3.112. surfaceFunction command
Description: This option creates a surface by defining two parameters and three functions.
Inline mode usage:
- surfaceFunction -h: Displays the help file that summarizes the parameters for this command.
- surfaceFunction –n <name> -p <u_start> <u_end> <u_samples> <v_start> <v_end> <v_samples> <x=f($u,$v)> <y=f($u,$v)> <z=f($u,$v)>: Create surface with three functions that defining points in cartesians.
Interactive mode usage:
- Invocation: surfaceFunction
- Parameters:
- Parameter “u” (start end samples) in order to define range of variable “u”.
- Parameter “v” (start end samples) in order to define range of variable “v”.
- x = f($u,$v) for X coordinate function
- y = f($u,$v) for Y coordinate function
-
z = f($u,$v) for Z coordinate function
- Remark: The parameters u and v of the functions are bound to the variables $u and $v.
Example:
>surfaceFunction
Parameter ‘$u’ (start end samples): 0 24 48
Parameter ‘$v’ (start end samples): 0 24 48
x = f($u,$v) = $u
y = f($u,$v) = $v
z = f($u,$v) = sin($u) + sin($v)
