Christoph Oelckers	c5b3b9e107	- moved the viewpoint buffer to hwrenderer.	2018-10-28 13:26:47 +01:00
Christoph Oelckers	b51cc8b115	- base the viewpoint buffer on IDataBuffer.	2018-10-28 13:18:13 +01:00
Christoph Oelckers	5f838d52b9	- some cleanup on the OpenGL interface and its flags. ... Most importantly, the separate command line options for switching on the legacy buffer handling have been removed. There's really no need for them anymore, because unlike in earlier versions many of the implementation differences no longer exist - with the exception of where the light and vertex buffer contents are generated. For testing this, -glversion 3 is sufficient.	2018-10-20 12:55:25 +02:00
Christoph Oelckers	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.	2018-09-16 22:38:20 +02:00
Christoph Oelckers	3dcaa509ef	Merge branch 'master' of https://github.com/coelckers/gzdoom	2018-09-08 12:10:34 +02:00
Christoph Oelckers	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.	2018-09-08 10:16:31 +02:00
Christoph Oelckers	8b26b6dd1e	- reworked fog uniforms to move the global fog mode setting to the viewpoint buffer.	2018-09-06 19:14:30 +02:00
Christoph Oelckers	5e39890118	- use a uniform buffer for per-scene data like rotation matrices.	2018-09-02 18:40:36 +02:00
