[−][src]Struct sdfu::util::TetrahedralEstimator

pub struct TetrahedralEstimator<T, V> {
    pub eps: T,
    // some fields omitted
}

Estimates the normal of an SDF by estimating the gradient of the SDF.

The gradient is estimated by taking four samples of the SDF in a tetrahedron around the point of interest. By doing so, it only needs to take four instead of 6 samples of the SDF, like the CentralDifferenceEstimator does, so it is slightly faster. However, it only works for 3d SDFs and it is slightly less robust than the traditional way.
