Function Documentation

BoxTest()

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.

Parameters

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)

Returns

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

BoxTest_Asynch()

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

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

This is asynchronous. BoxTestResult must be called to get the result of this operation.

Parameters

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)

BoxTestf()

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

inlinestatic

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

Parameters

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)

Returns

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

BoxTestf_Asynch()

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

inlinestatic

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

This is asynchronous. BoxTestResult must be called to get the result of this operation.

Parameters

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)

BoxTestResult()

static int BoxTestResult ( void  )

inlinestatic

Gets the result of the last box test.

Needed for asynch box test calls.

Returns

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