I’m trying to use Cesium to load a 3dTiles model with outlines, and the geometry of this model is compressed by draco.
I stored the compressed geometry as a bufferView, and the outlines data as a separate bufferView (outline indices are not compressed). The primitives extension part in the mesh includes both two fields: KHR_draco_mesh_compression and CESIUM_primitive_outline, like this:
The model generated by the above method does not load properly in Cesium.
Here is the 3dTiles model generate by my method.
3dTiles_draco_outlines.zip (3.3 KB)
The Cesium version is 1.96
What I want to know is
- how to properly generate the draco-compressed model with outlines?
- are there options or settings in CesiumJS I can use to properly control it?
