Describes a surface in 3D with two independent variables running over two different intervals.
You can integrate an arbitrary set of parameters in the formula.
Numbers of values for both variables used in the function calculation.
An array of three strings describing three functions, each of the which represents a component of the surface that this node describes. The formula can contain any number of valid variables.
Entering Valid Variables
This node accepts variables that use the following format rule: variables must start with a letter or an underscore followed by any number of alphanumeric characters or underscores.
Example of Entering Values for formulas
As an example, consider the ellipsoid given by
Setting the parameter values in parameters as a = 1, b = 2, and c = 3, you can enter the following three equations in formulas to get x, y, and z values of the ellipsoid:
a*cos(x1)
b*sin(x1)*sin(x2)
c*sin(x1)*cos(x2)
where x1 and x2 are the two specified variables.
Start values of the variables in the interval where this node starts calculating values.
This input can contain only two elements. Otherwise, this node returns an error.
Default: [0.00, 0.00]
End values of the variables in the interval where this node stops calculating values.
This input can contain only two elements. Otherwise, this node returns an error.
Default: [1.00, 1.00]
Names of the variables.
Variable names must start with a letter or an underscore followed by any number of alphanumeric characters or underscores.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Variables and their corresponding values in the parameters.
Name of the parameter that uses the conventions of the Parsing nodes.
Default: Empty string
Value of variable.
Default: 0
y values at the grid points.
These values are calculated on a 2D grid defined by the discrete values of variables. The number of elements in y equals to the product of the numbers of the two elements in number of points.
z values at the grid points.
These values are calculated on a 2D grid defined by the discrete values of variables. The number of elements in z equals to the product of the numbers of the two elements in number of points.
Error information.
The node produces this output according to standard error behavior.
