These are thoughts about V3 of JSCAD, which includes API breaking changes across several core libraries. In addition, applications may need changes in order to support core library changes.

Packages

  • switch to Rollup (replace browserify) to package libraries with UMD / ES6 import bindings
    • NOTE: web UI cannot use Rollup due to webworkify / most libraries
  • publish UMD / ES6 librares

Modeling

  • NEW add dependency on array-utils (and drop duplicate functions)
  • Rework poly2 into a complete geometry
  • Rework geom2 into a list of outlines
  • Move slice to geometries
  • Remove Orthonormalbasis (rework functions that used Orthonormalbasis)
    • ALTERNATIVE: create 'basis' object for providing to/from matrices
  • Rework vectorChar() and vectorText() to return array of path2 objects #1067
  • Allow empty / sparse lists in all operations
  • Unify offset and expand, and add a new parameter to control
  • Correct parameter names which are not camelCase
  • Remove axes parameter for ellipsoid (rework expand 3D)
  • Unify path2.create and path2.fromPoints
  • Unify poly3.create and poly3.fromPoints
  • NEW union / intersect / subtract for paths (See http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Paths-Combining.html)
  • NEW add support for GLOBAL segments
  • NEW add support for GLOBAL EPS
  • NEW Connectors
    • re-implement as supported geometry (anonymous object form)
      • contains plane, and perpendicular (vector)
      • created from...
        • plane and perpendicular
        • three points (of plane), and perpendicular
        • closest point on GEOMETRY to POINT, and perpendicular
    • adding attributes (name, id, etc) is possible
    • usable as parameter to transforms; align, center, mirror, rotate, scale, translate ==> transform(mat4)
  • NEW Curves (See http://verbnurbs.com/ for inspiration)
    • NEW arc
    • NEW nurbs
  • NEW pipeline operation (see https://github.com/jscad/csg.js/issues/114 )

IO and Sub-packages

  • Drop AMF support / code
  • Drop GCODE support / code
  • Drop SCAD support / code
  • NEW functionality for converting external formats to JSCAD (separate functionality from Core)
  • Package and publish all IO libraries

Core

  • NEW 'use' function to include / evaluate a single source file (remote loading)
  • Rework evaluation to support async functions, both cli and web
  • Rework to use NEW IO functionality
  • Rework to remove AMF support (if needed)

CLI Application

  • Rework to call main asynchronous
  • Rework to remove AMF support

Web UI Application

  • Create reusable viewer components
  • Rework to call main asynchronous
  • Rework to remove AMF support

Renderer

  • Adjust viewer for geom2 changes
  • NEW conversion and rendering of slice
