Tyler Bay shows how to create a stylized smoke effect while also introducing Quaternion rotations.

CG Forge and Tyler Bay offer some insights into creating a stylized smoke effect from a standard one in Side Effects Houdini. The tutorial also introduces the concept of quaternion rotations, which is used to create the final look.

Quaternions, being a number system that extends complex numbers, might be a stumbling block for a lot of 3D users. If you are looking to learn more about quaternion rotations, his tutorial from Bay is an excellent place to start, even though it’s not a comprehensive guide.

“keep in mind that this is not a comprehensive definition of quaternion rotation -This is, however, a much more accessible place to start.”
