hello,I know the geometric error is measured in meters,and it means the error of the simplified geometry compared to the actual geometry.but I dont know how to compute it. for example, I have a osgb data and it's lod type is DISTANCE_FROM_EYE_POINT,when I convert the osgb to 3DTiles,how to compute the GEOMETRIC ERROR param? Is there some relation between DISTANCE_FROM_EYE_POINT and GEOMETRIC ERROR?
