprocessing stuff added I don't think it's ok to use the screenbuffer for this anymore. 
- disable framebuffers for camera textures in legacy mode entirely. This depends on a GL_DEPTH24_STENCIL8 surface which most of these old chipsets do not support, and I really see no point to invest any work here. The worst that can happen is that oversized camera textures won't be processed, which, due to general performance issues, might even be a good thing.

8b01a88b76 - removed gl_lights_size and gl_lights_intensity. 
Both of these were inherited from ZDoomGL and in terms of light design in maps it makes absolutely no sense to have them user configurable. They should have been removed 11 years ago.

e7856ce1e3 - removed unused forceadditive parameter from gl_GetLight. 
- restricted gl_lights_additive to legacy code and removed menu entry for this.

For modern hardware this setting is completely pointless, it offers no advantage and degrades visual quality. Its only reason for existence was that drawing additive lights with textures is a lot faster, and that's all it's being used for now.

527703ae8c Fix missing flash if multisampling was on and no post processing effects active 2016-09-04 03:21:47 +02:00

217601f338 - fixed: FPortal::ClearScreen may not use the 2D drawing code anymore. 
2D calls are accumulated and then executed all at once at the end of the frame, but this one needs to be interleaved with the 3D rendering. It now uses the quad drawer to fill the portal with blackness.

aece9aaa58 - added xBRZ texture scaler after clearing the licensing conditions. A screenshot of the confirmation that this is ok has been added to the 'licenses' folder. 2016-09-03 14:01:51 +02:00

589936f570 - draw the colormap blend after postprocessing, not before it. 
- added colormap shader to postprocessing.

This replaces the in-place application of fullscreen colormaps if renderbuffers are active. This way the fully composed scene gets inverted, not each element on its own which is highly problematic for additively blended things.

4a0e082836 - fixed: The wall splitter in the translucent sorting code needs to set fracleft and fracright so that vertex generation is done correctly for the split segments. 2016-08-31 23:26:49 +02:00
Christoph Oelckers
45ff15559d - removed gl_draw_synv because with the postprocessing this is no longer useful. 2016-08-30 00:33:02 +02:00

0f0dc2c852 - implemented buffers for GL 3.x. These only get mapped during the data collection pass so the order of some things is different here. 2016-08-29 10:43:03 +02:00

c9578ae72d - create vertex buffer data for horizon portals in the constructor instead of in the draw function. 
This was the last remaining place where the vertex buffer was accessed in the render pass.

6755cb2a25 - use the quad drawer for skybox-flagged sectors. 2016-08-26 00:02:32 +02:00
Christoph Oelckers
b83c2056a8 - store the stencil caps in the reserved part of the main vertex buffer instead of constantly recreating them. 2016-08-26 00:01:51 +02:00
Christoph Oelckers
76d7b52fcd - handle the case where a wall gets drawn with an unmapped buffer and no vertex data. 
This uses the quad drawer because it can only happen with translucent walls that got split during sorting.
 2016-08-25 23:20:23 +02:00
Christoph Oelckers
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.
 2016-08-25 23:13:49 +02:00

8f331f56e2 - use MakeVertices directly in the portal code and remove all related code from RenderWall. 2016-08-25 23:02:43 +02:00

Christoph Oelckers
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.

13a2bf57e5 - 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.

071485b22e - fixed: If the resulting render style, after all adjustments, is None for the weapon sprite, do not attempt to draw it at all. 2016-07-25 11:55:47 +02:00

54a120d612 - do not process subsectors if rendering a stacked sector portal and the clipper is set to 'blocked', i.e. no visible parts are present. 
This solves the most severe occurences of sprites being drawn in front of a portal's contents. It is not a full fix, though, there's still some extreme cases where portals may glitch if some stuff gets between the camera and the actual portal area.
Normally this has to perform a full check of the subsector against the portal's camera-facing linedefs but that's too costly for those rare cases where it may be an issue.
 2016-07-23 10:23:34 +02:00
Christoph Oelckers
d405cf5b7c - fixed: Before rendering a sector stack portal the clipper needs to be completely filled, if the view point's subsector is not inside the portal. If this is not done, some setups where a recursive look into the originating area is possible may exhibit some issues. 2016-07-23 09:47:14 +02:00

It turned out that the only thing that wasn't set is the alpha function, not the blend settings themselves.

e56196eb1a Disable facing camera rotations if the actor is a flat/wall sprite. 
- It not only looks bad, it also throws off users when trying to make perfectly aligned images since the plane is distorted wildly.

cc8d84cd5d Fixed sprites defaulting to rotate around the center instead of the offsets. Seeing how it's still useful however, ROLLCENTER can still be used to center upon actors that are offsetted like monsters. 2016-07-13 09:31:22 +02:00

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.
