Hello everyone...
I was wondering if anyone has found a way to flip an object using J3D...
The geometry is just a triangle array that I create from a indexed trinagle
set from a VRML file (home made loader), I read the normals from ths file as
well... I would like to just flip that object over the x coordinate. As
far as flipping the geometry it seems to work fine by the just switching the
sign on th ex coordinate of each points... However there is a problem with
the normals... I can't figure out how to have the normals follow. If leave
them as is of course it is a problem because they are facing the wrong
way... I try to change the sign of the x coordinates on the normal vector
as well (something that made sense to me) and it seems to be working only
partialy. Using negative scaling factors doesn't seem to do the trick
either.
Does anyone has ever flipped an object in J3D or found a way ti achieve
similar results. Maybe I am just poor at linear algebra.
Could that be a new transform made available in the next verosin of J3D as
well?
