Detailed Description

template<typename Sampler, typename TransformerType>
class openvdb_houdini::GridResampleOp< Sampler, TransformerType >

GridResampleOp is a functor class for use with UTvdbProcessTypedGrid() that samples an input grid into an output grid of the same type through a given transform.

The output grid's transform is unchanged by this operation.

Example:
namespace {
// Class that implements GridResampler's Transformer interface
struct MyXform
{
bool isAffine() const { ... }
openvdb::Vec3d transform(const openvdb::Vec3d&) const { ... }
openvdb::Vec3d invTransform(const openvdb::Vec3d&) const { ... }
};
}
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 transform and metadata.
GridPtr outGrid = inGrid.copyGridWithNewTree();
// Resolve the input grid's type and resample it into the output grid,
// using a trilinear sampling kernel.
GridResampleOp<openvdb::tools::BoxSampler, MyXform> op(outGrid, MyXform());
