Displaying CAD images with javascript

After a couple of days searching i decide to come here to ask if someone knows how to display 3D images (CAD images) in a website using only javascript.

My goal is to display .stp or .igs formats and allow user to interact with.

So far I've found a couple of frameworks:

https://github.com/tbuser/thingiview.js

http://threejs.org/

https://github.com/humu2009/jsc3d

But they are outdated or they don't allow me to display the formats mentioned.

Does anyone had a similar problem to this that can share how to work with?

Another possibility I've thought is to extract jpg images from the above formats and display it with a 360 image view plugin such as:

http://reel360.org/reel

http://spritespin.ginie.eu/

(to mention a few)

Pros:

Cons:

note: I don't need to have any interaction with the image such as go inside the image, make it transparent, explode... I just have to be able to display it like a 360 picture.

Do you have a nice way to achieve this?

Any comments would be helpful. Thank in advance,

André

Step and IGES are cad formats and most 3d development in webgl is game development. This is on the other side of the art/games tech divide, the CAD format does not describe polygonal models*. So any program that could show these formats would need to have a geometric solver back end called a CAD kernel. No basic 3D framework will do for you. This is on the other side of simple 3D.

STEP is also a hideously complex format doing a importer is hard even with a CAD kernel. I would look for something like opencascade for the job of converting the cad data to polygons for display. Generally speaking there aren't many free B-Rep backends.

You could also use your existing cad app to do this. I doubt you will find a pure javascript version of a CAD kernel.

* think of it like this a normal 3d model is mostly polygonal. But a B-Rep model does not describe polygons but rather the interconnection of mathematical shapes. So before you can display a step of iges file you need to solve it. Start by reading this
