Problem

in the trisurf examples, the .triangles attribute is used for the plotting:

tri = mtri.Triangulation(u, v)

# Plot the surface.  The triangles in parameter space determine which x, y, z
# points are connected by an edge.
ax = fig.add_subplot(1, 2, 1, projection='3d')
ax.plot_trisurf(x, y, z, triangles=tri.triangles, cmap=plt.cm.Spectral)

but the docs only document triangles as an input parameter into the constructor:

Suggested Improvement

Minimally the class should be cross linked against the trisurf example. Not sure if the fix is also document .triangles as an attribute, make it a property, or consolidate tri.get_masked_triangles() since it returns the unmasked triangles when there's no mask.
