View Full Version : Texture mapping in orthographic parallel view

03-20-2003, 01:01 AM
i have a question simple but difficult to explain.
To begin i am using blending of this type
glBlendFunc(GL_ONE, GL_ONE)
and i render a texture on a quad using parallel view and after i have rotate this quad of 90 around x. I expect to see a single line that is the sum of all texture's line.
Is this correct?

Thank you.

no pixels get rendered if you view a polygon like that.

At least if the driver is conformant.

If pixels _did_ get rendered, what make you think a sum of the texels would result?
