Keystone in 2d space, projection calibrate before and after
Base on this link, i can implement 2d projection calibrate to arbitrary quadrilaterals
projective Interpolation in 3d space is a little more complicate, i need to calculate 2 lines intersection point, but works
Any idea to increase the performance to this? Calculation is complex, although we can do this once if quadrilateral not change, but if quadrilateral is dynamic change, this will cost a lot.
@arturo Can we change TexCoord from ofVec2f to ofVec3f in ofVbo, this method need vec3 texcoord. right now I need to allocate VBO and VAO myself.
