[Openmcl-devel] differences from os10.5.... to 10.6...

[Arthur Cater]

A month ago I was having trouble with demos (my own and Neil Baylis's) that were not running properly
for some folk. I wrote to the list as copied below.

Then my Darwin-64's disk failed. It was replaced for me while I was on holiday.

So I took the opportunity of having the Leopard OS installed first, and tested the demos.
Then I installed the Snow Leopard OS, and tested again. I used ccl 1.5-r13651  (DarwinX8664)
in both cases. The demos did work properly under Leopard, and they do not work properly
under Snow Leopard. Therefore I conclude that the problem is something to do with versions
of MacOS and not the graphics card or other hardware - though conceivably with the driving of them.

If somebody with insight into Leopard/SnowLeopard differences could have a look at these demos,
which I attach, I would be most grateful. (I first made a small change to Neil Baylis's demo to make it
use cg-floats).
