George,
I
believe this alone is not sufficient, there is one more catch. Consider two
triangle parallel to each other but lying on two different planes(say
with different z- depth). The below said algorithm will fail in this case since
the angle between these triangles will be zero degrees but actually they are
not on a single plane.
Thanks
Shyam

[JAVA3D] AW: [JAVA3D] Determining the triangles lying on a plane
Hello Shyam !
you
could calculate the angle between the normal to the triangles in question ( one
at a time of course) and the normal to your reference plain. If this angle is
within the tolerance you set then the triangles are on the "same"
plane.
regards,
George
