Vector Fields

See a vector field standing in the room in front of you. Vector Fields turns any three-component vector field into arrows you can walk around. Type something like -y, x, 0 and it appears in augmented reality, drawn in the space in front of you at true scale. Built for anyone learning or teaching multivariable calculus, where the hardest part is often picturing what a field actually looks like. Rotation, divergence and flow stop being abstractions once you can lean in and look along an axis. WRITE ORDINARY MATH Expressions are ordinary notation, not code. Implicit multiplication works, so 2x, 3sin(y) and (x+1)(x-1) all parse. Powers use ^ and are right associative. Odd roots of negative numbers give real answers, so (-8)^(1/3) is -2 rather than an error. Supported throughout: sine, cosine, tangent and their reciprocals, inverse and hyperbolic forms, exp, natural and arbitrary-base logs,…
