Syntax

FBox SplitTriangleList
(
    int32 Start,
    int32 NumTris,
    TArray< FkDOPBuildCollisionTriangle< KDOP_IDX_TYPE > > & BuildTriangles,
    TChunkedArray< FTriangleSOA > & SOATriangles,
    TChunkedArray< NodeType > & Nodes
)

Remarks

Determines if the node is a leaf or not. If it is not a leaf, it subdivides the list of triangles again adding two child nodes and splitting them on the mean (splatter method). Otherwise it sets up the triangle information.

Returns

bounding box for this node

Parameters

Parameter	Description
Start	The triangle index to start processing with
NumTris	The number of triangles to process
BuildTriangles	The list of triangles to use for the build process
Nodes	The list of nodes in this tree
