Colored textured font

Recommended Posts

Hi I''m using textured font to draw text over my background scene. I use a black and white texture with anti-aliased characters and an alpha channel to make the black part transparent. It works fine but i''d like to be able to change the text color without having to load anything else (ie replace the white of the character by another color). Of course the text should still be blended correctly with the background. Is there a simple way to do this? thanks zedd

One of the common methods (and the way I do it) is to use vertex lighting. If you have a solid white texture and specify red light on it, it will turn it red (of course).

provided u have the alpha channel of the etxture setup well
use
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
glDisable( GL_LIGHTING )
glColor4f(1,0,0, 1) // for red
glEnable( GL_BLEND );
glBlendFunc( GL_SRC_ALPHA. GL_ONE_MINUS_SRC_ALPHA )
