[−][src]Module sdfu::util

Other random utilities that are helpful when using SDFs in computer graphics applications, such as estimating normals.

Structs

CentralDifferenceEstimator	Estimates the normal of an SDF by estimating the gradient of the SDF.
EstimateNormal	Estimates the normal of an `sdf` using an `estimator`.
TetrahedralEstimator	Estimates the normal of an SDF by estimating the gradient of the SDF.

NormalEstimators provide a way to estimate the normal of the SDF sdf at point p.
