Functions

  Type Name Description
Public function void A height bounds for grids of cells of size "LowResInc" square, for faster culling.
Public function Const int32

CellIndexToVertexIndex ( const int32 CellIndex
)

 Convert a Cell Index to a Vertex Index. Returns the vertex index of the first corner in the cell. The other corners will be (VertexIndex + 1), (VertexIndex + NumCols), (VertexIndex + NumCols + 1). Most functions in this class take a vertex index.
