multiplyByPoint
Computes the product of a matrix and a Cartesian3. This is equivalent to calling Matrix4.multiplyByVector with a Cartesian4 with a w component of 1, but returns a Cartesian3 instead of a Cartesian4.
const p = new Cartesian3(1.0, 2.0, 3.0);
const result = Matrix4.multiplyByPoint(matrix, p, new Cartesian3());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.
