How Do I Use My TruView Virtual Tour?
A TruView Virtual Tour is an immersive site visualization and collaboration tool that eliminates the need for complex CAD or BIM modeling software.
How is a TruView Generated?
During the 3D laser scanning process, in addition to capturing millions of 3D data points (the point cloud), the laser scanner also captures a 3D panoramic image (or TruView) at each scan position. A TruView is a high-resolution panoramic image that can be overlayed on top of the point cloud, making it easier to understand the spatial relationships within the scanned area.
GPRS Insight: The TruView is a "virtual street view" from each position where the laser scanner was set up during the 3D scanning process. A TruView allows our clients to navigate through the point cloud data as if they were standing at that specific scanner location, providing a visual context to the point cloud.
How Does GPRS Create a TruView?
The GPRS Mapping & Modeling Team imports the raw point cloud data into Leica Cyclone REGISTER 360 for alignment, cleaning, and processing. During registration, the TruView HDR image is mapped onto the point cloud for photorealistic visualization and is georeferenced for precise location accuracy. Then, the registered scan data is converted into a Leica TruView LGS or TVG format to open in the TruView Viewer software.
What is TruView Virtual Tour Software?
TruView is a free software from Leica Geosystems that allows users to share reality capture data from 3D laser scanners, such as point clouds, design models, mark-ups, and more.
TruView is available as both an online web viewer and an installed desktop application.
GPRS Insight: A TruView is a user-friendly platform to explore and collaborate on 3D project data, without needing advanced CAD skills or complex 3D modeling software.
What Can Users Do Inside Leica TruView Viewer?
The TruView Viewer is a software from Leica that allows users to open, view, measure, and annotate reality capture data, such as laser scan point clouds, AutoCAD files, and DWG files, from any computer or web browser without needing specialized software. The file sets must be made by Leica Cyclone TruView Publisher.
Leica TruView allows you to explore and interact with your 3D laser scan data in a virtual environment.
GPRS Insight: Users can navigate through the point cloud by "walking" through the different TruViews, essentially moving from one scanner position to another.
What are the Functionalities of the Leica TruView Viewer?
- View Project: The TruView Viewer allows users to access and navigate through 3D point cloud and HDR imagery captured by the laser scanner. Users can move through the scanned environment using pan, zoom, and rotate controls to inspect specific areas.
- Measurement Tools: Users can extract 3D coordinates to take accurate measurements of distances, angles, and dimensions directly within the virtual model.
- Markup Annotations: To aid collaboration, users can add annotations, comments, markups, and hyperlinks directly on the point cloud, making it easy to share insights.
- GeoTag Integration: Within a point cloud, specific locations can be linked to geographical coordinates, like latitude and longitude, through "GeoTags", allowing additional information about that location to be attached to each point, essentially creating a detailed map of the scanned area with extra details beyond just the 3D structure itself.
- Overlay CAD/BIM Data: CAD and BIM models can be integrated into to the TruView to compare existing conditions with design plans for validation. With the smart model align tool, users can easily align BIM models to the point cloud.
- Floor Flatness Analysis: Users can apply elevation color mapping or contour analysis and use measurement tools to assess deviations in surface levels.
- Pipe Snapping: Users can apply pipe snapping measurement tools in the distance measurement menu, including snap to pipe edge and snap to centerline.
- Pipe Diameter Measuring Tool: TruView offers a pipe diameter measurement when a pipe is selected.
- Virtual Reality (VR) Experience: TruView allows users to explore the point cloud in an VR environment using Mixed Reality headsets, reducing the need for a site visit. Users can enter a fully immersive VR experience directly from the desktop application. The tool provides true-to-life scale visualization, integrating colorized point clouds and models to inspect designs, test-fit equipment, or access hard-to-reach areas. Users can walk, fly, or teleport through projects, perform measurements, and collaborate in real time.
- GeoTag Settings: Users can color GeoTags by category for easier visual identification. Users can either batch change all GeoTags to one color or color them by category based on their assigned properties. The GeoTag occlusion slider controls how a Geotag is drawn when that GeoTag is partially hidden behind something else. Users also have the option to snap to GeoTags when measuring.
- Verification Reports: The verification report is used to track changes that have been made to the project, such as modifications to the registration or the addition of project assets or GeoTags.
- Export and Share: Share your project with stakeholders via web links, GeoTags, snapshots, or downloadable files for remote access and collaboration.
Do TruViews Have Any Limitations?
TruViews have limited functionality, users looking to alter designs should consider using AutoCAD software. AutoCAD is a more advanced, technically accurate software application that aids construction professionals, designers, engineers, and architects in conceptualizing designs and drawings. With AutoCAD, users can create floor plans, sections, walls, windows, doors, and other layouts. AutoCAD is not as easy to use as the TruView Viewer and there are subscription costs.
