That is not inverted perspective but orthographic projection. Jsc3d's model
transformation is based on orthographic projection (which is also adopted in
many CAD applications) in which no perspective is applied and the projected
length of an edge will not change when it moves along the viewing direction.
This is different with how human eyes actually work, and thus it causes visual
error especially on strip objects.
Jsc3d does not support other projection methods (such as perspective projection
which produces more natural result for our eyes) at this moment. Please refer
to http://en.wikipedia.org/wiki/Graphical_projection for details of graphic
projections.

for the users interested in having a perspective projection for thier scene i
will come asap with a final release.
For now I uploaded here just a simple demo based on JSC3D 1.6.5 having these
changes:
1. perspective projection
2. transparent background for the scene
Because I didn't wrote the code very nice and I just altered the current code
of the jsc3D I'll come back in the next days with an updated version with a
better quality code and more refined.

Hi!
Thanks for the submitted project.
Unfortunately, your example with 3DS model does not work.
I tried to open in IE-11 and Chrome (Windows 7).
Then I tried your version jsc3d.js to models OBJ.
Works, but the quality is not satisfactory.
With interest forward to the final release.
Regards, Valery.

Thank you for the submitted contribution. I've been checking back time to time
the last few months and interested in your work on perspective projection.

transparent.... any solution for making the background transparent?

This feature is not supported by r1.6.5. You could try the latest version
instead. Please get it from the repository.
