virtual bool Opcode::BaseModel::Build ( const OPCODECREATE & create)

pure virtual

Builds a collision model.

Parameters

create [in] model creation structure

Returns: true if success

bool BaseModel::CreateTree	(	bool	no_leaf,
		bool	quantized
	)

protected

Creates an optimized tree according to user-settings, and setups mModelCode.

Parameters

no_leaf	[in] true for "no leaf" tree
quantized	[in] true for quantized tree

Returns: true if success
