Do a reload. Just to show you what "HIGH QUALITY" rendering
means.
It's still the same scene - just the border of the box a
little higher, the glass better visible and sized to 600x300
(to better fit on the page). This time rendered with a
sampling rate of 5^2 per pixel (so per pixel 25 eye rays are
shot into the scene). Including all shadowing, transparency
and reflection a total of over 20 million rays have been
traced (for a picture with 180,000 pixels)!
Those pictures are CPU killers. A 333 MHz Celeron needs 20
minutes to finish that one.
Remember, it's a 100% virtual picture. Not one single detail
is from a scanned photo or the like.
