36f87b7135 - removed gl_light_ambient. 
This really serves no use anymore and is mostly a remnant of old times with dark CRT monitors. The default ambient level was set at 20, meaning a sector light level of 40. This is a value actual levels rarely get to, except when using some lighting effects - but it's for those that the ambient clamping did the most damage.

1e950d75bd - made dynamic light attenuation completely opt-in. This can be done either by setting a MAPINFO option for lights that do not automatically specify it and with a light property. The light property will always take precedence, if set. 2016-12-07 23:17:18 +01:00

cfa6b817b5 - made bloom and tonemap settings game specific and save all related CVARs. 
As was pointed out: "That said, there is one minor problem - different game artstyles can constitute whether Bloom is turned on, which tonemap is used, etc. For example, when playing Doom, I like having my bloom on, but if I am going to start playing the Adventures of Square, the art style and bloom don't mix, in my opinion. For this, I have to remember to switch my bloom settings every time I switch IWad"

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.

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.

9555617816 - fixed: The default for position.w is 1, so gl_quaddrawer.cpp needs to set this, too, for the uniform vertex positions. 2016-08-22 22:02:02 +02:00

250be72939 - added handling for drawing with uniform vertices. It draws something but in the wrong place. Right now I have no idea what's happening... 2016-08-22 15:31:23 +02:00

7ba5acfb35 - added quad drawer interface so that this part can be done without altering a vertex buffer. 
So far it's only the framework, the new code is not active yet.

353a464f5b - fixed: The 2D texture drawer did not reset the render state's color so any previously set desaturation would persist. 2016-08-13 22:15:00 +02:00

e5f88a9883 - fixed: The textured automap was not using correct light levels. 
In order for the externally passed vertex attribute to work the buffer's color attrib array needs to be disabled for these.

675822004d - use static buffer data and a uniform to handle the texture positioning of the present shader. 
That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle.

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.
