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	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
