Bezier library for OpenScad

thingiverse

IMPORTANT This library is user friendly. It's much harder to use without the SVG to OpenSCAD InkScape extension. See: https://www.thingiverse.com/thing:2805184 Another useful tool to create incredible models with OpenSCAD. I added a module to create multiple polygons from lists of points and bezier handles. The modules provided by the original version (http://www.thingiverse.com/thing:8483) are nice when we're trying to control how triangles will be split, but they're not useful when trying to create a polygon to use with rotate_extrude. The only modifications I made to the original library were adding the module bezier_polygon to create a single polygon from a list of points and fixing a few deprecated usages. [2017-03-13] I updated the BezPolygon module. I added a boolean parameter to show the points and bezier handles. Those are quite useful when drawing a complex polygon manually, or when editing one. This feature is not intended for rendering. [2017-03-19] I changed the "drawHandle" parameter (boolean) for "handleOpacity" (value from 0 to 1, default 0). I found it more useful that way. [2017-03-24] Added BezPolygonCoordinates function which returns an array of coordinates that can be used to create a polygon. I added this function because I couldn't find a way to send a polygon as a parameter to a module or another function. Polygons cannot be stored in a variable, but an array of coordinates can. NOTE: I just discovered the children() function which does exactly what I wanted, thanks to Kintel (#openscad on irc.freenode.net). I don't need BezPolygonCoordinates anymore, but I will leave it there because it may become useful at some point. [2018-02-25] Uploaded v2, with fixed module names and improved comments [2019-07-20] Added bezier_stroke Instructions Download bezier_v2.scad, put it in the same folder as your .scad file. Import the bezier library with include Create your polygon using bezier_polygon Extrude the polygon the same way you would do with a circle or a square. Look at demo_v2.scad for a simple example.
