Creates points that form a shape defined by parametric math expressions.
The math expressions can use the variable u. This node calculates each expression for evenly spaced values of u 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 time
variable (with a lower-case “t”) is used in the expressions.)X Expression
, Y Expression
, Z Expression
— The math expressions for the (X,Y,Z) position of each point.Subdivisions
— Each of the above expressions is calculated for this many values of u. This is the total number of points created.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 Calculate
(vuo.math.calculate
) node’s description.
For help understanding the math used by this node, see Introduction to parametric equations.
