Subject: Tip + SGI speed
All :)
Just a small tip there:
I'm doing a mine scene, using a displacement mapped polygon mesh (about
20,000 polys) for the mine walls.
The reason I keep the mesh displaced in layout and don't 'save
transformed' is I need the mesh relatively straight, if I want to add
side tunnels. This leads me to the problem:
It takes approx. 10 seconds to get a wire frame in Layout (
*** Allen: Hidden line removal in Layout, please!!! ***
), even when I hide objects or draw them as points only. Sometimes I need
to know where things are so other objects could move in relation to them,
and it gets very slow. So -
I use a WHITE BOARD MARKER to draw on the screen the stuff I want from the
wireframe, then work in boxes until the next major step. This saves many
minutes of waiting for the scene to redraw. The marker wipes off easy and
leaves no trace.
... And a 'small' query - Does the SGI 4.0 renders faster than the DEC
ALPHA, and on what configurations?
