Detailed Description

template<typename Sampler>
class openvdb_houdini::GridResampleToMatchOp< Sampler >

GridResampleToMatchOp is a functor class for use with GridBase::apply() that samples an input grid into an output grid of the same type such that, after resampling, the input and output grids coincide, but the output grid's transform is unchanged.

Example:
const Grid& inGrid = ...; // generic reference to a grid of any type
// Create a new, empty output grid of the same (so far, unknown) type as
// the input grid and with the same metadata, but with a different transform.
GridPtr outGrid = inGrid.copyGridWithNewTree();
outGrid->setTransform(myTransform);
// Resolve the input grid's type and resample it into the output grid,
// using a second-order sampling kernel.
virtual GridBase::Ptr copyGridWithNewTree() const =0
Return a new grid of the same type as this grid whose metadata and transform are deep copies of this ...
bool apply(OpT &) const
If this grid resolves to one of the listed grid types, invoke the given functor on the resolved grid.
