Hello everyone.
I was wondering if there was a method to rotate an already rendered scene.
I thought of doing glReadPixels() followed by glRotate() followed by glDrawPixels().
But this will not work right?
I mean there is no point in giving glRotate() after rasterization right?
Is there any way i can rotate the scene? without acually drawing it again.(i mean not rendering it again)
What are you trying to do? Rasterizing your geometry will put stuff onto a 2D target. Do you want to rotate that 2D target in your viewport after the fact?
If so, render your normal scene to a texture then you can just rotate that texture around using glRotate.
