Member Data Documentation

SplitPlaneType kdTreeAccel::BuildParams::kdSplitPlaneType

split plane generation method (defaults to SPLIT_PLANE_SAH)

Definition at line 68 of file kdTreeAccel.h.

SplitAxisType kdTreeAccel::BuildParams::kdSplitAxisType

split axis selection method (defaults to SPLIT_AXIS_ROUND_ROBIN)

Definition at line 71 of file kdTreeAccel.h.

unsigned kdTreeAccel::BuildParams::kdMinPrimitives

minimum number of primitives s.t. a leaf cell will automatically be created (below this number, further subdivision either won't help or requires too much memory)

Definition at line 76 of file kdTreeAccel.h.

unsigned kdTreeAccel::BuildParams::kdMaxDepth

maximum depth of tree

Definition at line 79 of file kdTreeAccel.h.

unsigned kdTreeAccel::BuildParams::kdNoThreads

number of threads to use during construction

Definition at line 82 of file kdTreeAccel.h.

bool kdTreeAccel::BuildParams::kdPostCompress

if true, after construction, will attempt to reorganize memory layout efficiently in memory

Definition at line 86 of file kdTreeAccel.h.

real_t kdTreeAccel::BuildParams::kdCostTraversal

SAH-specific parameters.

Definition at line 89 of file kdTreeAccel.h.

real_t kdTreeAccel::BuildParams::kdEmptyBias

Definition at line 90 of file kdTreeAccel.h.
