9.1 Understanding the LCC Studio Pipeline

What LCC Studio Does

LCC Studio (Lixel CyberColor Studio) is the 3D Gaussian Splatting processing software for the XGRIDS ecosystem. It accepts raw scan data from the K1, L2 Pro, and PortalCam and produces photorealistic 3D models in a proprietary format optimized for visual fidelity, compact file size, and web sharing.

The output is not a point cloud. It is a Gaussian Splatting model, a scene represented as millions of oriented, colored ellipsoids that collectively produce a photorealistic appearance under lighting. Gaussian models excel at visual quality and efficient rendering for visualization, virtual tours, and web sharing. They are not the correct format for dimensional measurement, BIM modeling, or GIS workflows. Those use cases require LixelStudio and point cloud output.

Pipeline Stages

Stage 1: SLAM Optimization

Like LixelStudio, LCC Studio begins by reconstructing the device trajectory from raw LiDAR and IMU data. The SLAM result determines the geometric accuracy of the model. The same SLAM mode options apply: Robust Mode is the default and handles most environments, None Mode maximizes accuracy in ideal conditions, and Narrow Scene Mode handles tunnels and long corridors. Narrow Scene Mode will fail in normal environments.

Stage 2: Gaussian Splatting Reconstruction

LCC Studio converts the SLAM-derived geometry and camera image data into a 3DGS model, a scene represented as millions of oriented ellipsoids, each with position, color, opacity, and covariance parameters. This stage is what makes LCC Studio output fundamentally different from point cloud output. The visual quality of the final model is determined by the reconstruction quality setting, the Max Gaussian Splats limit, and the quality of the camera data collected during the scan.

Stage 3: Camera Coloring Synchronization

Camera images recorded during the scan are synchronized with the SLAM trajectory and used to color the Gaussian splats. This is equivalent to the coloring stage in LixelStudio but operates on Gaussian geometry rather than point geometry. The PortalCam uses its built-in camera array for this step. K1 and L2 Pro can use built-in cameras or an external Insta360, which must be in normal video mode (not timelapse) for LCC Studio. Timelapse is required for LixelStudio. The mode requirement is the opposite between the two pipelines.

The LCC Format

LCC is a proprietary compressed format for Gaussian Splatting models. It is 20 to 40% of the size of an equivalent PLY file, making it the preferred format for delivery and archiving within the XGRIDS ecosystem. Models in LCC format can be viewed in LCC Studio, shared via LCC's one-click web publish, and opened in the LCC for BIM plugin in Revit.

PLY is the standard open format for 3DGS models and offers maximum compatibility with third-party tools. PLY files are 70 to 90% larger than equivalent LCC files for the same model. Use PLY when the recipient uses software outside the XGRIDS ecosystem.
