Practical notes on implementing derivatives

For many applications in graphics, one is confronted with the task of solving an optimization problem or solving a nonlinear system of equations. Efficient methods for solving these problems require derivatives to be available. Differentiation in numerical methods also occurs for many other reasons, such as computing forces from potential energy or computing normal and curvature information fro...
