(Large) Gaussian Splat from a Train Station

Hey, I’d like to share my first model featuring a larger Gaussian Splat:
Train Station
It’s a train station with 8 million splats, totaling 135 MB. The entire project size is 476 MB. I added a mesh collider from the scan, which was optimized and reduced in ZBrush. Additionally, I included an NPC. :wink:

My Chromebook got so slow lol.

Sorry for that. I reduced the splat, but unfortunately its still heavy.

Nah, man, I can’t even load the web based Minecraft on playcanvas.

This works pretty well! Nice job.

What was the process for generating the collision mesh from the photogrammetry/splat?

Thx, Will! Fortunately, the Xgrid scanner exports a mesh while creating the Splats. I used this mesh and modified it to fit my needs. It’s a pretty nice feature—otherwise, creating this complex collision model would be a real pain in the a** :joy:

Interesting! I would love to get my hands on one of those XGRIDS scanners - I think they’re quite expensive though.

Feedback on your demo:

  • The robot (and NPC) probably needs to be scaled down ever so slightly. They seem large compared to the size of the door at the front of the station building.
  • The lighting on the robot seems quite different to the lighting conditions of the environment. Getting them to match up a bit better would help make the robot sit in the environment better.

The K1 scanner costs round about 13k EUR, thats quite cheap in comparison to other devices and techniques.
Thanks for your hints, I´ll take a look onto it. I would also like to change the character to a more natural one, but I must first take a deeper look on the workflow to replace the character.

Hi,

I recently used the L2 Pro to scan and make something similar: Collision_Volume_for_3DGS_Scene - PLAYCANVAS

Do you know how to make the movement of camera / character in the scene faster? To me I hope the speed of movement can be at least 2x faster.
