Release of 1.13.2

Dear friends of JSXGraph,

JSXGraph v1.13.2 is a patch release that resolves several bugs, and - somewhat unusual for a patch release - comes with a few new features and API changes.

The API changes are

• Homogeneous Coordinates: The methods surface3d.F and surface3d.evalF now return homogeneous coordinates. These are arrays in the form [1, x, y, z], making them compatible with 3D transformations.
• JXG.appBox Configuration: The JXG.appBox feature (introduced in v1.13.0) now expects cssStyle instead of style as the key name for JSXGraph board attributes.

New features

• curve.getCoords(): A new method that returns an array of coordinates for a curve.
• 3D Enhancements:
  • The default style for 3D front planes has changed to a “frame style.”
  • plane3d can now be triangulated.
  • Camera distance handling is now synchronized for both parallel and central projections.

Bug Fixes

• 2D Plotting Regression: Clipping of curve screen coordinates has been reactivated and improved.
• Other Fixes: Various issues have been resolved, including the correct handling of media query listeners.

For a complete list of changes, please refer to the CHANGELOG.

Enjoy, Alfred
