Hi,

is it possible to paint only some of the triangles of a trisurf surface? I have tried to use NaN's as CData for the patches I didn't want to colour but it ended up not colouring any of the triangles at all, including the ones whose CData values weren't NaN. I'm using CData as a n x 1 matrix, with each triangle having its own value.

Thanks in advance

I’m not certain what you want to do, but one option is the alpha function, or setting the Alpha property if you want them transparent. The other option is to colour the ‘uncoloured’ faces white = [1 1 1].
