Syntax

virtual void FastCollapsePass
(
    double MinEdgeLength,
    int Rounds,
    bool bMeshIsClosedHint
)

Remarks

Does N rounds of collapsing edges longer than fMinEdgeLength. Does not use Quadrics or priority queue. This is a quick way to get triangle count down on huge meshes (eg like marching cubes output).

Parameters

Parameter	Description
MinEdgeLength	collapse any edge longer than this
Rounds	number of collapse rounds
MeshIsClosedHint	if you know the mesh is closed, this pass this true to avoid some precomputes
