In this section, you will learn the most common vector operations used in computer graphics. The cross product of vectors concept precalculus video. The cross product takes two vectors and returns a perpendicular vector to the plane defined by the two vectors. For instance in 2 dimensions it is not possible to find another vector which is mutually perpendicular to 2 arbitrary vectors, in 4 dimensions or greater there are many vectors which are mutually perpendicular to 2 arbitrary vectors. Sorry for being gotten a little bit mathematical this time, but it was necessary. The dot product in detail interactive 3d graphics youtube. Assuming that v1 and v2 are in the xz plane, then the direction of the cross product vector will point upwards if the rotation from v1 to v2 is counter clockwise, and downwards if the rotation is clockwise.
