# How to calculate BaryCentric?

Posted on 2001-08-28

Is there some formula to calculate the BaryCentric a,b & c values of a 3-D triangle?

I want to calculate this for a point P on the plane of the 3-D triangle. Is it then possible to calculate a point P' from a "warped" 3-D triangle so that P' is proportianally in the same place inside the "warped" triangle as P inside the original triangle?

Basically I want P' must "look" to be in the correct place as the triangle gets "warped" and I thought Barycentric coordinates would be the best, but the stuff on the internet is quite hairy to read through!
