While traditional 3D modeling software, either NURBS- or polygonal-based, has a multitude of functions and controls not easily transferrable into a virtual reality context, the sculting techniques could represent a very interesting application, more appropriate for the VR technology.
Yet, transferring digital sculpting techniques into a three-dimensional context poses some challenges, in particular for the need of physical feedback, required for the system interface ergonomics.
Luckily, the price of these devices, once in the thousands of dollars range, is dropping very fast.
The new haptic stylus is expected to have a price in the $500-$700 range, down from a range of $2,400 to $13,000 for existing devices.
It will be interesting to see whether this type of device will be adapted for use in an augmented reality interface.
Other independent developers are using different controllers, which may lack the physical feedback of the haptic devices, but are much more affordable.
For example, the video below shows a virtual reality 3D sculpting system that use the Oculus Rift Development Kit 2 VR headset in combination with a pair of Razer Hydra input controllers.
The perspective of virtual 3D sculpting tools appears quite promising, as it combines two different technologies – VR Hardware and 3D sculptin software – which are evolving very rapidly.
