You can wrap any image or texture on the surface using the
mesh.addTexCoord( texPoint ) function. Here
texPoint is of the
ofPoint type. It is a 2D point that should lie in range [0, w] × [0, h], where w × h is the size of the image that you want to use as a texture. Remember that you should call this function as many times as you call the
mesh.addVertex() function so that all the vertices will have texture coordinates.
During rendering each primitive of the mesh (whether triangle, line, or point depends on the mesh's mode), the texture coordinates of each rendered pixel will be calculated by OpenGL as interpolation of texture coordinates of the primitive's vertices. Resulting texture coordinates for the pixel are used for the pixel's ...
