Multiply 2 vectors
Web24 apr. 2024 · A vector is defined as a quantity with both direction and magnitude. Two vectors can be multiplied to yield a scalar product through the dot product formula. The dot product is used to determine if two vectors are perpendicular to one another. On the other hand, two vectors can produce a third, resultant vector using the cross product formula. Web13 aug. 2024 · I took a vector math class about 10 years ago and could've sworn I remembered an operation that allowed me to multiply the values of a vector together like so: Vector3 v1 = new Vector3 (1, 0, 2) Vector3 v2 = new Vector3 (5, 5, 5) //Vector3 v3 = SomeVectorOperation (v1, v2) = (1 * 5, 0 * 5, 2 * 5)
