Digital Review: an easy way to review virtual prototypes


TechViz’s Digital Review aims to improve the interaction in the Virtual Environment. It enables a thorough and dynamic 3D visualization so as to make the VR sessions useful and fruitful for the progress of your project.

An easy way to review Virtual Prototypes

The Digital Review functionalities offer an efficient and easy way to review the virtual prototypes with a dedicated set of tools. These functionalities aim to improve the interaction in the VR environment and the work done around the virtual prototype. Thanks to their user friendly interface, they are very easy to use.

Measure the distance between any two points. Hide and show parts to have a better understanding of the model. Stick virtual flags on the model with annotations to point out specific issues seen during the review. Clip planes to check different layers and navigate intuitively with Building Explorer.

How does the Digital Review option work ?

  • The Digital Review option operates with TechViz XL, the software with which to display your large 3D data sets or 3D virtual prototype directly from your native application.
  • TechViz XL and 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, no conversion is needed

Key features:

  • Natural metaphor of interaction
  • Easy to use
  • Dynamic interaction
  • Wide range of possibilities

Why use Digital Review?

  • Save viewpoints (bookmarks): stores the current user position towards the 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.
  • Measurements: measure the distance between two points, two surfaces (to get one angle) or 3 points to acquire the diameter of a circle.
  • 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 coworkers/ customers.
  • Hide/show specific parts of the model: 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.
