Updates to Euclid’s Muse

December 31, 2013 in News

We are excited to announce some of the recent updates to Euclid’s Muse. The front page has been reorganized so it’s easier to find what you’re looking for (and it’s much nicer to look at). Join us on the new forums page and help build our community by posting your questions, comments and app creation tips! A big thanks to Nick  Halsey, our app contributor and creator of Euclid’s Muse, for making the site look great.

Euclid’s Muse is now Mobile-Friendly

July 9, 2013 in News

We’ve just upgraded our design to fully respond to device sizes ranging from smartphones to tablets, laptops, desktops, and everything else in between. While Euclid’s Muse has always been mobile-accessible, it used to be difficult to navigate, requiring constant zooming and scrolling to read text or interact with apps. Now, Euclid’s Muse is a joy to use on whatever device is handy, and you shouldn’t need to zoom in just to read the text, interact with an app, or select a link. Desktop-centric features like app uploads are still accessible, but de-emphasized in favor of content-consumption. With the responsive design update, certain display elements are now improved on larger/traditional devices as well, such as a flexible layout on the browse page.

As a bonus, we’ve added support for Linkedin sharing on apps as well as all social sharing options on blog posts like this one. We hope you enjoy these new features and, as always, let us know if you find a bug!

Geometry Expressions 3.1 Released

May 24, 2013 in News

We’ve released Geometry Expressions 3.1 (if you have version 3.0, install the update by going to the Help->Check for Updates menu). This release features many new features aimed at improving apps for Euclid’s Muse. New features include:

  • Several new features for generated JavaScript apps, Lua apps, and Dashboard Widgets:
    • New input controls:
      • Advance Button lets you increment a variable
      • Media Buttons give you more controls to change the variable
      • Random generates a random value within your specified range
      • Timer is handy for making clock apps and other animated apps
    • Outputs can now be attached to a Show / Hide Button. This feature combined with the Random input type is very handy for making practice apps where students can check their answers by clicking an answer button, then reload the page with a new problem.
    • HTML5/JavaScript apps can now include images (example).
  • Visibility Condition controls allow any object to be hidden or shown based on a mathematical condition. Use alongside the Advance Button or Media Buttons controls to generate apps that gradually reveal the inner workings of complicated constructions. (example)
  • Objects can now have constraints, annotations, and calculations applied at the same time.
  • A new export file format, Scalable Vector Graphics (.svg). SVG is the preferred format for graphics on Wikipedia; this flexible format is vector-based, meaning that the image will scale to any size needed. Look for Euclid’s Muse support for SVG uploads soon.
  • Two new built-in functions – ceil() and floor().

Introducing Collections

January 8, 2013 in News

We’ve recently launched an exciting new feature: collections. Collections allow you to group any public apps, including those that you didn’t upload, into one place. With collections, you can either view a table of contents which includes links to each app, or you can enter the collection and see each app page normal, but with links between each of the apps in the collection in sequence. Collections make it easier than ever to share math with Euclid’s Muse!

New Year, New Look

January 2, 2013 in News

To kick off the new year, we’ve updated our design to be more streamlined, user-friendly, and mobile-compatible. In addition to the design updates, we’ve released several new features, while enhancing security and boosting performance. The bottom line? Euclid’s Muse is faster than ever, and makes it easy to share and discover interactive math apps in new ways. New features include:

  • Upload .tns files — now you can upload .tns files, created with lua apps exported from Geometry Expressions, alongside your apps and their Geometry Expressions Source Files. Anyone can download this file and load it onto TI-NspireTM calculators.
  • Browse Apps with Source Files — the new browse apps with sources page lets you quickly find apps that include .gx source files, so you can play with the app online and download and manipulate its source in Geometry Expressions.
  • Browse Apps with TI-NspireTM Versions — quickly find apps that include a version that ca nbe downloaded and put onto your TI-NspireTM calculator.
  • Share to Pintrest — we’ve added one-step Pintrest sharing, alongside our existing app-sharing options, to make sharing in your medium of choice even easier.
