Command Line 6.2.10

3.116. 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)

Result:

Result of surface function
