## Member Typedef Documentation

## ◆ LeafIndex

using LeafIndex = point_move_internal::LeafIndex

## ◆ LeafMapT

## Constructor & Destructor Documentation

## ◆ CachedDeformer()

CachedDeformer | ( | Cache & | cache | ) |
| explicit

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

## Member Function Documentation

## ◆ apply()

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

Retrieve the new position from the cache.

## ◆ evaluate()

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)

## ◆ reset()

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
