Hi Phil,
I think I read once that the face of many CRT's are actually sections of
spheres (it also said Sony Trinitron CRT's are sections of cylinders). That
being said, I drew the shape of an old, kinda oval shaped TV tube in the Shaper
and lofted it along a straight path. In the Editor, I created a nice big sphere
and tesselated it with edge tension until the detail was enough to support the
size if the screen I was looking for. Then I intersected the "tube" object
dead-center with the sphere object and did a boolean intersection. After a few
trys (mostly for face detail and scale) I got what I thought was a pretty good
representaion of an old TV tube.
In the past I think I've whipped up a modern CRT screen merely by creating a 2D
grid plane with Grids.pxp, and simply bending it around 2 axes until it was
properly bulbous. The rounded edges were implied by the bezel of the monitor
mesh itself.
Hope this helps,
-Alan
