Detailed Description

template<typename RealType>
class UE::Geometry::TVolPresQuadricError< RealType >

Quadric Error type for use in memory-less simplification with volume preservation constraints.

See: http://hhoppe.com/newqem.pdf or https://www.cc.gatech.edu/~turk/my_papers/memless_vis98.pdf for information about the volume preservation.
