TriMesh polygon display #149

Closed kcpevey closed 6 years ago

kcpevey commented 6 years ago

I believe TriMesh displays on the drawing tools by drawing the individual triangles as polygons (edges, not datashading). Is that correct?

How/where is that happening in the code?

Or... are just the edgepaths draw as three separate lines? That would be more computationally efficient.

Could you clarify which example you're referring to here or is this just a general question? If you plot a TriMesh directly it will indeed be rendered as a collection of nan separated paths, which I'm fairly sure is about as efficient as it's going to get. You can see how the TriMesh gets expanded into a set of lines in the TriMesh.edgepaths property.

That answers my question. TriMesh is drawn by drawing each element as 3 lines, NOT a polygon.
