Constructor & Destructor Documentation

Block() [1/2]

Block::Block	(	BlockGroup *	group,
		const std::vector< point_t > &	pts,
		const Bounds &	zrange
	)

Block Constructor. A model's body is a list of these blocks. The point data is copied, so pts can safely be freed after constructing the block.

Create a new block. A model's body is a list of these blocks. The point data is copied, so pts can safely be freed after calling this.
