Member Function Documentation

template<typename GridT >

__hostdev__ Vec3<ValueType> nanovdb::BoxStencil< GridT >::gradient ( const Vec3< ValueType > & xyz ) const

inline

Return the gradient in world space of the trilinear interpolation kernel.

Parameters

xyz	Floating point coordinate position.

Warning: It is assumed that the stencil has already been moved to the relevant voxel position, e.g. using moveTo(xyz).

Note

Computed as partial derivatives of the trilinear interpolation kernel: v000 (1-u)(1-v)(1-w) + v001 (1-u)(1-v)w + v010 (1-u)v(1-w) + v011 (1-u)vw

v100 u(1-v)(1-w) + v101 u(1-v)w + v110 uv(1-w) + v111 uvw

Definition at line 374 of file Stencils.h.

template<typename GridT >

__hostdev__ ValueType nanovdb::BoxStencil< GridT >::interpolation ( const Vec3< ValueType > & xyz ) const

inline

Return the trilinear interpolation at the normalized position.

Parameters

xyz	Floating point coordinate position. Index space and NOT world space.

Warning: It is assumed that the stencil has already been moved to the relevant voxel position, e.g. using moveTo(xyz).

Note

Trilinear interpolation kernal reads as: v000 (1-u)(1-v)(1-w) + v001 (1-u)(1-v)w + v010 (1-u)v(1-w) + v011 (1-u)vw

v100 u(1-v)(1-w) + v101 u(1-v)w + v110 uv(1-w) + v111 uvw
