Creates points that form a shape defined by parametric math expressions.
The math expressions can use the variables u and v. This node calculates each expression for evenly spaced values of u and v ranging from 0 to 1. Each calculation becomes one of the resulting points.
Time— The time at which to calculate the expressions. (This only affects the output if the
timevariable (with a lower-case “t”) is used in the expressions.)
Z Expression— The math expressions for the (X,Y,Z) position of each point.
Columns— Each of the above expressions is calculated for this many values of u and v. The total number of points created is
rows X columns.
The math expressions can use numbers, operators such as + and -, functions such as sin(u) and log(u), and the constant PI. For a complete list of the operators and functions available, see the
vuo.math.calculate) node’s description.
