View Full Version : Iluminance and Intensity

What is the diference between GL_ILUMINANCE and GL_INTENSITY in glTexImage* function?
one difference is with modulating
GL_LUMINANCE C=CfLt A=Af
GL_INTENSITY C=CfIt A=AfAt
thus the alpha calculations are different (colour is the same though)

OK, I undestand that, but what is Lt and It in that equation.
What is LUMINANCE and what is INTENSITY?
