OpenScad Bezier Function with Ribbons

thingiverse

This text presents an updated version of a program incorporating changes to the Bezier functions. It now includes a 3-element version of PointOnBezCubic() for 2D and 3D usage, with examples demonstrating x, y, z, or r, g, b values in pictures. Additionally, it features an example of using color with the bezier curve to add ramped color goodness to images. The code has been factored and commented for better understanding. The main purpose of these updates is to create BezierStrips, which can be made by giving the function two sets of control points (4 points each) to generate an extruded strip between the curves. Applications include creating handles for cups, funky-looking springy feet, and vertical ramps for skateboard parks. The text also shows a bell-shaped object made with BezierStrips by rotating it around the z-axis. The author expresses delight at OpenScad's rendering capabilities. An update link is provided for more information on this design. The instructions suggest using graph paper to layout control points, and then plugging them into either the BezCubicFillet() or BezCubicRibbon() modules to generate desired shapes, resulting in 'Bez'ness rejoicing.' The author also wishes for printers to honor color selection from drawings.
