[Gsoc-orga] GSoC 2025 Participant project idea

[Tobias Knerr]

Hello Jackson,

thanks for reaching out ahead of the application period. I'm one of the 
potential mentors for the 3D Model Repository project, the other being 
Sarah Hoffmann (in CC). Ideally, you can send future emails related to 
3DMR to the two of us.

I do appreciate your initiative in expanding the project idea. However, 
I would be reluctant to accept this either as a GSoC project or as a 
3DMR feature in general. We're focused on glTF support precisely because 
it's a "lowest common denominator" established, classical 3D graphics 
concepts. We want something widely supported by both model creation and 
display tools to make content from 3DMR super easy to adopt for OSM data 
consumers. Gaussian splatting as a technology doesn't have nearly that 
level of support throughout the 3D ecosystem yet, and afaik no 3D 
renderers for OSM data make use of it or any comparable approach.

Not sure where you want to go from here. If you're interested in 
applying for a 3DMR-related project anyway, we can discuss next steps we 
would expect before an application.

Yours,

Tobias
