I am working on a texture mapping problem. I use vtk C++ library for my work. I have a very dense mesh with lots of vertices. I want to apply image texture to this mesh. Should I set texture coordinates for every vertex ? Or can I skip few vertices and setup the texture coordinates and still expect the texture to be set properly? Please see the image attached.
If A,B,C,D, E, F are the vertices of 4 faces in a mesh, can I set the texture coordinates only to A,C,F,D ? Will the texture drape the faces stretching equally?
