vsgXchange now supports loading of 3DTile?

[tmonk22]

vsgXchange has added support for loading 3DTile. Does it support 3DTile extensions, such as vertex compression and texture compression? No support for related dependent libraries has been seen.

Which specific extensions? The new glTF loader supports Draco compression using the Draco library as a dependency. The vsgXchange::DDS and KTX loader supports GPU texture compression.

For example,
[3DTiles extension] 3DTILES_bounding_volume_S2 3DTILES_implicit_tiling
[gltf extension] EXT_meshopt_compression EXT_mesh_features

[robertosfield]

There isn't support for any of these extensions so far.

I've focused on 3D Tiles 1.0 & glTF 2.0 with the extensions required for the databases that my client funding the work requires. If members of the community require features beyond this then they'll need to help write them or help fund their development, or just be patient and hope that others will step in to help out.

I will make proper announcement of the work next week.

[tmonk22]

I am looking forward to it. If I have the ability, I hope I can provide some help in the future. At present, in the field of GIS visualization, (XYZ format) raster annotations and terrain can be loaded, including osgb data and 3dtile data. Will you consider adding vector data visualization in the future? For example, ground-based visualization of vector lines and vector polygons. Can you provide some ideas for this area?

[robertosfield]

I can't provide a roadmap for open ended topics.

What I will do, in th up comming threads about JSON, glTF and 3D Tiles is lay out what has been done and near term goals. Others may chip in to those threads.

It's worth realising that I already do a massive amount of work unpaid even without taking suggestions from community about what other work they'd like me to do for them for free. My client work is what all makes all the free support I provide possible, it's the client work that enables major new feature development like the above features.
