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.
