The C Tech Web Scene Viewer is 3D, interactive software for viewing and working with C Tech Web Scene (CTWS) files created by EVS. It allows users to manipulate the view and content of 3D models quickly in a straightforward manner.

• There are two versions of the Viewer:
  • Web Based: Our web based viewer can be accessed in several ways
    1. C Tech's Primary Viewer can always be found at https://viewer.ctech.com/ 
    2. Our EVS software customers may have their own branded viewer. Ask the organization (creator) who provides you with CTWS files.
    3. Our EVS software customers may also have the ability to embed C Tech Web Scenes directly into their website.
       • This eliminates your needing to receive the .CTWS files. Instead you only need the URL to a specific file such as: Tunnel Model
  • Standalone Viewer for Windows 10 & 11
    • Installer is available at https://client.ctech.com
    • Allows opening CTWS locally on the computer without internet access 
• Browser compatibility
  • The C Tech Web Scene Viewer works with most browsers to maximize its interoperability
  • However, we test the viewer with the most popular browsers and therefore we recommend the few below. Note, if your browser is not up to date, it may be a problem:
    1. Chrome
    2. Edge
    3. Safari (more limited testing)
• Devices
  • Windows Computers: The viewing of C Tech web scenes is most thoroughly tested on windows computers and therefore these will offer the greatest functionality. Certain features such as keyboard shortcuts may only be fully functional on Windows computers with a keyboard and numpad.
  • Mac Computers should work well, especially if Chrome is used since this is our primary browser for development and feature testing.
  • Tablets and Smartphones: Both Apple and Android phones are tested and new phones provide excellent performance. Keyboard shortcuts will be lacking, but most features are still accessible.
