[x3d-public] splats on list or list on splats

[Joe D Williams]

I attached two MSF slides first asking where does MSF fit in as a facilitator toward engagement and actual specs?
Second some planning for a "Town Hall" show about various compression details.
Should web3D be in there?
Any ideas how to advance splats into glTF and X3D standards?
Prospective Nodes and fields?
Thanks,
Joe

Hi,
MSF 3D Assets had a meeting and asked me about Web3D and GSplats.
I sort of said waiting for guidance from glTF and not much activity.
(I had not really been thinking about it.)
Then I thought to send the following to the MSF 3D Assets list.
I would like to see demos to show at MSF meeting.

Hi All, (MSF 3D Assets WG)
I under reported Web3D interest and activity concerning nDGS, tiles, creation, transport, rendering, and interaction. Just wasn't following the topic.

Now 'splats' activity on x3d-public(mailto:x3d-public at web3d.org).

"... it might help to have a couple of slides that show web3D interest."

"It makes sense perhaps to do an X3D GaussianSplat Component and nodes matching like we did gltf/pbr.
Then they would work like they do in 3D Tiles Sandcastle | CesiumJS "

https://www.khronos.org/news/press/gltf-gaussian-splatting-press-release
https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Khronos/KHR_gaussian_splatting/README.md

"why not just follow the new Khronos standard extension to gltf ?"

"A Splatogrammetry solver component built into an x3d browser
could simulate splat workflow ..."

"... I think the glTF is not complete and maybe some proprietary stuffs ..."

"add splat rendering node, at least gltf variant...
all-in - add splat and photogrammetry component,
with splats from MovieTexture or ImageTextures,
including save to file ..."

"I am using the term “data sources” rather than
model or scene, because I don’t think those terms
of scene or model apply to splat rendering."

"... we want to use the gaussian splat technique for
rendering minerals/rocks that was demonstrated
at the Web3D conference last year."

"... I had to look up splatting.
Interesting and with high quality rendering
Compared to X3D;
1. Lose interactivity
2. Lose real time data input to model.
3. Lose extensibility
It seems to be a runtime for image sourced 3D models."

"How does this fit with X3D?"

Add an experience session showing a couple of splatters and some gsplat tests?
Thanks and All Best,
Joe
