Supported features

The tile-converter is capable to convert 3D tiles data of formats 3DTiles and I3S. Both 3DTiles and I3S are wide specifications included many internal formats and data types. The tile-converter doesn't cover all features described in those specifications. This sheet summarise compatibility of the tile-converter with different parts and features of 3DTiles and I3S.
