I'm getting close to cutting over to my new PC.

I just need to install the graphics card, but I am testing with the built-in
Intel graphics first.

It seems relatively fast ATM.

Does anyone have suggestions for challenging (not earth stopping) code which
could be considered for benchmark comparison across my current PC (core2
2.53 GHz 4GB SSD Ion Graphics), my new one (i7 quad 3.4-3.9 GHz 16GB RAID
SSD Intel Graphics), and ditto plus a medium range Graphics card (ASUS
GeForce GTX 750 Ti Strix 2GB).

Perhaps I could build a consistent set of performance test code for use
across versions. Code exploiting different aspects of OpenSCAD internals. ??

I'm not talking about many hours of rendering, but ~2 hours max could work
if it was recommended for a particular a reason.

I'm starting with some of the examples. (#24)

The projector plate in this project takes 20-30 minutes to render on my Ivy
Bridge i7 laptop: https://github.com/hyperair/projector-mount/

Lots of minkowskis and hulls from using Andrew's generalized fillet library.

Hi, I suspect you are using a new MCAD.

I've managed to map most of it to the old MCAD, but I can't find the
'conv2D_polar2cartesian()' function.
Where can I find it?

Hmm, it might not have been added yet. It looks like gears.scad has a
polar_to_cartesian() function that works the same though.

Otherwise you could just use this:

function conv2D_polar2cartesian(x) = [ x[0]*cos(x[1]) , x[0]*sin(x[1]) ];
