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
gridthe points to be moved
deformerthe deformer to apply to the points
filterthe point filter to use when evaluating the points
threadedenable 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
IndexErrorif idx is out-of-range of the leafs in the cache
