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)
