I would like to see Gaussian Spats in an X3D browser, as I'd like to use them in our interactive environments.<br>
<br>
Holger came up with a proposed Guassian Splat node for X3D/X_ITE, but it hasn't been implemented.<br>
<br>
My guess it would require some funding so that he could allocate resources, though I am not sure how the traditional polygon rendering pipeline fits with that needed to render splats.<br>
<br>
As far as how it fits with X3D, it's just content that I would like to include as part of an X3D scene.<br>
<br>
I would like to create web-based content for the University of North Dakota that includes gaussian splat models remote learning as part of our distance learning Geology courses.<br>
<br>
Effectively, we want to use the gaussian splat technique for rendering minerals/rocks that was demonstrated at the Web3D conference last year. This is a more realistic rendering of how light reflects and passes through 3D content generated from real-world minerals.<br>
<br>
I have a friend who works for a construction company doing construction site visualization, and they are eyeing gaussian splats for that instead of photogrammetry because they feel it looks better for the amount of effort needed to generate the content.<br>
<br>
There just needs to be an easy way to view it on the web. Sure you can use SuperSplats, but it would be nice if I could include gaussian splat content in my X3D environments.<br>

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