The Cross Product – For 3D Artists

In my last “Math For 3D Artists” post, I took a look at the Dot Product which is a simple, and immediately useful for artists, especially when writing shaders.

The Cross Product however is a powerful tool in the 3D rendering pipeline responsible for a lot of triangle calculation which makes what 3D artists do, work. In this post I’m going to explore what the Cross Product enables, and a more accessible use case for artists in Shader Graph.
