Wireframe colored mesh

Hi,

I’m following up on an answered stack overflow thread:

http://stackoverflow.com/questions/24909256/how-to-obtain-3d-colored-surface-via-python/26026556#26026556

They show how to create a colormap for a wireframe plot. I noticed that this solution fails when the X and Y data are not the same shape. This inherently comes down to _segments3d being a 3 dimensional array when X, Y are the same dimension, but a 1D array when X,Y are different dimensions.

So for example, a set of 10 curves, each with 100 points would have the dimensions:

X —> 10

Y —> 100

Z ----> 10 x 100

I’ve tried hacking on this all day and just can’t get a solution to bypass the numpy ravels() and rolls()!

Any ideas?

Thanks

I always wonder why people go through such lengths to implement such features, but never bother to offer them back into the mainline code or at least suggest such a feature. Think you could make a feature request for this on github? I bet I could figure out how to integrate it into the mesh code without the need for any hacks if I spend a free moment on it.

Agreed. I will do so, thanks. If you are able to figure it out, I would be super grateful. I must have spend 5 hours beating my head over this…

I’ll fill it out tonight.
