	)			[inline]

Definition at line 25 of file triclip.cc.

int triBoxClip	(	const double	b_min[3],
		const double	b_max[3],
		const double	triverts[3][3],
		bound_t &	box,
		void *	n_dat
	)

function to clip a triangle against an axis aligned bounding box and return new bound

Parameters:

box

the AABB of the clipped triangle

Returns:

0: triangle was clipped successfully 1: triangle didn't overlap the bound at all => disappeared 2: fatal error occured (didn't ever happen to me :) 3: resulting polygon degenerated to less than 3 edges (never happened either)
