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*. 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 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)* - Constants such as
*PI* - Variable
*U*— evenly spaced values ranging from`U Min`

to`U Max`

- Variable
*I*— the integer index of the point, ranging from 1 to`Subdivisions`

For a complete list of the operators and functions available, see the Calculate node’s description.

For help understanding the math used by this node, see Introduction to parametric equations.
