Is it the best way to calculate normal?

[Wodzu]

Hi,

I just want to make sure that there is no other way in Irrlicht for calculating normal other than this?

Code: Select all

 
core::plane3df(vertex[2],vertex[1],vertex[0]).Normal
 

I mean creating an object (plane3df) for calculating a normal seems a bit heavy for me. I know I could just write my own function but I wonder if there is such function by default in Irrlicht?

Thanks for your time.

core::triangle3df has also a getNormal. Or you just copy the implementation: (pointB - pointA).crossProduct(pointC - pointA);

edit: (but stack objects are not expensive anyway, so don't worry too much)

Thanks for a quicky reply!

I just like to know all my possibilities:)

Thanks again.
