Function Documentation

GLUSvoid GLUSAPIENTRY glusOrientedBoxCopyf	(	GLUSfloat	resultCenter[4],
		GLUSfloat	resultHalfExtend[3],
		GLUSfloat	resultOrientation[3],
		const GLUSfloat	center[4],
		const GLUSfloat	halfExtend[3],
		const GLUSfloat	orientation[3]
	)

Copies an oriented box.

Parameters

resultCenter	Destination center.
resultHalfExtend	Destination half extend.
resultOrientation	Destination orientation.
center	Source center.
halfExtend	Source half extend.
orientation	Source orientation.

GLUSfloat GLUSAPIENTRY glusOrientedBoxDistancePoint4f	(	const GLUSfloat	center[4],
		const GLUSfloat	halfExtend[3],
		const GLUSfloat	orientation[3],
		const GLUSfloat	point[4]
	)

Calculates the signed distance from an oriented box to a point.

If the value is negative, the point is inside the box.

Parameters

center	The center of the box.
halfExtend	The length from the center point to the planes of the box.
orientation	The orientation of the box.
point	The used point.

Returns

The signed distance.
