Andrzej Kapolka	4f87524821	Switched back to using uniforms for light parameters, as using the fixed ... function state killed my frame rate. Also cleaned up some of the location tracking.	2014-07-22 18:03:13 -07:00
Andrzej Kapolka	be028c2b01	Fixes for local lights.	2014-07-22 14:13:51 -07:00
TonyPeng	ef4b95c6e0	Merged from master. Get rid of redundant GL fog states. Moved local light parameters to shader uniform arrays.	2014-07-09 13:27:42 -07:00
TonyPeng	56eadcb0dc	Get rid of redundant GL calls for fog. Enable and disable fog during rendering stage of voxels. Moved the local light parameters to shader uniform arrays.	2014-07-09 12:05:34 -07:00
Andrzej Kapolka	bfd00f1b15	Use local viewer model for specular.	2014-05-23 10:57:14 -07:00
Andrzej Kapolka	4f4b4c08bb	Restore specular lighting--but, per the OpenGL spec, shut off specular ... contribution if the surface isn't facing the light.	2014-05-19 12:29:49 -07:00
Kai Ludwig	51965fd283	changed ... float specular = max(0.0, dot(normalize(gl_LightSource[0].position + vec4(0.0, 0.0, 1.0, 0.0)), normalizedNormal)); to float specular = max(0.0, dot(gl_LightSource[0].position, normalizedNormal)); Calculation for specular value has to be done like in all other shaders with the unmodified unnormalized lightsource position. Otherwise the specular effect will have weird behaviour.	2014-05-16 15:44:07 +02:00
Andrzej Kapolka	d0537e7ead	Specular map support.	2014-05-06 17:32:10 -07:00
