Description

While there are a few common variants to restrict a value to a range, such as a clamp function and a smoothstep, they commonly have regions with vanishing gradients outside the target range. This makes these methods non-optimal for differentiable programming. Thus, we have built a better “clamp” using periodic functions, chosen to be efficient to compute compared to similar alternatives. Furthermore, this extends differentiability towards the position of the boundaries.
