I just wanted to post some screenies of some progress I've made on rendering and viewing geometries in 3D in Avalon. Eventually I will provide some code and write about what I learned about 3D meshes and triangle vertices, but for now it's just some screen shots.

I basically experimented with drawing a polygon on a plane. I started with a simple octagon, but then decided to stretch out some of its vertices to see if I could render something more "unique" (e.g. like a state or city boundary). This first shot is an overhead view looking down on the polygon. You can see the X and Z axis alongside it:

Avalon provdes the ability to draw 3D geometries within a Viewport3D object. You can then view the geometries within the Viewport3D with a Camera. The next shot is the same polygon in the same position but with the camera moved into the positive X, Y, and Z space:

And another image in the negative X, positive Z, and positive Y space:

Getting this basic exercise to work was very, very simple but only after I understood what a triangle mesh is.
