With polygon-based 3D formats, the higher the tessellation, the larger the file size. However, should better compression of the data be required, tessellation can be reduced but is balanced by a corresponding loss in fidelity and geometric accuracy. Regardless, compression of polygon-based data can typically be between 85-95% of the original CAD data file. XVL does not suffer from these issues, typically enabling 1/50 to 1/250 (i.e. better than 98%) compression of the data, in NURBs format, with high visual acuity and accuracy.
