Constructor & Destructor Documentation

CachedDeformer ( Cache &  cache )

explicit

Cache is expected to be persistent for the lifetime of the CachedDeformer.

Member Function Documentation

void apply	(	Vec3d &	position,
		const IndexIterT &	iter
	)		const

Retrieve the new position from the cache.

void evaluate	(	PointDataGridT &	grid,
		DeformerT &	deformer,
		const FilterT &	filter,
		bool	threaded = true
	)

Caches the result of evaluating the supplied point grid using the deformer and filter

Parameters

grid	the points to be moved
deformer	the deformer to apply to the points
filter	the point filter to use when evaluating the points
threaded	enable or disable threading (threading is enabled by default)

void reset	(	const LeafT &	leaf,
		size_t	idx
	)

Stores pointers to the vector or map and optionally expands the map into a vector

Exceptions

IndexError

if idx is out-of-range of the leafs in the cache
