Andrzej Kapolka	15f129f32d	Added simple additive/blur-with-persist glow modes, means to cycle through ... modes.	2013-08-14 14:14:47 -07:00
Andrzej Kapolka	d24e340c91	To keep the frame rate up, let's only sample eight points for the blur.	2013-08-13 14:52:35 -07:00
Andrzej Kapolka	01cd0d2a1f	Have the glow effect add half of the original texture, too, and use it on the ... follow indicator.	2013-08-13 14:22:29 -07:00
Andrzej Kapolka	b05b43f027	Render to texture first, rather than copying from the frame buffer. Copying ... from the frame buffer requires it to have an alpha channel, which actually does something on OS X (meaning we have to set it to 1.0). We're going to want to render to texture anyway for SSAO (or other effects).	2013-08-13 12:27:52 -07:00
