Usage

myVec3d.dot(vec3d:Vector3d) : Number

Parameters

• vec3d A Vector3d to dot product with myVec3d.

Returns

A number.

Description

Method; returns the dot product of myVec3d with vec3d. This is equlivalent to

var d = myVec3d.x*vec3d.x + myVec3d.y*vec3d.y + myVec3d.z*vec3d.z;

Note that myVec3d.dot(vec3d) == vec3d.dot(myVec3d). 

Example

var vec1 = new Vector3d(4, 5, 6);
var vec2 = new Vector3d(7, 8, 9);
trace(vec1.dot(vec2)); //displays 122
