There's no need to involve rotation matrices (or any kind of matrices at all) for basic ray tracing, it's just a basic exercise in vector arithmetic.

- Kednicma 6y agoThere's no need to differentiate between vectors and matrices in this sort of work, other than as shorthand for dimensional information. [0] is another example of a ray-tracing tutorial which, by virtue of using GLSL, doesn't draw a hard line between matrices and vectors.
