Triangle::Point
Syntax
float4 Triangle::Point(const float3 &uvw) const; [4 lines of code]float4 Triangle::Point(float u, float v, float w) const; [4 lines of code]
Returns the point at the given barycentric coordinates.
This function computes the vector space point at the given barycentric coordinates.
Parameters
const float3 &uvwThe barycentric UVW coordinate triplet. The condition u+v+w == 1 should hold for the input coordinate. If 0 <= u,v,w <= 1, the returned point lies inside this triangle.
Return Value
u*a + v*b + w*c.
Syntax
float4 Triangle::Point(const float2 &uv) const; [4 lines of code]float4 Triangle::Point(float u, float v) const; [7 lines of code]
These functions are an alternate form of Point(u,v,w) for the case when the barycentric coordinates are represented as a (u,v) pair and not as a (u,v,w) triplet.
This function is provided for convenience and effectively just computes Point(1-u-v, u, v).
Parameters
const float2 &uvThe barycentric UV coordinates. If 0 <= u,v <= 1 and u+v <= 1, then the returned point lies inside this triangle.
Return Value
a + (b-a)*u + (c-a)*v.
