This release is identical to v1.12.1, only a few unnecessary zip files had to be deleted. Otherwise the package size at the CDN jsdelivr would have been too large. That is, v1.12.1 is not available on jsdelivr, but v1.12.2 is.

Enjoy, Alfred

JSXGraph v1.12.1 is a patch release that adds some subtle improvements and addresses a few annoying bugs.

The update addresses the following issues (among others):

• Increased precision for intersections (points) of curves with curves or lines
• The output format of polyhedron.toSTL() is now correct
• Some smartlabels were broken
• The handling of attribute frozen is further improved
• Improvement of the API docs
• Security: replaced some innerHTML by innerText
• Arrow heads in SVG take the CSS color of the line
• jsxgraph.css now contains a version string

In particular, the change of the intersection algorithm for curves might cause problems in existing constructions - even if we tried to make it as backwards compatible as possible. Please report any issues with intersection points, we will try to find a solution.

For the full list of changes see CHANGELOG.md.

Enjoy, Alfred

JSXGraph v1.12.0 mainly improves 3D functionality: it is now able to read and write polyhedra in the STL file format (ASCII only, so far), 3D transformations have been further improved.

JSXGraph has updated its logo. It can be downloaded in many flavors from the new designed homepage https://jsxgraph.org. The copyright string is now much shorter and contains the new logo. With the new board attribute showLogo it is possible to show just the logo.

The use of the attribute frozen which makes the position of elements independent of the zoom level is now much simplified. This is useful especially for sliders. Implicit curves are now clipped and don’t overlap their domain anymore.

Additionally, 3D performance could be improved and multiple bugs were fixed.

Enjoy, Alfred

JSXGraph has a new look and it’s more than just a facelift:

The JSXGraph logo comes in three layouts (text, square, banner) each suited for different uses. Download the various logo files and versions here.

Evolving the JSXGraph Logo

The JSXGraph logo has undergone a thoughtful redesign—one that remains rooted in the mathematical essence of JSXGraph while embracing new dimensions, both literally and conceptually.

At the heart of the new design is the familiar graphical element of the JSXGraph board.

It continues to serve as a visual anchor, preserving the connection to JSXGraph’s core identity.

What sets the redesign apart is the introduction of a subtle 3D component—an elegant nod to JSXGraph’s evolving capabilities, particularly its support for three-dimensional constructions and visualizations.

This updated visual identity does more than refresh the look. It reflects JSXGraph’s broadened scope in dynamic, interactive mathematics—while staying anchored in its foundational concepts.

The circle continues to represent the domain of interactive geometry, highlighting JSXGraph’s strength in constructing and exploring geometric figures.

The coordinate system, in turn, stands for the representation of function graphs and curves, emphasizing the framework’s capabilities in plotting and analyzing mathematical relationships.

The new logo stands as a forward-looking symbol of JSXGraph’s mission: to make mathematics interactive, multidimensional, and accessible—empowering a new generation of learners, educators, and innovators:

JSXGraph v1.11.1 is a patch release that addresses a few subtle bugs.

The update includes fixes for the following issues:

• Removing 3D objects is now handled correctly, resolving a potential issue that may have caused unexpected behavior.
• Setting certain attribute values has been improved.
• The handling of the null color value has been updated to properly support transparency, again.

Enjoy, Alfred

We are excited to announce the release of JSXGraph v1.11.0, a major update that brings significant improvements to 3D functionality. This new version introduces a new element called polyhedron3d, which allows for the creation of 3D polyhedra, enabling the creation of complex 3D polyhedra with ease. The element supports shading effects on 3D faces, taking the realism of your 3D scenes to the next level.

In addition, the depth ordering of 3D elements has been extended to include polyhedra, making it simpler to create convincing 3D scenes. Depth ordering is now organized layer-wise and set as attribute of the 3D view. Elements in different layers are not compared. The internal 3D element structure has also been completely refactored, improving performance and flexibility.

The update also introduces 3D transformations, making it easier to create complex 3D animations and interactions. With these transformations, you can now rotate, scale, and translate 3D objects with precision and control.

One of the key strengths of JSXGraph is its flexible attribute system, which allows for seamless embedding of constructions into any design. This flexibility has been further extended in version 1.11.0, with the ability to pass the hosting element as a parameter to functions given as values of attributes. This simplifies the creation of visualizations where colors or other attributes depend on the object’s position or other properties. See the attributes fillColor and size in this heat map example.

In addition to these exciting new features, JSXGraph v1.11.0 also includes support for all ARIA attributes in all JSXGraph elements, as well as the ability to set CSS classes bound to all JSXGraph elements. This enables the use of SVG filters, further enhancing the capabilities of your visualizations. These features are available for the default SVG rendering. New math methods have been added for handling matrices and testing of a point set for convexity. The update also includes a much-requested feature: the ability to construct curves by supplying a list of coordinates, rather than separate arrays of x-coordinates and y-coordinates. This feature has also been added to 3D curves.

Finally, the release contains numerous bug fixes and improvements to the API documentation, ensuring that you have the best possible experience with JSXGraph v1.11.0. Overall, this new release is a major step forward in the development of this powerful graphing library, and we are excited to see the new possibilities it will enable for users.

For more improvements and bug fixes see the CHANGELOG and the blog posts on the beta1 and beta2 releases of v1.11.0.

Many thanks for all contributors who made this release possible.

API Changes:

• depthOrder instead of depthOrderPoints
