virtual reality (vr)
Virtual reality (VR) simulates an environment in three dimensions to visualize objects and / or have certain tasks performed by the environment or its user.
CTA specializes in 2 types of virtual reality projects, namely:
- Product visualization and technical staff training projects. The result allows a better understanding of systems and product functions.
- Immersive driving simulation. These projects combine VR with articulated physical simulators on which users are seated or standing. They thus receive a multitude of sensory stimuli which allow an almost total simulation.
- Complete interactive virtual reconstruction of the Rotax 903 turbo engine from BRP for training purposes.
- Assembly experience of a Rotax engine in the form of a timed competition.
- Complete interactive virtual reconstruction for the launch of BRP’s Can-Am Ryker with interactive and voice activated exploded views.
