How to know if a triangle is facing the camera?

Blitz3D Forums/Blitz3D Programming/How to know if a triangle is facing the camera?

Hi,

I've been working with Sswift normal code from the archive...

http://www.blitzbasic.com/codearcs/codearcs.php?code=976

I was hoping that with the normal of the surface, that I would be able to tell if the triangle was in view of the camera. Is this logical or am I barking up the wrong tree? Any clues would be really appreciated as Im new to all this mesh/surface/triangles/vertex business.

Cheers
