creation is easier, but with this method there occur ugly

looking artifacts when the camera is inside the shadow volume.

well in OpenGL and fails with other drivers).

zfail method, if not, zpass is used.

\param infinity: Value used by the shadow volume algorithm to

scale the shadow volume. For zfail shadow volumes on some drivers
|
|
only suppport finite shadows, so camera zfar must be larger than
|
|
shadow back cap,which is depending on the infinity parameter).
|
|
Infinity value also scales by the scaling factors of the model.

If shadows don't show up with zfail then try reducing infinity.

If shadows are cut-off then try increasing infinity.
