@brief Removes all elements from the array and delete all pages. @warning Not thread-safe!

@brief Clears the y range for a given x value, setting it to an empty interval. @param x The x value.

@brief Return the cofactor matrix of this matrix.

Number of columns in the cube

@brief Access a const pointer to the first component being used as an abstract Expression @return A const pointer to the first component

@brief Computes the average cell points defined by the sign configuration @c signs and the given corner values @c values.

returns the world space voxel size for the given frustum depth.

@brief Computes the average cell point for a given edge group.

@brief Return the linear offset into this grid's value array given by the specified signed coordinates, i.e., coordinates in the space of this grid's

@brief Return a copy of this PageHandle

@brief Decode the value held by buffer[pid] based on the flag type. @details Certain types either cannot be encoded or can only be encoded with certa

@brief Query if this Crement node represents an decrement -- @return True if this node is performing an decrement

@brief Return the dimension, in index space, of this leaf node (typically 8 as for openvdb leaf nodes!)

@todo make pure

Dot product

@brief Return true if no trees being merged

@brief Returns true if the last substring of @b str equals the character sequence of @b pattern.

@brief Erode a single leaf node by the current spatial scheme stored on the instance of this NodeMaskOp. @details Unlike dilate, this method updates

@brief Sets the maximum y value for a given x value, if the provided ymax is larger than the current value. @param x The x value. @param ymax The maxi

@brief Sets the minimum y value for a given x value, if the provided ymin is smaller than the current value. @param x The x value. @param ymin The min

All calls to createLinearTransform with a matrix4 must to through this to avoid crashes when passing singular matrices into OpenVDB

This method is called by multiple places internally in Houdini.

Houdini assumes that the depth scaling of the frustum is being done in the linear part of the NonlinearFrustumMap. This method ensures that if the gri

@brief Return the half width of the narrow band in floating-point voxel units.

@brief Get the intersection point in index space. @param xyz The position in index space of the intersection.

@return the name, i.e. "base0123" if input is "path/base0123.ext"
