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. |
