Impromptu Vector Field Painter

This tool lets you paint and visualise 3D vector fields in VR (or not) in real-time, inspect 'em from all directions, and save them out to .FGA format for use in whatever software, or your own games. You can also import your own existing vector fields, modify them in the tool and save them out again. This could save you a lot of time if you're already into vector fields, or make vector fields a lot more accessible if you aren't yet. 

This includes the UE4 project files, so you can make your own modifications to the tool, or, if you're working on a UE4 project, import the entire tool into your project and paint vector fields in your own environments or onto your own objects.

(A vector field is a uniform grid of vectors that can be used to influence the motion of particles. Basically, each point on this grid imparts a force on nearby particles. They can be used to make super cool effects, but they're not easy to make: typically vector fields are painstakingly authored by some arcane Maya process or generator script. That's kind of awkward! Painting them in VR is much more intuitive. )

Now supports both the HTC Vive and Oculus Rift (with Touch) VR systems, as well as a non-VR mode.
