How are the divergence and curl used within the graphics sphere? Are they used for shapes? Animations? Both?
Are there any other logical and possibly useful “derivatives” for vector fields that we might encounter but not specifically in this class?
Would vector fields and their derivatives (divergence/curl) be useful in simulating "force fields" on objects/bodies of objects? For example, in a gravity system simulation?
When do we care more about divergence, and when about curl?
Why do we need such concepts for vector field?
