Detailed Description

Used for temporary storage of ADF nodes during traversal or construction.

Note that samples are not automatically extracted during traversal, for efficiency; extract_samples_from must be called before performing any real operations with the node. get_local_coord_distance assumes the point is in the local coordinate frame of the node.

void ADFTraversalNode::estimate_normal (  const gmVector3 &  p, gmVector3 *  normal )

Returns (in normal) the central-differenced gradient at world-coordinate point p. Definition at line 802 of file adf.cpp. References OctreeTraversalNode::center, collect_bilinear_weights(), OctreeTraversalNode::length, and samples. Referenced by ADF::get_distance().

void ADFTraversalNode::extract_samples_from (  ADF *  adfp  )

Grabs samples from ADF and stores locally. TraversalNode has its own sample array. Definition at line 719 of file adf.cpp. References address, ADFSampleAddress::adjust_for_corner_sample(), ADF::get_sample(), and samples. Referenced by ADF::createADF(), ADF::get_distance(), and ADFRefiner::should_split().

double ADFTraversalNode::get_distance (  const gmVector3 &  p  )

Returns the reconstructed distance at world-coordinate point p. Definition at line 763 of file adf.cpp. References OctreeTraversalNode::center, get_local_coord_distance(), and OctreeTraversalNode::length. Referenced by ADF::get_distance().

double ADFTraversalNode::get_local_coord_distance (  const gmVector3 &  pp  )

Returns the reconstructed distance at cell-coordinate point p. Definition at line 781 of file adf.cpp. References collect_trilinear_weights(), and samples. Referenced by get_distance(), and is_reconstruction_valid().

bool ADFTraversalNode::is_reconstruction_valid (  ADF *  adfp  )

Checks ADF node reconstruction against samples. Todo: this is place to change if we want to change the sampling testing with the new interval testing. Definition at line 736 of file adf.cpp. References address, ADF_sample_offset, ADFSampleAddress::adjust_for_sample(), ADF::epsilon, get_local_coord_distance(), and ADF::get_sample().
