Christoph Oelckers	3c16a23865	- when rendering mirrors, discard subsectors lying behind them.	2016-01-27 12:02:43 +01:00
Christoph Oelckers	ef7bcb3a66	- implement Eternity-Style flat and horizon portals. Not tested yet due to lack of material to work with.	2016-01-11 15:07:58 +01:00
Christoph Oelckers	d868f60f6c	- since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware.	2014-07-13 12:14:12 +02:00
Christoph Oelckers	c39318f406	- use vertex buffer and reuse of data for stencil drawing. A stencil needs to be drawn multiple times with the same polygons so this is a good place to optimize.	2014-05-31 09:32:17 +02:00
Christoph Oelckers	399d0974ab	- added GL render as of SVN revision 1600.	2013-06-23 09:49:34 +02:00
