Free Software for Virtual Site Visits on a Windows PC

Leica TruView is the industry leader for easily and intuitively sharing point cloud data, and virtual walkthroughs for a Windows PC. Leica provides this software free of charge and offers two formats for the software: a portable option that can be placed on a USB drive which does not require installation, and a standard desktop installation that installs on a Windows PC. Both versions have specific video card and hardware requirements that must be met to function properly.

TruView utilizes the Leica LGS\LGSX file format which allows for a large amount of data in a smaller file size than offered in other file formats. It allows imagery, dimensional information, and point cloud data to be hosted in one file, making it easy to download and share.

Existing Conditions provides the LGS\LGSX file with every project that utilizes a Leica 3D laser scanner. These files are hosted for free in our Project Delivery folder and can be downloaded or shared easily with others. 

Alternatively, if you need to access the Virtual Walkthrough data from any web-enabled device, the Existing Conditions' Virtual Site Visits platform is an easy, secure, and low-cost way to access this same type of project data, regardless of your operating system or hardware. This platform can be accessed from any desktop, tablet, or mobile device – all you need is an internet connection.

How to install TruView

If the project folder contains a "TruView" folder, then continue reading for how to download and use the TruView software and files.

The TruView file format is LGS or LGSX. This data contains the 3D Panoramic view of the scan data for each scanner location. You will need to use either the TruViewPortable (no installation required) or the full TruView Install to view the LGS\LGSX files.

Option 1 - TruView Portable is a viewer that does not need to be installed and can be placed on a USB stick or drive and transferred with the LGS data.

Option 2 - TruView Install is a standard Windows software that can be installed and run to view the LGS data. (This is the recommended option). If you have a 3D VR headset, you can also download the TruView VR software from this location to utilize the VR interface.

How to make the most of TruView

  1. Download an LGS file containing the scan data that you want to view in TruView.
  2. Open TruView by either double-clicking on the TruView application or dragging and dropping the LGS file onto the TruView interface.

  4. To pan around the sitemap view, press and hold the right click on your mouse, then drag left to right. 
  5. Double-click on a red dot to enter the first-person (bubble) view of that scan location. This view provides a 360-degree perspective of the scanned area.
  6. Navigate between scan locations by double-clicking on other red dots on the sitemap view.
  7. In the first-person view, utilize tools such as the dimension tool to take measurements between points in the scan data.
