I'm doing 3D face surface data visulization. The data is a N*3 matrix, of which the 1st column represents x of every point, 2nd represents y and 3rd represents z. I want to use point-based model. So I think the function "plot3" must be the choice. But how can I use plot3 to draw each points (x,y,z) with color determined by z so that color is propotional to surface height?
I know mesh can do that, but I dont want a mesh model. I need a point-based model so that I could do further manipulation like two point sets registration.
If any one could answer me, I would very appreciate!!
