Specify the type of vector data (invariant, covariant, etc.) stored in this grid, assuming that this grid contains a vector-valued tree.

Set the values of all inactive voxels and tiles of a narrow-band level set from the signs of the active voxels, setting outside values to +background and inside values to -background.
Set the values of all inactive voxels and tiles of a narrow-band level set from the signs of the active voxels, setting outside values to outside and inside values to inside.
Also, set this grid's background value to outside.

Return the class of volumetric data specified by the given string.
If the string is not one of the ones returned by gridClassToString(), return GRID_UNKNOWN
.

inline |
Intersects this tree's set of active values with the active values of the other tree, whose ValueType
may be different.
The resulting state of a value is active only if the corresponding value was already active AND if it is active in the other tree. Also, a resulting value maps to a voxel if the corresponding value already mapped to an active voxel in either of the two grids and it maps to an active tile or voxel in the other grid.
|
inline |
Union this grid's set of active values with the active values of the other grid, whose value type may be different.
The resulting state of a value is active if the corresponding value was already active OR if it is active in the other grid. Also, a resulting value maps to a voxel if the corresponding value already mapped to a voxel OR if it is a voxel in the other grid. Thus, a resulting value can only map to a tile if the corresponding value already mapped to a tile AND if it is a tile value in other grid.
