Re: [PanoToolsNG] Canal-View: a 553-pano traverse of the Grand Canal
Thanx to you all!!!
still did not try with Lucid...
Viewer tecnology is the limit, right now.
I've a triple-sli mainboard and I could try a triple nvidia 280 if I
had some money for video cards.
The other pc is a 3ghz quand core w/ ati 4870 with 1gb, xp 48bit, 8gb
ram, 4xraid0... and is the reason I got all the panos stitched in one
