crude 3D modelling in BELA

["James Pawson" <thedatastream@xxxxxxxxx>]

All,

I'm developing a crude method of modelling 3D objects in BELA. I'm 
simulating a multilayer PCB capacitor with circular pads and an off 
centre via and clearance hole.

The method I have used is to use LUA to draw a top cross section of 
the pads in BELAdraw. This is then divided up and cut into "vertical 
slices" by LUA, using the modified selectnode() function discussed 
earlier in http://groups.yahoo.com/group/femm/message/2163

These results are written to an array, and accessed to draw and 
simulate each slice individually. The results are added up and the 
end result is presented using a message box.

I'm at the stage now where the cross section of the pad stack 
capacitor is being sliced up and successfully drawn. This is then 
triangled and at the point where it can be simulated.

I will update when I have written more code.
questions? comments?

regards, and thanks for the help so far
James
