How does the Digital Review option work ?

  • The Digital Review option operates with TechViz XL, the 3D visualization softwarewith which to display your large 3D data sets or 3D virtual prototype directly from your native application (Dassault Systemes Catia V5Siemens NXPTC CreoNavisworks AutodeskRevit).
  • TechViz XL and all its options work on standard workstations under Windows 7, 8, 10 or Linux, 32 or 64 bits binary compatibility.
  • 3D applications are displayed on any VR devices and no conversion is needed

Why use Digital Review?

  • Measurements: measure the distance between two points, two surfaces (to get one angle) or 3 points to acquire the diameter of a circle.
  • Save viewpoints (bookmarks): stores the current user position towards the virtual model to load it in another session. The benefit is to jump directly to the 3D model’s places of interest without having to navigate from one place to the other.
  • Add section planes: clip the model along the direction the user selects. Magnetism effect is present in order to snap along the main axes of the model. Accurate values and position can be set in the GUI Otrack.
  • Take snapshots: save a picture of the current view in the master computer directory. Use them later in a report document or present one particular part to  your coworkers or customers.
  • Hide/show specific parts of the virtual prototype: as in CAD software, it is possible to hide selected parts, one after another, show them again or switch between hidden parts and shown parts.
  • Add annotation flags: a virtual flag is added in the VR environment pointing at the selected position, for future use. These comments can be saved and reloaded later for the project follow up, and can be deleted.
  • The Building Explorer functionality allows you to virtually visit the interior of a building. The user’s feet are like sucked to the ground in the virtual model. The user is able to climb stairs up and down.

A fluent virtual environment to save time efficiently

TechViz collaborative VR solution ensures real time data update and synchronizationfrom the different departments based in various locations. Navigation and interaction from every site is fluent: people can join or leave a session without affecting the connection of the other sites.

What are the benefits of this innovation in real time 3D? This evolution in the use of Virtual Reality Environments saves time through enhanced communication around a same 3D project : the visual medium is used to share ideas easily and efficiently.

TechViz TVZLib API
develop tailored interactive functionalities

Thanks to TechViz TVZLib API, developers can easily modify or create their existing desktop 3D application for a similar use within a VR environment. They can do so by programming their own functionalities, as well as easily integrating tracking information as inputs for real time 3D navigation and interaction, instead of only using a keyboard and a mouse. Furthermore all VR prerequisites are handled transparently by the TechViz XL core.

TechViz offers a programming library that can be adapted to a broad range of programming languages (C, C++, c#, python…). Integrating this C library within one OpenGL based developed application, users can either get back information from what is happening within the 3D environment or call TechViz functionalities. For instance: navigation functions when developing a new metaphor of navigation – virtual driver of navigation.
