barycentricCoordinates
external fun barycentricCoordinates(point: Cartesian3, p0: Cartesian3, p1: Cartesian3, p2: Cartesian3, result: Cartesian3? = definedExternally): Cartesian3?(source)
Computes the barycentric coordinates for a point with respect to a triangle.
// Returns Cartesian3.UNIT_X
const p = new Cartesian3(-1.0, 0.0, 0.0);
const b = barycentricCoordinates(p,
new Cartesian3(-1.0, 0.0, 0.0),
new Cartesian3( 1.0, 0.0, 0.0),
new Cartesian3( 0.0, 1.0, 1.0));Content copied to clipboard
Return
The modified result parameter or a new Cartesian3 instance if one was not provided. If the triangle is degenerate the function will return undefined.
Parameters
point
The point to test.
p0
The first point of the triangle, corresponding to the barycentric x-axis.
p1
The second point of the triangle, corresponding to the barycentric y-axis.
p2
The third point of the triangle, corresponding to the barycentric z-axis.
result
The object onto which to store the result.
