Texture Mapping onto the Mesh

Hi,

   Given an image and a mesh, how do I map the image on to the mesh by 
matlab assumed that the texture mapping is known? 
The things are known:
   the 3D points
   the triangular mesh
   the image
   the correspondence between the image pixels and points

   Is there any commands in MATLAB doing the texture mapping? Please 
give me a short example. Thank you for your help.

Regrd,
fred
