Opengl image warping
Web11 de jul. de 2013 · openFrameworks smallfly July 10, 2013, 9:45pm #1 Hi, 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. Although I achieved image rendering using OpenGL, I don't know how to warp an image. An warpable example I want is ( Reference ): But a picture I got is: As I know, this problem is related to perspective correction mapping. But I don't know about that well. Here is my source code.
