I’m curious as to how litle information can be used to display font textures in my GUI.
Currently I use GL_LUMINANCE_ALPHA with identical data in my greyscale and alpha channels. I must admin I use someone else’s font file format so I have no idea s to why it’s done this way.
Can I draw text with a GL_LUMINANCE only texture? If so do I need to do anything different?
Many thanks,
Chris
