#Camera Preview…
7 messages in this thread
Hello!
just a quick question…
We are going to be dropping an Architectural 3DS model into an aerial photo,
and I am wondering about the issues involved with the image size. We have the
photo scanned at 300dpi, and have resampled it down to a 100dpi version for
aiming in 3DS. However, when I go into the camera preview IPAS routine, I see
that it resized the background image. Will my camera view still be rendered at
the appropriate screen position and perspectivity on my background image if the
render resolution is different than the camera preview IPAS routine uses?
Any comments?
Thanks!

Michael,
There is a tutorial that deals specifically with match perspective and an
architectual building. Page 15 – 30 in the New features book.

Brian,
I know about the tutorial. Unfortunately, I do not have a ground level shot to
work with… It is an aerial shot from a plane. No horizon is visible (but
probably exists WAY off the top of the image). I was just looking for some
tips on how to use this feature with such a circumstance.
Any ideas?
-Mike.
I don't have any experience with the horizon being off the field of view – but
I would expect you should be able to juggle the results.
As Brian stated, the tutorial is pretty definitive – unless you have an old
copy of 3DS4 (pre c1 or c2). Make sure you've got the latest, or you will be
missing excellent info!
Thanks. We were able to fake it, but it was not a easy experience.
Unfortunately for me, we do *alot* of aerials for diagramming purposes.
I think the perspective match tool is very easy to use assuming that you have a
visible horizon line, and that it falls in the center of the image.
I am hoping that 3DS MAX has a better way…. I could see tracing converging
lines in the image to let 3DS find the Horizon itself, regardless of whether it
is in the frame or not. This would be in keeping with the improved ease-of-use
of the entire package (I am drooling as I type).
Thanks again!

Phil Miller (used to be in Autodesk Training; co-author of Inside 3D Studio)
wrote the update to the Perspective Match tutorial. I'll forward your thread
to him in case he can influence the usefulness of either the tutorial or the
product.
Nik,
Thanks very much!
