I have two geometries (same cartilage sample). The first geometry is the cartilage before being exposed to a fluid, the second geometry is the same cartilage a has diffused in it thus it has swollen and its geometry has changed. The surface and bottom of both geometries must match. How can I assign landmarks manually over the surface and the bottom of both? That is two set of landmarks for the registration to take place?
But this doesn't work when a surface is curved like a ball. You triangulate these projections of the vertices on x-y plane, but some obtained triangles are not the projections of the real triangles on the surface.
Amirali: Try clicking on the figure to select it, then pressing a key on the keyboard. The surface mesh example is given in the demo. The code is:
surf(Z, sc(Z, 'hicontrast'), 'edgecolor', 'none');
where Z is the heightmap.
