DERIV

THE BOX'S MAIN HELP:

This function computes the derivative of A with respect to B.
Deriv(A,B) = Du(A)/Du(B) + Dv(A)/Dv(B).
The result will be the same data type as A and B.
The results are only useful if both A and B are varying expressions.

A (input):

Can be a float, point, normal, vector or color.
Must be the same data type as B.
The results are only useful if both A and B are varying expressions.

B (input):

Can be a float, point, normal, vector or color.
Must be the same data type as A.
The results are only useful if both A and B are varying expressions.

OUT (output):

This function computes the derivative of A with respect to B.
Deriv(A,B) = Du(A)/Du(B) + Dv(A)/Dv(B).
The result will be the same data type as A and B.
The results are only useful if both A and B are varying expressions.
