I have my own 2D face image and 3D OpenGL face model with triangle polygon mesh(I also have all the vertex coordinate).
How can I map my face texture on 3D model?
I wonder if I have to segment my face image to every pieces of triangle mesh and map each piece on every mesh in 3D model.
if I have to do that, in my opinion, this operation will take too much times.
Plz~~ tell me how to map 2D face texture on 3D model
thank you for your time…^^
