Detailed Description

template<typename GridT = Vec3fGrid, bool Staggered = false, size_t SampleOrder = 1>
class openvdb::v9_0::tools::VelocityIntegrator< GridT, Staggered, SampleOrder >

Performs Runge-Kutta time integration of variable order in a static velocity field.

Note

Note that the order of the velocity sampling is controlled with the SampleOrder template parameter, which defaults to one, i.e. a tri-linear interpolation kernel.
