Functions for iterating over the metadata

@brief Return the number of voxels that defined the boundary condition.

@brief Clears the data container

@brief Access a const pointer to the second component being used as an abstract Expression @note This can be a nullptr for single indexing operatio

@brief @tparam ValueT @param grid @param mode @return

@brief Create and initiate entire look-up-table for CRC32 computations @return returns a unique pointer to the lookup table of size 256.

@brief Return both the mean and the Gaussian curvature at the previously buffered location. @note This method should not be called until the stencil

@brief Return the dimension, in voxel units, of this internal node (typically 8*16 or 8*16*32)

Return @c true if this grid contains only inactive background voxels.

@brief Return @c true if this bounding box is empty (i.e., encloses no coordinates).

@brief Encode the value held by "in" based on the flag type, to the location pointed to by buffer[pid]. @details Certain types either cannot be encod

Iterator past the end of the image data

Returns vector of x,y,z rotational components

@brief Simple wrapper that calls cudaFree @param d_ptr Device pointer that will be freed @param dummy The stream establishing the stream ordering prom

Generate random points by uniformly distributing points on a unit-sphere.

@return coordinate bbox in the space of the specified transfrom

Global function for accessing the registry

@brief Return the current logging level.

Global function for accessing the regsitry

@brief Return an unsafe accessor that provides random read and write access to this grid's voxels. @details The accessor is unsafe in the sense that i

@brief Return the total number of grids contained in this buffer

@brief Query whether or not this has an optional if-true branch.

@brief Return @c true if this bounding box has (positive) volume.

@brief Access a const pointer to the initialiser @return A const pointer to the initialiser

@brief returns inverse of this

@brief Return the active state of the given voxel (regardless of state or location in the tree.)

@brief Query whether or not this is a compound AssignExpression. Compound AssignExpressions are assignments which read and write to the LHS value. i.

@brief Check whether this function should be only internally accesible

Return the (key, value) map as a Python dict.

@brief Query the keyword held on this node. @return The keyword as a tokens::KeywordToken

@brief Returns the number of resolution levels.

Return the mean curvature multiplied by the norm of the central-difference gradient. This method is very useful for mean-curvature flow of level sets!

@brief Compatbility wrapper for cudaMemAdvise/cudaMemAdvise

@brief Compatbility wrapper for cudaMemPrefetchAsync/cudaMemPrefetchAsync

@brief Return the midpoint of the ray.
