I want to implement CNN for 3D Mesh structure having Vertex, Vertex Color and Face

I want to perform classification over 3D mesh structures(.obj) labeled files. I have vertex (N3) , vertex color(N4) and face (M*3) in numpy array format for all meshes. Here N is total number of vertexes and M is total number of faces.
I have a question
how can I feed multiple mesh objects with vertex, vertex color and face to CNN model and get prediction on the basis of color and shape of mesh.
I believe that community will help me in resolving this problem. Thanks in advance.
