gEDA-user: PCB+GL+3D (Z-coord) Eye-candy

[Peter Clifton <pcjc2@xxxxxxxxx>]

Just proof of concept stuff...

http://www2.eng.cam.ac.uk/~pcjc2/geda/pcb+gl_3d/

There isn't anything clever here.. just the same PCB+GL translucent
rendering I had before, but with a 3D virtual trackball to rotate the
viewport.

The other kludging for these demos is some code to guess at a Z-value
for various rendered layers, repeat drawing of pins + vias on each layer
etc.. this is really crying out for some better way of some extra
information in the layer stack.

Btw.. the white ellipse on the left-hand bar is my 3D trackball "sphere"
- I left it as a separate control for now.

Code is on repo.or.cz "local_customisation_no_pours" branch if anyone is
interested.


Also.. I've rebased my branches (including the more established PCB+GL
code) on PCB's git HEAD. There was also a fix for a crasher bug which
just went in, so anyone using PCB+GL might want to update. (before_pours
branch).

Best wishes,

Peter C.
