I want to apply a texture to a 2D mesh, in order to do some projection mapping on an irregular surface. Something similar to what can be done in Mad Mapper
I made a while ago a mapping addon to do some simple mapping. For example, to correctly warp quad using homography.
But so far I’m unable to find the way to correctly map a 2D grid / mesh. If I approach this by using homography on each ‘cell’ of the grid I get the following result:
You can see that the chessboard texture does not correctly continue between the cell #2 and #4.
I searched the forum and found an old post describing the same issue ( http://forum.openframeworks.cc/t/quad-warping–homography-without-opencv/3121/7 ) but there is no reply to it.
Is homography on every quad/polygon forming the grid the correct way to do this?
