Gaussian Splat basics

How to create and use a Gaussian Splat

The tools used in this tutorial

To generate a sparse point cloud from photo: COLMAP
to train the splats using the sparse cloud: Brush
and an open source editor to clean the ply: Superspl

Basic Step to create a 3DGS .ply file

The photos

Take multiple photos of the object or scene you want ( like when doing photogrammetry )

COLMAP

• Open COLMAP and press Automatic reconstruction

• Select the workspace folder and then the photo folder

• Uncheck Dense model
  

• Press Run and wait

• Once COLMAP has finished you will have the sparse cloud and the cameras visible like below
  

Brush

Open Brush and load the workspace folder of COLMAP

You can directly press start ( or play with the parameters if you know them )


Once the training is done you will find the ply inside the brush exe directory ( or you can export it using the control menu)

Superspl

You can open Superspl in your browser to clean and reorient the splat before importing it inside SMODE

Render the Gaussian Splat in SMODE

When the Gaussian Splat is imported inside SMODE you can use modifiers to mask, deform or change the color of your model
