Procedural implicit surfaces are a popular representation for shape modeling. They provide simple framework complex geometric operations such as Booleans, blending and deformations. However, their editability remains challenging task: the definition of is purely implicit, direct manipulation cannot be performed. Thus, parameters model often exposed through abstract sliders, which have to nontrivially created by user understood others each individual modify. Further, these sliders needs set one achieve desired appearance. To circumvent this laborious process while preserving editability, we propose directly manipulate surface in viewport. We let naturally interact with output shape, leveraging points on co-parameterization design specifically surfaces, guide parameter updates reach appearance faster. leverage our automatic differentiation procedural propagate interactions made viewport themselves. further solver that uses information an intuitive smooth workflow. demonstrate different editing processes across multiple shapes would tedious tuning sliders.
