Free and open-source computer-aided design/Virtual environments for scenario modelling

This feature enables a virtual 'location' to be selected (or created) in order to show an item in context in its intended environment. Many people can gather in this virtual space to see demonstrations for example, or it can used as an easy tool to animate a concept for others to view later as a narrative.

This kind of scenario modelling might be similar to the way advanced 3D computer games are rendered - in realtime and with physics engines to simulate gravity, friction etc. A similar concept to Machinima which uses 3D computer game environments to quickly and easily create an animated film on a normal computer.

Although with off-line rendering over longer periods, these animations could be of far better quality and realism.
