Hi Ricardo,
you probably want to do this, without calling the ray command:
cmd.png("image.png", 640, 640, dpi=300, ray=1)
Also, your ray command sets antialias=300 and angle=-1, which I guess was not
your intention. I'm not getting a segmentation fault with the latest SVN code
using your command, though. Do you have any volume representation? Volume is
not fully supported with ray tracing.
Cheers,
Thomas
