Given an irregular triangle mesh with V and F as the no. of vertices and faces respectively and an image. How to map image (texture) to Mesh(V,F) ?
There are other answers but they are using meshgrid. Can I do this without using meshgrid as my Mesh is irregular.

But how are you plotting these points? Mesh(V,F) is not a function in MATLAB.

Read about triplot, trimesh, trisurf and patch.

By default, trimesh returns a patch object. MATLAB does not seem to support texture mapping on the patch object. See this FEX package: https://www.mathworks.com/matlabcentral/fileexchange/28106-texture-patch, which uses the surface object to create the patches which support texture mapping.
