These are various tests that I've tried on the meshed butterfly image. Some of these are in 2d and some in 3d.
The most complex so far is bfly_mesh_press_zht_cyls_3D.dxf which draws the mesh with colored cylinders in 3D.  Here I am using two
different kinds of data (pressure and uplift) to inform the display. Color is the distibution in pressure and height above
the z-plane is the uplift.

I think I have mastered the data flow and manipulation... We can also include opacity, cylinder radius, and many other things
into the data accumulation.

If  bfly_mesh_press_zht_cyls_3D.dxf  is too heavy, then we might have to go with lines instead of cylinders. The same data set (perhaps with different colors, I can't remember) is in bfly_mesh_press_zht_3D.dxf

These files are approaching the limit that I can write out given my memory limitations. Perhaps I can get another factor of two "lines.."


I am not happy with the mesh yet, I will try to make it more aesthetic the next time round. Still baby steps for me.

The owls are calling.
