関数

int BoxTest	(	v16	x,
		v16	y,
		v16	z,
		v16	width,
		v16	height,
		v16	depth
	)

Performs a test to determine if the provided box is in the view frustrum.

引数:

	x	(x, y, z) point of a vertex on the box
	y	(x, y, z) point of a vertex on the box
	z	(x, y, z) point of a vertex on the box
	height	(height, width, depth) describe the size of the box referenced from (x, y, z)
	width	(height, width, depth) describe the size of the box referenced from (x, y, z)
	depth	(height, width, depth) describe the size of the box referenced from (x, y, z)

戻り値:

non zero if any or all of the box is in the view frustum

void BoxTest_Asynch	(	v16	x,
		v16	y,
		v16	z,
		v16	width,
		v16	height,
		v16	depth
	)

Performs a test to determine if the provided box is in the view frustum.

引数:

	x	(x, y, z) point of a vertex on the box
	y	(x, y, z) point of a vertex on the box
	z	(x, y, z) point of a vertex on the box
	width	(width, height, depth) describe the size of the box referenced from (x, y, z)
	height	(width, height, depth) describe the size of the box referenced from (x, y, z)
	depth	(width, height, depth) describe the size of the box referenced from (x, y, z)

Performs a test to determine if the provided box is in the view frustum. BoxTestResult must be called to get the result of this operation.

int BoxTestf	(	float	x,
		float	y,
		float	z,
		float	width,
		float	height,
		float	depth
	)

Performs a test to determine if the provided box is in the view frustum.

引数:

	x	(x, y, z) point of a vertex on the box
	y	(x, y, z) point of a vertex on the box
	z	(x, y, z) point of a vertex on the box
	width	(width, height, depth) describe the size of the box referenced from (x, y, z)
	height	(width, height, depth) describe the size of the box referenced from (x, y, z)
	depth	(width, height, depth) describe the size of the box referenced from (x, y, z)

戻り値:

non zero if any or all of the box is in the view frustum

void BoxTestf_Asynch	(	float	x,
		float	y,
		float	z,
		float	width,
		float	height,
		float	depth
	)

Performs a test to determine if the provided box is in the view frustum.

引数:

	x	(x, y, z) point of a vertex on the box
	y	(x, y, z) point of a vertex on the box
	z	(x, y, z) point of a vertex on the box
	width	(width, height, depth) describe the size of the box referenced from (x, y, z)
	height	(width, height, depth) describe the size of the box referenced from (x, y, z)
	depth	(width, height, depth) describe the size of the box referenced from (x, y, z)

Performs a test to determine if the provided box is in the view frustum. BoxTestResult must be called to get the result of this operation.

void BoxTestResult

(

void

)

Gets the result of the last box test. Needed for asynch box test calls.

戻り値:

non zero if any or all of the box is in the view frustum
