This work proposes a method to directly manipulating of procedural implicit surfaces through mouse strokes in the viewport. We estimate an update of the procedural parameters of the implicit surface that matches the user intent thanks to the auto-differentiation of an augmented version of the implicit function.

pEt is a direct manipulation tool for editing the parameters of procedural vector patterns. Users selects some points in the viewport and expresses a transformation using a mouse movement. The parameters are optimized as the user performs the movement using a gradient-descent based approach.

BoolSurf ports boolean set operations to the manifold settings. It computes boolean operations between geodesic shapes on surfaces of any genus and with open boundaries, supporting self-intersecting and complex designs.

pOp is a practical method for estimating the parameters of vector patterns, that are formed by collections of vector shapes arranged by an arbitrary procedural program. Program parameters are optimized by automatically differentiating the signed distance field of the patterns.
