Hi,

I'm having a problem with skeleton bones. I would like to find a perpendicular to a bone.

Since I only have 2 points (pivot point and end point) what is the correct method to get a perpendicular (starting from pivot point in any direction).

I thought I could use a cross product to get a normal (which is perpendicular) but for this I need a third point, and I don't see which.

Or is there any other way ?

Thanks,

Yarp
