Detailed Description

template<class GridType, typename RealType = double, bool bScalarCellSize = true>
class UE::Geometry::TTriLinearGridInterpolant< GridType, RealType, bScalarCellSize >

Tri-linear interpolant for a 3D dense Grid. Supports Grid translation via GridOrigin, but does not support scaling or rotation. If you need those, you can wrap this in something that does the xform.

GridType must have a GetValue() that returns a value to interpolate at a given FVector3i location – (w/ locations ranging from [0,0,0] to Dimensions (exclusive))
