For years I have wanted to port vZome to the web, for several reasons. The most important reason is the ubiquity of the web as a platform, of course, which means that web applications are available to everyone on the Internet, with no installation step required.
Now, the goal is in sight. I have a “classic” variant of vZome Online that is starting to approach feature parity with desktop vZome. Along the way, I’ve implemented a number of web applications using the same core software. This page is an introduction to the whole menagerie; most of the headings below are links to the applications being described.
This application is intended to be a faithful port of desktop vZome to the web, preserving almost all aspects of the desktop user interface for the sake of familiarity. It can already open and save vZome files, and so is fully interoperable with desktop vZome. However, it still has a long way to go; the most glaring omission currently is a strut building tool. Check back often, or join the Discord server to see updates, as vZome Online Classic is continually improving.
This is a proof-of-concept – an experiment in providing a more intuitive experience for building struts in 3D space. It accomplishes this by restricting you to a 2D plane, with gestures to change the plane. I intend for this to be the centerpiece of a new vZome Online, one that has a modern UI more in the style of Desmos or Geogebra. For now, it is fun to play with. Even so, it already supports saving designs that you can open with desktop vZome 7.1.14 or later.
This URL will be the eventual home of the main vZome Online application. For now, it hosts an application that allows you to open and view vZome designs on your computer or from the internet.
The vZome Online Web Component
In many ways, this is the most important application, and it is not a single application in any sense. I have wrapped the core vZome Online technology as a web component, which makes it nearly trivial to embed interactive 3D vZome designs into any web page, blog, e-commerce site, or whatever.
Here is the essential HTML for the figure above:
<script type="module" src="https://www.vzome.com/modules/vzome-viewer.js"></script> <vzome-viewer style="width: 100%; height: 60vh" src="https://vorth.github.io/vzome-sharing/2021/09/11/10-10-11-rose-olive-bombshell-solid/rose-olive-bombshell-solid.vZome" > <img style="width: 100%" src="https://vorth.github.io/vzome-sharing/2021/09/11/10-10-11-rose-olive-bombshell-solid/rose-olive-bombshell-solid.png" > </vzome-viewer>
<vzome-viewer/> custom tag, which does all the
heavy lifting of loading the vZome model and rendering it in a 3D viewer. Only one such script tag is needed per page,
no matter how many viewer elements appear on the page.
The web component plays a huge role in vZome desktop’s mechanism for sharing designs via GitHub. You can see the power of this sharing feature when you look at my geometry blog, and even more when you browse John Kostick’s. A number of other vZome users have set up their own sharing website; follow the simple instructions, if you’d like to do the same.
This is a utility that comes in handy when sharing vZome designs via GitHub as described above, or more specifically, when composing web pages that show multiple designs. A common pattern is to export a web page when sharing one design, then enhance the page with more designs already shared. This browser helps you find those existing designs and grab the HTML snippet to include them in any web page. I used it when writing this web page!
By default, the app will display my own GitHub repository, but there is a selection control that lets you choose from a few others. Whatever you select, the app will save your choice in browser local storage, so that choice will be pre-selected the next time you open the app with the same browser.
To display another GitHub user’s (e.g. your own) designs, click on the “X” in the editable selection field and type the GitHub username. The username will be added to the list saved in browser local storage, so the list of possible users will grow over time.
If you ever need to delete a bad username from the list, just bring up the browser’s developer view, enter the “console” tab, and view and modify the saved values as follows:
> localStorage.getItem( 'vzome-github-users' ) '["vorth","david-hall","John-Kostick","ThynStyx","pdmclean","tomgeometer","roice3","pfreire163"]' > localStorage.getItem( 'vzome-github-user' ) 'vorth' > localStorage.setItem( 'vzome-github-users', '["vorth","david-hall","John-Kostick","ThynStyx","pdmclean","thynstyx","tomgeometer"]' )
The values are always strings, so be careful with those quotes!
