Hi, I'm trying to plot an outline of an arbitrary 3D shape using matplotlib's plot_surface, and I wanted to ask if any one has any ideas as to how to do it. Here's the beginnings of a simple example:
# create a grid resolution = 10 xs = np.linspace(-1,1,resolution) ys = np.linspace(-1,1,resolution) zs = np.linspace(-1,1,resolution) X,Y,Z = np.meshgrid(xs, ys, zs) #Then we can calculate the square of the distance of each point to the center: W = X**2 + Y**2 + Z**2 # Let's see which points are within a certain radius: C = W < 1. # this can be used to create a point-cloud x = X[C] y = Y[C] z = Z[C] From this I tried a lot options, the best being to do some XOR operations on the array C to get a list of points which are on the surface of the sphere. My question is, can anybody see a reasonable way to plot this surface using mplot3D? Of course plotting a sphere can be done using spherical coordinates, but that defeats the purpose of this example :) This is just a simplification as the application is actually to draw 3D contours (i.e. shapes, rather than iso-lines) of a three-parameter probability distribution.
