Here is a link to the reference image I'm using:
http://digitalstratum.com/images/tron/lightcycle_all_sides.jpg
Note the front wheel. On the right you see some blue between the black
inner part of the wheel and the edge (I call this the rim), which is
missing by the time you get to the left side of the wheel due to the
perspective. Also, the center point of the rear wheel is actually in
line with the rear of the body, but it looks slightly set-in. The
bottom view also shows what looks like the rear wheel intersects the
body and does not fit in the wheel-well, but that's not really the case,
it does fit.
It is these kinds of errors that makes it particularly difficult to
determine several things:
1. Overall length of the lightcycle.
2. The true curvature of the canopy.
3. The size and placement of objects.
I was hoping there would be some way I can adjust for the perspective as
I move away from the center (where ever that happens to be...) I think
the perspective is worse from side-to-side than top-to-bottom, but it's
hard to tell.

2D images can be reworked in Photopaint/shop to have no perspective showing
in the verticals and with some images it is possible to go some way to also
remove this in one horizontal direction. Maybe post us one of these problem

To remove perspective in all aspects of a comprehensive 2D picture ... it's
probably best to start again and remodel in RS ... or live with it. Maybe
minimise it with (non) lighting, blur it, etc.

Subject: Compensating for perspective
I have an image I'm using as a reference to accurately reproduce a model
from (yes, still the lightcycle, but I'm very much an absolute
perfectionist.) The problem is that every known image was rendered with
perspective, which may have been the only option in 1982. When trying
to size objects and place them properly, the perspective causes an error
which makes it difficult to get things like the curves and angles
correct. Is there any way to compensate for the perspective in the
original 2D image?
Thanks,
Matthew
