I want to display a logo on my OpenGL program. My logo is a black BMP with the logo in white. You know what I mean I hope.
Example : a cross-hair in on a black BMP.
My question is :
How can I do to put the alpha value for black at 1.0 for only displaying my logo in white ?
Maybe I’m wrong but if the texture is black with a white logo and you just want the logo to see trhu, u can set the glBlendFunc to GL_ONE_MINUS_SRC_COLOR.
