math.triangle.interp
Syntax
- f = math.triangle.interp(v1,f1,v2,f3,v3,f3,vIn)
Return interpolated value at vIn based on triangle interpolation. The triangle vectors are 2D vectors with a number associated with each vertex. The interpolated value is based on fractional areas of opposite triangles. The point vIn must fall within the triangle.
Returns: f - interpolated value
Arguments: v1 - 2D triangle vertex
f1 - number associated with v1
v2 - 2D triangle vertex
f2 - number associated with v2
v3 - 2D triangle vertex
f3 - number associated with v3
vIn - 2D interpolation point
