#perspective trouble
9 messages in this thread
I am just now bestowing upon myself, the virtues of the 68030 card and
having a great deal of fun with Silver. After playing endlessly with
various indexes of refraction, I have managed to actually create spheres
that look like glass. Unfortunately, I cannot make my other problem go
away.
That is, I cannot get spheres which are above, below, or to one side of the
camera, to look ROUND. They always come out looking like eggs, oblong, and
not terribly round. I have tried to make sense of the manual to this end,
but alas, nothing I have tried seems to work.
I would be ever so greatful if you could point me in the right direction.
Jim, I wish all questions were this easy! You've got to adjust the focal
length of your camera. In SV, which you should be using, "normal" view is
1.5 on Z. Anything smaller is wide angle. Large values reduce the
distortion you are seeing. –Rick
Thanks! that does clear up a lot of problems. I have tried it, and it
works. Much thanks to the other chap who replied as well…your help is
much apreciated.
In my efforts to render nice pictures, I have come across two other small
problems. I seem to be unable to get sufficient ambient light…I can never
get the picture to be terribly bright naturally, such as ambient light is
supposed to do for me. I am unclear on how that is controlled. I dont have
SV yet, just turbo 3.0
My second problem is, I still cant get IFF brushes to wrap onto anything..
I have tried following the tips in the manual, but I cant even get them to
appear, let alone getting positioning correct. Is there something obvious I
am missing?
(p.s. I think you should still ship that nifty bag of marbles with your
Silver packages…I loved it when I got mine that way!)

Jim, you might consider purchasing my tape "The World of Turbo Silver." I
think I cover the brush wrapping pretty clearly there. Just remember, the
orientation of your axis must be as stated in the manual. Second, remember
to scale your axis large enough to cover the object's surface. –Rick
Rick…sounds great. I think I would like to get my hands on this tape, I
dont think that CBM Canada has one (at least our office here in Ottawa
doesnt) so could you please leave the particulars on how much, address and
particulars? Will you take visa over the phone?

Call Impulse at 800-328-0184 for all the details. CBM USA has never bought
a tape either, although I know a couple of staffers who have purchased it.

Rick..
I havent even tried this number, but I am willing to bet dollars to
donuts that it doesnt work in Canada. Can you give me the local access
number please?

I have had some luck when I consider the value in the "focal length"
position of the Camera requester (F5) to be the actual camera focal length
times 10. So a 550 in that spot coincides with a 55mm focal length. I had
to then move the camera somewhat, but overall, it lends a measure of
consistency to the process. I was not paying much attention to the
viewpoint values you mention, Rick, but it occurs to me now ( a light!)
that that is the viewpoint offset from the actual camera icon in the editor
window. Amazing! I'm sure glad I spend the dough to hang around here, I
absorb alot of good info! Scott
