|
independently:</p>

<p>Scans web pages for links (in text or images) to VRML or X3D files
|

(and other file formats compatible with the

|
<a href="https://create3000.github.io/x_ite/tutorials/how-to-navigate-in-a-scene/">
|
|
X_ITE X3D Browser</a>, such as glTF, obj, and STL) and inserts
|
|
"eye-cons" (👁) next to each of them. When you click the eye, it embeds
|
|
a viewer and displays the model in 3D within the page. Right-click on an
|
|
active viewer for additional options. Click the eye again
|
|
to close the viewer. Supports multiple simultaneous viewers on the same
|
|
page.</p>

Encyclopedia of Polyhedra</a> with this module enabled for a trove of

beautiful models to play with.</p>

<h2>JavaScript reinterpretation of Geometry Applets</h2>

|
<p>In the late 1990s, <a href="https://mathcs.clarku.edu/~djoyce/">
|
|
David Joyce</a> wrote a web applet in Java that allowed for interactive
|
|
draggable 2D and 3D geometry diagrams within a page. Nearly 30 years on,
|
|
Java is no longer supported for embedded applets by any major browser. This
|
|
module scans web pages for invocations of that Java applet, and translates
|
|
them into calls to the
|
|
<a href="https://wiki.geogebra.org/en/Reference:GeoGebra_Apps_Embedding">
|
|
GeoGebra JavaScript module</a>, bringing the diagrams back to life.</p>
|
|
<p>What's more, Joyce posted an
|
|
<a href="https://mathcs.clarku.edu/~djoyce/java/elements/elements.html">
|
|
on-line version</a> of the <strong>entire</strong>
|
|
Euclid's <em>Elements</em> with all of the traditional diagrams, and many
|
|
new ones of his own creation, rendered in fully interactive versions.
|
|
Be sure to give archematics a try on
