Experience in developing VR simulators in 2021 based on HTC Vive. Part 2

Once again, I welcome Habr readers. I continue to share my experience in the process of creating VR simulators developed by our team this year.

The first part

A few days ago, our team returned from Vladivostok. Successfully delivered to the customer and passed all tests virtual welding simulator.

Unity was chosen as the base. As a VR – HTC Vive Cosmos Elite + 3 Trackers.

The tracker pins on the semi-automatic holder are connected to the start button.

Tasks set:

  • study of the functionality and basic principles of operation on a welding machine
  • training in practical rules of using welding equipment
  • reproduces the process: manual arc welding
  • Reproduces the process of: semi-automatic welding
  • automatically generates statistical data on the result of performing exercises

  • fasteners for electrode holder and burner
  • mask mount
  • rod for fixing the workpiece, height adjustable
  • workpieces for welding
  • rack
  • electrode holder and burner
  • mask with built-in 3D glasses

Required features:

  • visualization of welding machine operation
  • realistic simulation of welding sound in the virtual world
  • simulation of welding machine operation
  • coordination of the virtual scene in real time with the effects of the trainee on the controls
  • display on the monitor screen of the current parameters of the simulated welding process
  • statistical processing of results
  • studying a virtual welding seam after completing the exercise from different angles and different distances
  • the ability to choose exercises from a set
  • the ability to choose a workpiece for welding
  • display of the welding process in three-dimensional space using: virtual reality glasses, computer monitor
  • change the current strength for manual welding
  • change the wire feed speed for semi-automatic welding
  • get basic motor skills of ignition and maintenance of the welding arc
  • location simulating a welding room
  • simulation mode of the flow rate and electrode change in manual arc welding mode
  • formation of statistics on the results of exercises
