int G3D::NativeTriTree::Settings::accurateSAHCountThreshold

SAH uses an approximation to the published heuristic to reduce splitting from $O(n^2)$ to $O(n)$ .

When the number of Tris to be divided at a node falls below accurateSAHCountThreshold, it switches to the full heuristic for increased accuracy.

Set to zero to always use the accurate method and std::numeric_limits<int>::max() to always use the fast method.

SplitAlgorithm G3D::NativeTriTree::Settings::algorithm

bool G3D::NativeTriTree::Settings::computePrevPosition

float G3D::NativeTriTree::Settings::maxAreaFraction

Fraction of the bounding box surface area that one polygon is allowed to contribute before it is forced to be stored at an internal node.

Set to inf() to disable placing triangles at internal nodes.

1/6 = a triangle cutting across an entire cube will be placed at that node, if it spans the splitting plane.

int G3D::NativeTriTree::Settings::valuesPerLeaf

Put approximately this many triangles at each leaf.

Some leaves may have more because no suitable splitting plane could be found.
