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
