IndexIter< IteratorT, FilterT > Class Template Reference

A forward iterator over array indices with filtering IteratorT can be either IndexIter or ValueIndexIter (or some custom index iterator) FilterT should be a struct or class with a valid() method than can be evaluated per index Here's a simple filter example that only accepts even indices: More...

Detailed Description

template<typename IteratorT, typename FilterT>
class openvdb::v12_0::points::IndexIter< IteratorT, FilterT >

A forward iterator over array indices with filtering IteratorT can be either IndexIter or ValueIndexIter (or some custom index iterator) FilterT should be a struct or class with a valid() method than can be evaluated per index Here's a simple filter example that only accepts even indices:

struct EvenIndexFilter { bool valid(const Index32 offset) const { return (offset % 2) == 0; } };
