	)

Adds the sphere to the scene and returns an object containing the sphere.

Parameters:

	sphere	The sphere to be added to the scene.
	scene	The scene where the created object is added.
	useAcc	States whether an acceleration structure (KDTree in our case) will be used to store the sphere.

Returns:: A pointer to the created object.

	deltaRadius	The value the radius should be changed with.
	rotAngle	The sphere will be rotated around the y-Axis with this angle.
	posOffset.	After having rotated the sphere this offset is added to the position of the sphere.

Extended rendering function that produces smoother edges. (Supersampling).

Parameters:

	scene	The scene object that will be rendered.
	prefix	The prefix is used for naming the result. (i.e. prefix == "test" => test1.png, test2.png, ...)

	sampleCount	The number of rays(samples) that will be shout for one pixel in the image.

Supersampling works as follows: For each pixel of the resulting image there will be shout more than one ray in a slightly different position (the SampleGenerator gives these positions) and these results will be interpolated.
