		CC3AngularVector	subtrahend
	)

Note that this is NOT true vector arithmetic, which would yield a completely different angular and radial results.

CC3AngularVector CC3AngularVectorFromVector ( CC3Vector v )

Returns an CC3AngularVector providing the heading, inclination & radius of the specified CC3Vector.

Heading is measured in degrees, in the X-Z plane, clockwise from the negative Z-axis. Inclination is measured in degrees, with up being in the positive-Y direction.

		GLfloat	inclination,
		GLfloat	radius
	)

CC3Plane CC3PlaneFromPoints	(	CC3Vector	p1,
		CC3Vector	p2,
		CC3Vector	p3
	)

Returns a CC3Plane structure that contains the specified points.

The direction of the normal of the returned plane is dependent on the winding order of the three points. Winding is done in the order the points are specified (p1 -> p2 -> p3), and the normal will point in the direction that has the three points winding in a counter-clockwise direction, according to a right-handed coordinate system. If the direction of the normal is important, be sure to specify the three points in the appropriate order.

		CC3Plane	plane
	)

Returns the location of the point where the specified ray intersects the specified plane.

The returned result is a 4D vector, where the x, y & z components give the intersection location in 3D space, and the w component gives the distance from the startLocation of the ray to the intersection location, in multiples of the ray direction vector. If this value is negative, the intersection point is in the direction opposite to the direction of the ray.

If the ray is parallel to the plane, no intersection occurs, and the returned 4D vector will be zeroed (equal to kCC3Vector4Zero).

CC3Ray CC3RayMake	(	GLfloat	locX,

	)

CC3Vector CC3VectorFromTruncatedCC3Vector4 ( CC3Vector4 v )

CC3Vector CC3VectorInvert ( CC3Vector v )

CC3Vector CC3VectorMaximize	(	CC3Vector	v1,
		CC3Vector	v2
	)

		CC3Vector	v2
	)

Returns a vector whose components comprise the minimum value of each of the respective components of the two specfied vectors.

CC3Vector CC3VectorNegate ( CC3Vector v )

Returns a vector that is the negative of the specified vector in all directions.

For vectors that represent directions, the returned vector points in the direction opposite to the original.

CC3Vector CC3VectorNormalize ( CC3Vector v )

Returns a normalized copy of the specified CC3Vector so that its length is 1.0.

	)

Returns an ccColor4F structure whose values are a weighted average of the specified base color and the blend color.

The parameter blendWeight should be between zero and one. A value of zero will leave the base color unchanged. A value of one will result in the blend being the same as the blend color.

		GLfloat	green,
		GLfloat	blue,
		GLfloat	alpha
	)

Returns a ccColor4F structure constructed from the specified components.

ccColor4F CCC4FUniformScale	(	ccColor4F	rgba,
		GLfloat	scale
	)

Returns a ccColor4F structure whose values are those of the specified original color, multiplied by the specified scaling factor.

Each of the resulting color components is clamped to be between 0.0 and 1.0.

ccColor4F CCC4FUniformTranslate	(	ccColor4F	rgba,
		GLfloat	offset
	)

Returns a ccColor4F structure whose values are those of the specified original color, where each color component has been translated by the specified offset.

Each of the resulting color components is clamped to be between 0.0 and 1.0.

Returns a string description of the specified CC3Vector4 struct in the form "(x, y, z, w)".

NSString* NSStringFromCC3Viewport ( CC3Viewport vp )

Returns a string description of the specified CC3Viewport struct in the form "(x, y, w, h)".

NSString* NSStringFromCCC4F ( ccColor4F rgba )

Returns a string description of the specified ccColor4F in the form "(r, g, b, a)".

NSString* NSStringFromTouchType ( uint tType )

Returns the name of the specified touch type.

ccColor4F RandomCCC4FBetween	(	ccColor4F	min,
		ccColor4F	max
	)

Returns a random ccColor4F where each component value between the specified min inclusive and the specified max exclusive.

This can be useful when creating particle systems.
