f3a32a7934 Might as well convert the divide to a multiply. 2013-08-20 17:04:29 -07:00

22598ceb4f Optimizations for occlusion blur (the main one being that we only need to 
sample the texture four, not sixteen, times if we turn on linear filtering
and sample between the texels).

b41fa1e03c Basic ambient occlusion effect up and running; needs tweaking and 
optimization.

3ddab484e0 Beginnings of ambient occlusion. Looks like an architectural drawing. 2013-08-15 17:52:31 -07:00

a9ccca3f72 Diffuse/add glow mode. 2013-08-14 16:13:30 -07:00

15f129f32d Added simple additive/blur-with-persist glow modes, means to cycle through 
modes.

d24e340c91 To keep the frame rate up, let's only sample eight points for the blur. 2013-08-13 14:52:35 -07:00

01cd0d2a1f Have the glow effect add half of the original texture, too, and use it on the 
follow indicator.

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).

stream.

ff0d63173c Pass the aspect ratio into the shader, since it no longer necessarily 
corresponds to the texture rectangle's aspect ratio.

c11ab45474 It seems gl_ModelViewMatrixInverse is problematic on OS X; let's try passing 
in the camera's position as transformed into model space.

1eac57dd0c #19351 - Atmosphere shaders should be handled per-pixel instead of per-vertex. 2013-05-30 15:02:11 -04:00

f0055bd419 Fixes for OS X: GLSL version must be first line in source, don't init glut 
(Qt apparently uses it?)

5138f62aef Use the "proper" alpha value (i.e., the one from the original shader). This 
makes the sky somewhat darker, but that probably just means we need more
scattering or a brighter sun.

82f16e7f34 Include the "sky from space" shaders, too, and use them when the camera is 
outside the atmosphere's outer radius.
