Oh wow! This is a really stunning use-case for VR, which opens up 3D modelling and artistic creation to non-programmers & artists.
Being able to create this way in 3D space, virtually moving and manipulating your creation would be so freeing. I can imagine losing all sense of time and becoming totally engrossed in the creative process.
And them, sending your creation to a 3D printer! Amazing.
Not only would non-professionals and non-artists get so much from this software, but so too would model creators, character designers (both film & gaming), installation artists...there are just so many professions who could benefit.
When you see VR used in such ways, it really gives you hope for the future of the tech.
Great hunting (so excited) :)
