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 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.
For help understanding the math used by this node, see Introduction to parametric equations and Introduction to parametrizing a surface with two parameters.
