10.10 LCC Studio Tools
A reference for every setting, mode, and tool in LCC Studio. Use this alongside Module 9 when processing 3D Gaussian Splat models from any Lixel device.
Reconstruction Settings
These settings appear when creating a new project in LCC Studio. They apply to all reconstruction modes: Single Scene, Map Fusion, Aerial-Ground Fusion, and Aerial Reconstruction. All settings must be configured before clicking Start Reconstruction. Projects queued for processing cannot be reconfigured without deleting and recreating them.
Do not close LCC Studio during reconstruction. Closing the application while a model is generating interrupts the process. When you reopen LCC Studio, interrupted projects display a failure status. Click Continue or Restart to re-queue. Closing the application does not save processing progress; the SLAM phase restarts from the beginning.
Disk space requirement: Reserve at least 2× the collected project data size as free disk space before starting reconstruction. Insufficient disk space causes reconstruction failure or interruption mid-run. Set the Project Path to an SSD outside the installation directory for maximum performance.
Reconstruction Modes
Single Scene
One uninterrupted scan session from a single device. The standard starting point for any project. Supports all devices: L2 Pro, K1, and PortalCam.
Map Fusion
Combines up to 10 scan segments from multiple sessions or battery changes into one unified model. Max 200 minutes combined scan duration. All segments must be from the same device type. PortalCam now supports Map Fusion in LCC Studio v1.10.0.
Aerial-Ground Fusion
Merges drone aerial imagery with ground scan data for complete exterior and interior coverage in a single model. Requires RTX 4090, 96 to 128 GB RAM, and a 16-core CPU. Processing time is typically 24 to 48 hours or longer.
Aerial Reconstruction
Processes ultra-large-scale scenes from drone-only imagery with no ground scan data required. Accepts 100 to 10,000 JPG/JPEG images at identical resolution of at least 1024 x 768 pixels. No Lixel device required.
Quality and VRAM Settings
Processing Quality
Maximum Gaussian Splats
This value sets a ceiling on the number of oriented ellipsoids (Gaussian points) the reconstructed model can contain. The correct value depends on which reconstruction mode is in use.
Portability
Portability simplifies the lighting model in the reconstruction to enable viewing on mobile devices and WebGL platforms. This setting is fixed at reconstruction time and cannot be changed after processing without reprocessing the entire scan.
PPR (Point Cloud Participation Rate)
PPR controls how heavily the LiDAR point cloud geometry influences the Gaussian Splatting model during reconstruction. Higher values pull the Gaussian ellipsoids closer to the actual LiDAR geometry, improving structural accuracy but increasing the risk of sky and edge bleeding in outdoor scenes where the LiDAR scan angle is limited.
Edge bleeding at outdoor boundaries is primarily caused by limited scanning angles rather than PPR setting alone. Capturing from multiple heights and angles during the scan prevents the issue at the source. Lowering PPR corrects the symptom in post-processing but does not recover geometry that was never captured.
Advanced Processing Options
These options appear in the debug and advanced settings panel when creating a project. Enable only when the specific condition described applies. Incorrect use increases processing time or reduces output quality.
Editor Tools
The Editor opens when clicking a Generated model in the project library. To view a model without entering edit mode, use the View function from the project settings menu (the "..." icon in the project card). All editing operations affect the saved LCC file. Use File > Save As before major editing operations to preserve a clean copy.
Interface Panels
Main Menu Bar
File, Edit, Settings, and Help menus. File contains Save, Save As, and import functions. Edit contains Undo and Redo (up to 50 operations). Undo history is cleared when you exit and re-enter the Editor.
Quick Access Toolbar
Open, Save, Undo, Redo, Move, Rotate, and Scale. The transform tools (Move, Rotate, Scale) apply to imported 3D assets, not to the scan model itself.
Tools Panel
Selection, Color Grading, Skybox, Measurement, and Notes tools. This is the primary editing panel for model cleanup and annotation.
View Controller
Switch between Flythrough, Pivot, and Avatar modes. Toggle rendering views and reset the origin point.
Assets Panel
Lists all visual assets in the current project: imported 3D models (.fbx, .glb, .obj) and placed notes. Supports individual asset management and visibility toggling.
Asset Overlay
Import external 3D assets (.fbx, .glb, .obj) to add context to the scene. Useful for overlaying design intent (a proposed addition in CAD format) against existing conditions (the scan). Use Move, Rotate, and Scale in the Quick Access Toolbar to position assets. Supports collision generation for immersive navigation through combined scenes.
Selection Tools
Selection tools define which portions of the Gaussian Splat model are targeted for deletion (cropping). Cropping is permanent on the active file. Always Save As before a major cropping operation. A conservative first pass followed by a refined second pass produces better results than attempting precision on the first selection.
Selection Methods
Selection Modifiers
Measurement and Annotations
LCC Studio measurement is not survey-grade. The measurement tool provides approximate distances and areas for reference use. Do not use these values for construction documents, permitting, or any application requiring certified dimensional accuracy. For measured deliverables, process the same raw data through LixelStudio to produce a point cloud, then measure from that output.
Measurement Types
Measurement Data Management
Measurements taken while editing (in the Editor) are saved automatically in real time to the LCC file. Measurements taken in the Viewer are temporary unless the viewer session was opened from a model that allows saving. Saved measurement data cannot be deleted from the Viewer; it can only be managed from the Editor. Switch between metric and imperial units in real time using the Measurement Unit Settings without affecting saved data.
Annotations (Notes)
Text notes with optional images and links can be placed at any point in the scene. Label conventions improve communication with collaborators: use prefixes such as "ISSUE:", "INFO:", and "SPEC:" to indicate the type and priority of each annotation when working on complex projects. Annotations saved in the Editor are preserved in web-published versions of the model, allowing clients to review issue notes without accessing the desktop application.
Color Grading
Color Grading adjusts the visual appearance of the Gaussian Splat model. Changes apply in real time, save automatically, and sync across the local Viewer and any published web viewer link. Color grading affects how the model looks, not the underlying geometry or data quality.
Consider maintaining two versions of high-value models: one graded for technical documentation (neutral, accurate) and one graded for marketing presentation (warmer, higher saturation). Color grading changes are reversible by resetting all sliders to zero, but maintaining separate files avoids the need to re-grade for each use.
Skybox
The Skybox tool replaces the background environment visible around the edges of the scan with a synthetic environment. Preset options represent different times of day and weather conditions. The skybox affects the perceived ambient lighting of the scene, so choose a preset that matches the lighting conditions during the scan for the most natural result. For interior-only scans where no sky is visible, skybox selection has minimal visual impact. Environment data (the raw scan environment) can be toggled independently of the skybox and is unaffected by model cropping.
Export Formats
LCC Studio exports 3D Gaussian Splat models in four primary formats plus an optional mesh output. The format choice is determined entirely by where the model will be viewed or used after export.
Publishing and Sharing
LCC Studio can publish models to the cloud for web-based viewing. Published models are accessible via a shareable URL on any modern desktop browser, tablet, or smartphone without requiring the viewer to install LCC Studio. This is the primary delivery method for client walkthroughs and stakeholder reviews.
Access Control Options
Managing Published Models
Published models can be unpublished at any time to revoke access without deleting the model. The Publish Management panel allows updating the model description, changing the access password, and toggling publish status. Model descriptions are visible to web viewers and provide context about the project, scan date, and scope. Write descriptions before publishing so clients receive context alongside the model link, not as a separate communication.
Color grading changes made in the Editor after publishing sync automatically to the published web viewer. Geometry changes (cropping) require republishing. Annotations added in the Editor after publishing also sync without requiring republication.
Spatial Flythroughs
The Spatial Flythrough tool captures a defined camera path through the scene and exports it as a video. Set keyframe viewpoints along a route through the model, define transition timing, and render. Use for presentations, reports, and client deliverables where a passive viewing experience is more appropriate than an interactive exploration. Requires the model to be open in the Editor.
Portal Projects
A Portal connects multiple separate LCC scenes into a single navigable experience. The user can jump between scenes via defined transition points, enabling multi-building campus tours, floor-to-floor navigation in multi-story projects, and connected indoor/outdoor experiences without loading multiple separate models.
