Triangle::SignedArea
Syntax
float Triangle::SignedArea(const float4 &point, const float4 &a, const float4 &b, const float4 &c); [4 lines of code]Relates the barycentric coordinate of the given point to the surface area of triangle abc.
This function computes the ratio of the signed area of the triangle (point, b, c) to the signed area of the triangle (a, b, c). This is the same as computing the barycentric u-coordinate of the given point on the triangle (a, b, c).
