3DGS

Overview

The right‑click menu for model data in the Layer Management Tree provides operations for 3DGS data, including importing and removing 3DGS datasets, as well as per‑dataset actions such as viewing information, display settings, zoom‑to‑layer, and export.

Gaussian models demand significant GPU and memory resources. Before loading large models, ensure that your system has sufficient available resources.

Import Data

LiDAR360 supports the following Gaussian data formats:

• LiSplat (.LiSplat)
• PLY (.ply)
• Gaussian dataset (.xml)

Remove All

Removes all loaded model data from the software.

Context Menu for an Individual Loaded 3DGS Dataset

Information

Displays basic information about the dataset, including file path, and minimum/maximum X, Y, Z coordinates. Supported formats: LiSplat, PLY, and XML.

Open Containing Folder

Opens the folder where the current data file is stored.

Rename

Renames the current data file.

Zoom to Layer

Calculates the bounding box of the current 3DGS dataset and zooms the viewer window to fit the bounding box extent.

Display Settings (Render Settings)

Adjusts the rendering appearance of the Gaussian model. The following parameters are available:

• Brightness

  • Positive values: brighten the model
  • Negative values: darken the model
  • Default: 0

• Contrast

  • Positive values: increase contrast
  • Negative values: decrease contrast
  • Default: 0

• Opacity

  • Positive values: increase opacity
  • Negative values: decrease opacity
  • Default: 0

Click Default to reset brightness, contrast, and opacity to their default values.

• Render Level – Affects display quality only; does not modify the original Gaussian data. This setting is effective only for XML‑format Gaussian datasets.

• Save Rendering Adjustments – After adjusting brightness, contrast, and opacity, click Export in the Display Settings panel to save the adjusted result as a new Gaussian file:
  • The new file is saved in the same directory as the original, with an automatically generated filename.
  • The original file is never overwritten or modified.
  • This function mainly supports individual LiSplat files; XML‑based Gaussian datasets are not currently supported.

Export

Right‑click a Gaussian layer in the file tree and select Export to export the current Gaussian model to:

• PLY (.ply)
• LiData (.LiData)

Export creates new data files and does not modify the original Gaussian file.

Note the difference between the two export options:

Remove

Removes the currently selected 3DGS dataset from the software.
