View Full Version : Here's a Weird One: Non-planar # Changes w/Model Orientation

Have a shallow bowl that has 2,760 polys in 64 segments. Polys going over the rim are more densely populated, so as to better define the rim shape with its tight curve profile, and progressively go less dense when approaching the base; both inside the bowl and outside. With the bowl sitting level, non-planars number 520. Tilt the entire bowl 17 forward, so that it tips toward the -Z direction, and the non-planars number 514. Huh?

Well, 6 of them have become "planar" by rotation on one axis. Think of an Heptagon where either 2 or 3 sides can describe it's planar orientation. Nice one :)

Well, the polys in question are not on one axis, nor are they aligned to either X, Y or Z. Further, the corresponding polys on the opposite side of the model do not change their "non-planarness". A poly is non-planar when its points are not on the same plane. No matter its orientation, if they all are not aligned with each other... well, they'r not aligned. IOW, one of these is not like the others.

I knew you were going to say that :)
