Single Scene Processing

Importing Your Data

Transfer Methods

LCC Studio supports three data import paths: manual file selection from local storage, USB drive mode for direct reads from connected external storage, and automatic device file reading for connected XGRIDS devices.

• L2 Pro and K2: Connect via USB and transfer the raw scan folder from internal storage to the workstation SSD. Both devices have non-swappable internal storage. K2 supports the new automatic device file reading workflow.
• K1 (legacy): Remove the TF card and transfer scan data to the workstation SSD via card reader. K1 storage is field-swappable.
• PortalCam: Transfer via the LCC Scan app export function or USB connection. PortalCam internal eMMC is not field-swappable.
• USB drive mode: LCC Studio can read raw capture files directly from connected USB drives, SSDs, and external storage. Network storage (OneDrive, NAS) is not supported.

Storage and Path Requirements

• Reserve at least 2 times the project data size as free disk space. LCC Studio writes substantial intermediate data during reconstruction. Insufficient disk space causes reconstruction failure or interruption mid-run.
• Set the Project Path to a dedicated SSD outside the installation directory. Settings > General > Project Path > Select Directory. SSD storage significantly improves generation and processing speed.
• Set the Capture Data Backup Path via Settings > General > Capture Data Backup Path. An SSD is recommended for backup as well.
• Keep the original data on the device until processing is verified. Do not delete device files after copying. The cost of storage is not comparable to the cost of a return site visit.

Automatic Device File Reading (New)

LCC Studio introduces automatic device file reading. When you connect an XGRIDS scanner device via USB, LCC automatically detects the external device and reads project information, simplifying data import.

1. Connect the XGRIDS device to the computer via USB.
2. Open the device dialog. When the system detects the device, a notification appears in the lower-right corner of the screen. Click it.
3. Review the device dialog. The dialog shows device model and serial number, importable project list (name, file size, capture date). Previously imported projects are grayed out.
4. Select the reconstruction method. If the connected device is a scanner, only single-scene quick import and reconstruction is currently supported via this workflow.
5. Set the file storage path. Defaults to the configured capture data backup path.
6. Click Start Reconstruction. The project is added directly to the reconstruction queue.

Pre-Reconstruction Point Cloud Preview

After uploading capture data and before starting reconstruction, use the Point Cloud Preview tool to check scan trajectory and point cloud quality. This catches collection problems before committing hours of GPU time to reconstruction.

1. Upload capture data via Create > Single Model.
2. Click Point Cloud Preview. The system runs quality checks on the capture data.
3. Review the quality indicator results. Adjust capture data before reconstruction to improve success rate and final quality.
4. Click View Point Cloud to enter the Point Cloud Preview tool. View the capture trajectory and coarse point cloud. Controls match LCC Editor.

Creating a Single Model Project

1. Open LCC Studio and click Create. Select Single Model from the reconstruction type options.
2. Name the project using a clear, consistent convention. The name is used in exported filenames and in the web publish link.
3. Add the scan data folder under Ground Data. LCC Studio reads the device type from the folder contents and displays it in the interface.
4. Set Quality. Standard is the correct starting point for all first-attempt processing. Use Fast only for previews. Use Slow for final deliverables requiring maximum visual fidelity.
5. Set Max Gaussian Splats. The Estimated VRAM bar shows projected GPU memory usage as you adjust. Stay within the bar for your GPU. For consumer GPUs, stay under 25M in Single Model mode to avoid VRAM overflow, memory failure, or degraded reconstruction quality.
6. Set Portability. On for web or mobile delivery, reduces file size and improves cross-device performance. Off for desktop-only delivery requiring realistic lighting effects. USDZ export requires Portability Off.
7. Configure Advanced Settings if needed. Special SLAM Mode: Auto for most environments. PPR: Normal for indoor, Low for outdoor. RTK Data: Auto (default) or Disabled if RTK is causing instability. Exposure Optimization: enable only if floating artifacts appear in scenes with dramatic lighting changes.
8. Enable Low-Memory Mode only if the project fails due to RAM limitations. This option offloads intermediate data to disk, reducing peak RAM usage at the cost of increased processing time. It is only available in Single Model mode.
9. Click Start. Close all other applications before starting, including browsers (Chrome with multiple tabs consumes significant GPU memory), other 3D applications, video editing software, and any tool that uses the GPU. LCC Studio reconstruction is GPU-intensive and competes directly for VRAM with any other running application. Do not close LCC Studio during processing.

Advanced Features Available in Single Model

Single Model reconstruction supports two advanced features beyond standard 3DGS output. Both are optional and add processing time, but unlock specialized deliverables.

Spatial Recognition

For indoor environments, enable Spatial Recognition. The system automatically identifies walls, doors, windows, and other architectural structures, organizing them into a structured intelligent floor plan. Useful for spatial analysis, renovation planning, and BIM modeling preparation in the LCC for BIM Revit plugin.

Hardware requirement: GPU VRAM > 8 GB. Insufficient VRAM prevents the feature from running.

K2 support: Spatial Recognition is available for K2 within Single Model reconstruction.

HD Enhancement

For key areas requiring higher detail and texture quality (landmarks, equipment labels, decorative elements), use HD Enhancement. Capture additional high-resolution photos with a DSLR or smartphone. These photos combine with original scan data to enhance detail and texture quality.

Hardware requirement: GPU VRAM > 8 GB.

Photo requirements: L series (L2 Pro, K1) supports 20 to 500 photos; PortalCam supports 20 to 1,000 photos. JPG, PNG, JPEG only. All supplementary photos must be taken with the same device.

Reviewing Results in the Viewer

After reconstruction, the model opens in the LCC Studio viewer. Use the viewer to verify visual quality, coverage completeness, and dimensional accuracy before exporting or publishing.

Navigation Modes

Flythrough mode uses WASD for movement and mouse for direction. Scroll wheel adjusts movement speed. Shift accelerates (sprint). Pivot mode rotates around a selected point with right-click panning and scroll zoom. Double-click sets a new pivot center. Avatar mode (View mode only) simulates ground-level walking with collision detection. Measurement and annotation tools are available in Flythrough and Pivot modes but not in Avatar mode.

Quality Verification Checklist

• Navigate the full extent of the model and confirm all required areas are present. Missing zones cannot be recovered in post-processing.
• Check coverage at transitions, including doorways, stairwells, and areas where scanning speed may have been higher.
• Verify a known dimension using the measurement tool. A room that measures significantly differently from known dimensions indicates SLAM drift. The entire scan may have an accuracy problem that requires rescanning.
• Inspect visual quality in areas that matter most to the deliverable. Equipment labels, MEP details, and fine architectural elements require adequate scan coverage from multiple angles to reconstruct cleanly.
• Check for reconstruction artifacts, including floating geometry, blurry surfaces, or areas with inconsistent density. These typically indicate zones where loop closure was insufficient or scanning speed was too high.
