Subject: [x3d-public] splats on list or list on splats<br>
<br>
Hi,<br>
MSF 3D Assets had a meeting and asked me about Web3D and GSplats.<br>
I sort of said waiting for guidance from glTF and not much activity.<br>
(I had not really been thinking about it.)<br>
Then I thought to send the following to the MSF 3D Assets list.<br>
I would like to see demos to show at MSF meeting.<br>
<br>
Hi All, (MSF 3D Assets WG)<br>
I under reported Web3D interest and activity concerning nDGS, tiles, creation, transport, rendering, and interaction. Just wasn't following the topic.<br>
<br>
Now 'splats' activity on x3d-public(mailto:<a href="mailto:x3d-public@web3d.org" target="_blank">x3d-public@web3d.org</a>).<br>
<br>
"... it might help to have a couple of slides that show web3D interest."<br>
<br>
"It makes sense perhaps to do an X3D GaussianSplat Component and nodes matching like we did gltf/pbr.<br>
Then they would work like they do in 3D Tiles Sandcastle | CesiumJS "<br>
<br>
<a href="https://www.khronos.org/news/press/gltf-gaussian-splatting-press-release" rel="noreferrer" target="_blank">https://www.khronos.org/news/press/gltf-gaussian-splatting-press-release</a><br>
<a href="https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Khronos/KHR_gaussian_splatting/README.md" rel="noreferrer" target="_blank">https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Khronos/KHR_gaussian_splatting/README.md</a><br>
<br>
"why not just follow the new Khronos standard extension to gltf ?"<br>
<br>
"A Splatogrammetry solver component built into an x3d browser<br>
could simulate splat workflow ..."<br>
<br>
"... I think the glTF is not complete and maybe some proprietary stuffs ..."<br>
<br>
"add splat rendering node, at least gltf variant...<br>
all-in - add splat and photogrammetry component,<br>
with splats from MovieTexture or ImageTextures,<br>
including save to file ..."<br>
<br>
"I am using the term “data sources” rather than<br>
model or scene, because I don’t think those terms<br>
of scene or model apply to splat rendering."<br>
<br>
"... we want to use the gaussian splat technique for<br>
rendering minerals/rocks that was demonstrated<br>
at the Web3D conference last year."<br>
<br>
"... I had to look up splatting.<br>
Interesting and with high quality rendering<br>
Compared to X3D;<br>
1. Lose interactivity<br>
2. Lose real time data input to model.<br>
3. Lose extensibility<br>
It seems to be a runtime for image sourced 3D models."<br>
<br>
"How does this fit with X3D?"<br>
<br>
Add an experience session showing a couple of splatters and some gsplat tests?<br>
Thanks and All Best,<br>
Joe<br>
