Syntax

static FVector ComputeBaryCentric2D
(
    const FVector & Point,
    const FVector & A,
    const FVector & B,
    const FVector & C
)

Remarks

Computes the barycentric coordinates for a given point in a triangle

Returns

Vector containing the three weights a,b,c such that Point = a*A + b*B + c*C or Point = A + b*(B-A) + c*(C-A) = (1-b-c)*A + b*B + c*C

Parameters

Parameter	Description
Point	point to convert to barycentric coordinates (in plane of ABC)
A, B, C	three non-collinear points defining a triangle in CCW
