Detailed Description

An ADF Sample Address.

Generally this is only used for manipulation and maintenance of the address as an ADF is traversed.

Definition at line 47 of file adf.h.

void ADFSampleAddress::adjust_coordinate (  int  coord, int  delta, int  depth )

Definition at line 387 of file adf.cpp. References address. Referenced by adjust_for_child(), adjust_for_corner_sample(), and adjust_for_sample().

void ADFSampleAddress::adjust_for_child (  int  depth, int  child )

Samples in the center of one of the eight child cells. Definition at line 468 of file adf.cpp. References adjust_coordinate(), and octree_child_center_offset_ints. Referenced by ADF::init_traversal_node().

void ADFSampleAddress::adjust_for_corner_sample (  int  depth, int  corner )

Given the address for a cell, adjust the address so it points to the given sample of the cell. Depth is depth of current cell. Sample is a number from 0 to 8 (same labeling as children). Sampling occurs at (center of) vertices. Definition at line 453 of file adf.cpp. References adjust_coordinate(), and octree_child_center_offset_ints. Referenced by ADFTraversalNode::extract_samples_from(), and ADFPruner::is_used().

void ADFSampleAddress::adjust_for_sample (  int  depth, int  sample )

Given the address for a cell, adjust the address so it points to the given sample of the cell. Depth is depth of current cell. Sample is a number from 0 to 19 (same labeling as samples). Sampling occurs at center of each cell, faces, edges (total 19). Definition at line 435 of file adf.cpp. References ADF_sample_address_offset, and adjust_coordinate(). Referenced by ADFTraversalNode::is_reconstruction_valid().

double ADFSampleAddress::coord_to_point (  ADF *  adfp, int  coord )  const

Converts sample address to its spatial coordinats. Parameters: adfp  Pointer to an ADF object coord  Coordinate to be converted (0=x, 1=y, 2=z) Helper for to_point. Definition at line 485 of file adf.cpp. References address, Octree::center, Octree::length, and ADF::length_table. Referenced by to_point().

const ADFSampleAddress& ADFSampleAddress::operator= (  const ADFSampleAddress &  a  )  [inline]

Definition at line 60 of file adf.h. References address.

bool ADFSampleAddress::operator== (  const ADFSampleAddress &  a  )  const [inline]

Definition at line 68 of file adf.h. References address.

void ADFSampleAddress::set_to_root (   )

Root is at half the distance across the octree. So the root of the octree is at 0x4000. |--------| 0x8000 |----| 0x4000 |--| 0x2000 |-| 0x1000 ... Definition at line 418 of file adf.cpp. References address. Referenced by ADF::createADF(), and ADF::init_traversal_node().

void ADFSampleAddress::to_point (  ADF *  adfp, gmVector3 &  ret )  const

Converts address to coordinates. Definition at line 500 of file adf.cpp. References coord_to_point(). Referenced by ADF::get_sample().
