Detailed Description

Density is an 8 bit value where 0 means outside of the body and every value >0 lieas within the body. But a value of 1 actually means a density of zero too only that it will generate a body with zero volume. This way we can generate slopes down to a volume of zero or walls with a thickness of zero.
