Functions

template<class GridType >
void sdfToFogVolume (GridType &grid, typename GridType::ValueType cutoffDistance=lsutilGridMax< GridType >())
 Threaded method to convert a sparse level set/SDF into a sparse fog volume. More...
 
template<class GridOrTreeType >
GridOrTreeType::template ValueConverter< bool >::Type::Ptr sdfInteriorMask (const GridOrTreeType &volume, typename GridOrTreeType::ValueType isovalue=lsutilGridZero< GridOrTreeType >())
 Threaded method to construct a boolean mask that represents interior regions in a signed distance field. More...
 
template<typename GridOrTreeType >
GridOrTreeType::template ValueConverter< bool >::Type::Ptr extractEnclosedRegion (const GridOrTreeType &volume, typename GridOrTreeType::ValueType isovalue=lsutilGridZero< GridOrTreeType >(), const typename TreeAdapter< GridOrTreeType >::TreeType::template ValueConverter< bool >::Type *fillMask=NULL)
 Extracts the interior regions of a signed distance field and topologically enclosed (watertight) regions of value greater than the isovalue (cavities) that can arise as the result of CSG union operations between different shapes where at least one of the shapes has a concavity that is capped. More...
 
template<class TreeType >
TreeType::template ValueConverter< char >::Type::Ptr computeEnclosedRegionMask (const TreeType &tree, typename TreeType::ValueType isovalue, const typename TreeType::template ValueConverter< bool >::Type *fillMask)
 Constructs a memory light char tree that represents the exterior region with +1 and the interior regions with -1. More...
