Apology Was: Image plot on back wall

I have to offer my sincere apologies to RSI for this
and other disparaging comments I may have made about
their object graphics documentation.
As it happens, their Show3_Object demo *does* work
and it is in fact possible to use 2D images as texture
maps on polygon objects. They just don't work on
*my* machine when I have the object graphics
preferences set to "Hardware" rendering.
Apparently my Number Nine Visual Technology
Revolution IV 3D OpenGL Accelerated graphics
card with 33 MByte of SDRAM, which I paid a
LOT of money for, ain't doin' what it says
it's doin'. :-(
Anyway, if I switch to Software rendering I
see exactly what the good folks at RSI have been
insisting I should have been seeing all along.
My sincere apologies to anyone whose feelings I hurt.
P.S. Let's just say I'm gonna be raggin' the folks
at Number Nine this afternoon. :-(
