hey robert -
The distinguishing features of one and two point perspective drawings
are that all horizontal lines diverge to one or two vanishing points
(both on a horizon line), and that all vertical lines are vertical (and
parallel).
To set this up in XSI just link the y position of the camera interest to
the y pos of the camera.
hope that helps,
mel

Subject: classic vanishing point perspective vs. perspective and
perspective view
hi,
i have the drawing which was done based on diagrams of elevations. this
is perspective drawing, which from the very beginning looks quite
strange, although when you put the elevation drawings it in educational
software (Cabri Geometry II Plus) calculating (among many others)
perspective distortion everything seems to fit.
i modeled this set of objects using the measurements and tried to match
it in perspective and camera view. no luck. i did rhotoskoping many
times before, although i've never used drawings. only photographs or
movie/video frames.
my question:
is the one or two vanishing point perspective distortion different than
this used by the XSI's camera and perspective view? what could be the
reason i cannot rotoskope this object on the picture even if it was
drown according classic perspective rulles?
thanks in advance. <rs>
