A transformation analysis of 3D virtual object for projection mapping
The transformation relationships between real-world and 3D virtual objects are analyzed for projection mapping. Projector coordinates systems and OpenGL vertex transformation model are examined. Mainly, we analyzed lens distortion model and its inverse model, and proposed shader code for it.
