multiplyByPointAsVector
fun multiplyByPointAsVector(matrix: Matrix4, cartesian: Cartesian3, result: Cartesian3): Cartesian3(source)
Computes the product of a matrix and a Cartesian3. This is equivalent to calling Matrix4.multiplyByVector with a Cartesian4 with a w component of zero.
const p = new Cartesian3(1.0, 2.0, 3.0);
const result = Matrix4.multiplyByPointAsVector(matrix, p, new Cartesian3());
// A shortcut for
// Cartesian3 p = ...
// Matrix4.multiplyByVector(matrix, new Cartesian4(p.x, p.y, p.z, 0.0), result);Content copied to clipboard
Return
The modified result parameter.
Parameters
matrix
The matrix.
cartesian
The point.
result
The object onto which to store the result.
