+3D Gradient computation. +

+Given 3 values at the 3 corners 'ci' (gouraud, uv....), this method compute the gradients Grad. The formula to compute the interpolated value according to a 3d position 'v' in space is then simply:
+ c(v)= c0 + grad*(v-V0) +

)  const
+

+   + + +

+Intersection detection with a segment. +

+You must pass the normalized plane of the triangle as parameter.

+Parameters:
+ + + + + +
p0  +is the first point of the segment.
p1  +is the second point of the segment.
hit  +will receive the coordinate of the intersection if the method returns true.
plane  +is the plane of the triangle. Build it like this: 
  CPlane plane;
+  plane.make (triangle.V0, triangle.V1, triangle.V2);
+
+
+Returns:
+true if the segement [p0,p1] intersects the triangle else false.
