Computes the LODs and bakes them into the mesh. <br>

This method must be fed with the reduction method
{@link TriangleReductionMethod} and a list of reduction values.<br> for
each value a LOD will be generated. <p> <strong>Important note: </strong>
some meshes cannot be decimated, so the result of this method can vary
depending on the given mesh. Also, the reduction values are approximate, and
the algorithm won't always achieve the specified reduction.

@param reductionMethod the reduction method to use
@param reductionValues the reduction value to use for each LOD level.
