Detailed Description

Index mapper containing indices of a subset of a geometry.

An MIndexMapper maps indices between the full set of a geometry and the subset of indices that is affected by a deformer. If a deformer affects f.e only 1000 verts of a total of 15000 verts then the affectMap will be of size 1000 and contain the indices into the full table of points.

(

)

const

This method returns the total number of points of the geometry.

Returns

the number of points of the geometry

MIndexMapper::Index affectCount

Parameters

[in]

aid

the index into the affect list we want to remap

Returns

the remapped index or UINT_MAX (invalid) if it does not exist
