Detailed Description

Ability to move VDB Points using a custom deformer.

Author
Dan Bailey

Deformers used when moving points are in world space by default and must adhere to the interface described in the example below:

struct MyDeformer
{
// A reset is performed on each leaf in turn before the points in that leaf are
// deformed. A leaf and leaf index (standard leaf traversal order) are supplied as
// the arguments, which matches the functor interface for LeafManager::foreach().
template <typename LeafNoteType>
void reset(LeafNoteType& leaf, size_t idx);
// Evaluate the deformer and modify the given position to generate the deformed
// position. An index iterator is supplied as the argument to allow querying the
// point offset or containing voxel coordinate.
template <typename IndexIterT>
void apply(Vec3d& position, const IndexIterT& iter) const;
};
Note
The DeformerTraits struct (defined in PointMask.h) can be used to configure a deformer to evaluate in index space.
