Impromptu Vector Field Painter

A vector field is a uniform grid of vectors that can be used to influence the motion of particles. Basically, each point on a 3D grid imparts a force on nearby particles. Vector fields can be used to make super cool particle effects, but the fields aren't easy to make themselves: typically fields are painstakingly authored by some arcane process in 3D software or by a generator script. Painting them in VR is much more intuitive. Vector Field Painter lets you do that, and is also usable with keyb...
