Blender Addon - Export Curve to JSON

A simple exporter to write curve data to JSON. In the export panel, you can convert to your desired forward and up axes and specify whether the positions are in world or local space.

Currently, it exports the following data:

• Export Settings
  • world space coordinates
  • up & forward axis
  • units
• Curves Data
  • object name
  • type (Poly, Bezier, Nurbs)
  • spline length
  • cyclic u & cyclic v
  • points data
    • tilt
    • radius
    • position
    • handles (only if type is 'Bezier' )

For now, animations and shape keys are not included.
