AMF has found its way into three.js. If you aren't familiar with three.js it is a very mature javascript library that enables developers to uniformly and easily leverage WebGL in a browser. Sites like Thingiverse, Github, YouMagine, etc all use a three.js as parts of their widgets used to render and display models for users as part of their UIs.

three.js includes a number of example loaders to help users import models from basic STLs to Collada format assets. AMF was missing. Now it isn't. :)

You can see some of the discussion at https://github.com/mrdoob/three.js/issues/7198 which is referenced in a pull request to include AMF support in the dev branch of three.js where it will eventually be included as part of the official three.js release.

three.js generally includes a model as part of an example loader. If anyone has a specific model they'd like to see in the three.js examples of the AMFLoader please let me know! My current plan is to use the three.js pyramid from the tutorial.

Awesome! Thanks Elijah. Support for viewing within Threejs is a great asset for the AMF community.

You could use the rook model (as featured in the official AMF icon) if you wanted something unique (http://amf.wikispaces.com/file/view/Rook.amf/268219202/Rook.amf). But ultimately you did the work so you can choose!

Good that its now supported in three.js though I haven't used three.js yet to
work on things. I normally stick to my own lightning fast AMF viewer :) ...
It was build to become a full blown slicer kit one day but oh well, maybe
later :) It doesn't support textures and colour gradients yet :(

Talking of viewing, the last version of AMF tools is not displaying any
rounded triangles anymore when asked to; even the ball is a regular figure
instead of a ball. Has that been explicitly disabled?

The files themselves are OK as far as I can see though I got dependency errors
when opening the more complex ones. The face worked but the others fail.

Cheers,
Reinoud

Hi Reinoud,

The curved triangles were not explicitly disabled. Looks like they got lost in the 0.9.7 to 0.9.7.1 release. For now the best bet is to just use 0.9.7.
