paramCurve

This function lets the user define a parametric curve by giving an expression that gives x for s, y for s, and z for s. For example, to draw a sine wave:
x_of_s=s
y_of_s=math.sin(3.141598*s)
z_of_s=0
s_range=0,1
The expressions are evaluated using a python interpreter. A fixed number of s values will be evaluated for (x,y,z). The first and last s evaluated are given by s_range.

x_of_s : String
Expression to give x for every s

y_of_s : String
Expression to give y for every s

z_of_s : String
Expression to give z for every s

s_range : String
Lower and upper bounds for s, separated by a comma
