Hiya,
I've been trying to get the code from the following
tutorial to work
in a GLSL patch in Quartz Composer.
http://www.ozone3d.net/tutorials/vertex_displacement_mapping_p03.php
I understand that vertex displacement is only
supported on certain
graphics hardware (ie newer nvidia cards), but I
wonder if the
attached patch works for anyone. I don't get an error
when I run it on
my G5 (with an nvidia GeForce 7800 GPU), but neither
does it actually
appear to work. It could be I'm making some very
stupid and obvious
mistake in the code, as I just copy-pasted it from the
page. Anyone
any ideas?
My test QTZ file can be downloaded here;
http://158.223.20.36/temp/Vertex_Displace_Test_04-11-07.qtz
If some could take a look at it, I'd be very grateful.
Cheers,
alx
