// Cam/follower mechanism simulator by Jumpjack
// 0.5.0
// Fixed major bugs of angle-driven profiles, but yet to be finished (angle file to be loaded/saved separately from cam file)
// Fixed some bugs in profile dragging management
// 0.4.0
// Added draft manual editing of flat profile, to be fizxed first marker
// 0.3.0
// Added rotating follower; use profileType at beginning of source to change follower type.
// 0.2.1
// Bugfixes for JSON import
// Bugfixes for profile smoothing
// 0.2.0
// Fixed bug of center hole not at center
// Fixed bug of cam profile drawn from top/border rather than from bottom/center
// Fixed bug of reversed cam rotation
// Added circular zoom feature
// Added full calculation at once of pressure angle curve (realtime and commanded)
// 0.1.5
// Added reference hole at center
// Version 0.1.4
// Added pressure angle path (hence circular cam moved to the right to get some space)
// Fixed bug of bad calculation of follower contact point;
// Added orange colorization for invalid concatc point of follower
// Added cam eccentricity (= follower horizontal offset); to do: fix flat path marker for eccentricity !=0
//
// Version 0.1.3
// Added flat path markers
// Added display of rotation angle value
// Added slider for manual rotation
// Added import/export SVG
// Grouped import/export buttons
// Cleaned up code
// Increased resolution of circular path (indepdendent of flat path resolution)
// Version 0.1.2
// Added exporting to SVG format.
// Please use one of these servies to convert to STL for 3d printing:
// https://rawgit.com/ryancalme/svg-to-stl/master/SVGtoSTL.html (source: https://github.com/rcalme/svg-to-stl )
// http://svg2stl.com/
// Version 0.1.1
// Added pressure angle
// Version 0.1.0 - First public version - 11/11/2021
// To do:
// editable flat path;
// export in SVG format;
// export in STL format;
// tunable rotation speed/direction;
// add speed chart, angle chart, acceleration chart,...
// Known problems:
// Can't handle properly two points at same angle in flat path
