Finds the active values and tiles in a tree that intersects a bounding box. Methods are provided that count the number of active values and tiles, test for the existence of active values and tiles, and return a list of the active tiles that intersect a bbox. More...

Functions | |
| template<typename TreeT > | |
| bool | anyActiveValues (const TreeT &tree, const CoordBBox &bbox) |
| Returns true if the bounding box intersects any of the active values in a tree, i.e. either active voxels or active tiles. | |
| template<typename TreeT > | |
| bool | anyActiveVoxels (const TreeT &tree, const CoordBBox &bbox) |
| Returns true if the bounding box intersects any of the active voxels in a tree, i.e. ignores active tile values. | |
| template<typename TreeT > | |
| bool | anyActiveTiles (const TreeT &tree, const CoordBBox &bbox) |
| Returns true if the bounding box intersects any of the active tiles in a tree, i.e. ignores active leaf values. | |
| template<typename TreeT > | |
| bool | noActiveValues (const TreeT &tree, const CoordBBox &bbox) |
| Returns true if the bounding box intersects none of the active values in a tree, i.e. neither active voxels or active tiles. | |
| template<typename TreeT > | |
| Index64 | countActiveValues (const TreeT &tree, const CoordBBox &bbox) |
| Returns the number of active values that intersects a bounding box intersects, i.e. the count includes both active voxels and virtual voxels in active tiles. | |
| template<typename TreeT > | |
| std::vector< TileData< typename TreeT::ValueType > > | activeTiles (const TreeT &tree, const CoordBBox &bbox) |
| Return a vector with bounding boxes that represents all the intersections between active tiles in the tree and the specified bounding box. | |
Finds the active values and tiles in a tree that intersects a bounding box. Methods are provided that count the number of active values and tiles, test for the existence of active values and tiles, and return a list of the active tiles that intersect a bbox.
