Function Documentation

RtWorldImportGuideKDTree* RtWorldImportGuideKDAddPartition (  RtWorldImportGuideKDTree *    KD,
RwInt32    type,
RwReal    value
) 
 

RtWorldImportGuideKDAddPartition Modifies a given leaf node, by partitioning it, turning the given node into a non-leaf node, and creating two new leaf-node children

Parameters:
KD  The leaf node of the RtWorldImportGuideKDTree
type  The orientation of the partition 0, 4, 8 for normal to the x, y or z-axis
value  The signed distance of the plane from the origin
Returns:
The new node if successful, NULL otherwise. A partition is invalid if it is not inside the half space of its parent

RtWorldImportGuideKDTree* RtWorldImportGuideKDCreate (  RwBBox *    bbox ) 
 

RtWorldImportGuideKDCreate Creates a single node RtWorldImportGuideKDTree

Parameters:
bbox  The bounding box of the world.
Returns:
The root of the RtWorldImportGuideKDTree

void RtWorldImportGuideKDDeletePartition (  RtWorldImportGuideKDTree *    KD ) 
 

RtWorldImportGuideKDDeletePartition Modifies a given node, by destroying its childern, turning the given node into a leaf node.

Parameters:
KD  The node of the RtWorldImportGuideKDTree

RtWorldImportGuideKDTree* RtWorldImportGuideKDRead (  const RwChar *    filename,
const RwBBox *    bbox
) 
 

RtWorldImportGuideKDRead Reads in a previously saved KD tree and stores it in a RtWorldImportGuideKDTree. This can subsequently be applied to a world using a guided build.

Parameters:
filename  A pointer to the filename where the KD tree is stored
bbox  The bounding box of the world
Returns:
A pointer to the RtWorldImportGuideKDTree

RtWorldImportGuideKDTree* RtWorldImportGuideKDWrite (  RtWorldImportGuideKDTree *    guideKD,
const RwChar *    filename
) 
 

RtWorldImportGuideKDWrite Saves the given RtWorldImportGuideKDTree

Parameters:
guideKD  A pointer to the RtWorldImportGuideKDTree.
filename  A pointer to the filename where it is to be stored.
Returns:
The RtWorldImportGuideKDTree.
