#include <ClanLib/core.h>

Construction:

CL_BezierCurve

Constructor

Attributes:

get_steps	Returns the number of steps
get_cs	Returns the number of curve segments
get_stepping	Returns whether steps is the number of points per segment or per curve.
get_length	Returns the lenght of a segment (or the curve)
get_curve	Returns an array of cs * steps CL_Vectors -> the curve
get_control_points	Returns the 4 * cs control points

Operations:

set_steps	Sets the number of steps
set_stepping	Sets the stepping

Operators:

operator []

Returns the n-th vector of the curve (_doesn't_ return a reference)

Detailed description:

This class generates points on a Bezier curve from given control points

USE AT YOUR OWN RISK TILL THIS CLASS IS EXTENSIVELY TESTED!!! I WILL REMOVE THIS WARNING ONCE IT BASICALLY WORKS.

I hate documentation work and I won't document this code before any one besides me actually uses it. So if you want to use it simply write a mail on the ClanLib User list and I will do what I can :-)

  1999/12/30	vogel       renamed CL_Bezier to CL_BezierCurve
                          added CL_BezierSurface

  1999/07/07	vogel       initial version


  BezierCurve TODO: 

  - length and stepping per curve

stepping per curve means that the generated points are equidistant to each other and this requires get_length() working. So at the moment all that is working is having 'n' equidistant points per segment.

same applies to BezierSurface.
