getLength
-
Vec3.getLength() Returns the length of the vector (sqrt(x^2 + y^2 + z^2)).
Return type: number
getLengthSquared
-
Vec3.getLengthSquared() Returns the squared length of the vector
Return type: number

-
Vec3.fromArray(arr) Arguments: - arr (
ArrayLike) – None
Creates a new Vec3 instance from the first 3 elements of the given array.
Return type: Vec3 - arr (

Vec3.transformPoint(p, matrix) Arguments: Returns a new vector with the given vector transforms as a point.
Transforms the vector as a point by multiplying it with the given matrix. This will both rotate and translate the vector p. Assumes the matrix m doesn’t contain any perspective projection.
Return type: Vec3
static transformVector
-
Vec3.transformVector(p, matrix) Arguments: Returns a new vector with the given vector transforms as a vector.
Transforms the vector as a vector by multiplying it with the given matrix. This will only rotate the vector. The translation part of the matrix will be ignored. Assumes the matrix m doesn’t contain any perspective projection.
Return type: Vec3
