JS errors with the viewer

[webdada]

Great work on the viewer !

I just download the viewer as a zip, tried it directly on Chrome browser, and also deployed to Tomcat and run it as a web app.

I got some JS errors, and the 3d scene would not load (blank screen).

My bad. Looks like I moved some files around. Will look into this and
report back/fix...

Doh! I renamed 'libs' to 'lib' - forgetting it was used here of course.

If you update your code, this simple rename should fix things.

I will update the source later today.

BTW, this is all very old code. There are now easier and simpler ways of
doing things.

if you have a sample of files online, I can show you some more effective
ways.

Hi, Theo,

You guys rock!

Yes updating the 'libs' to 'lib' for readme-reader.html file seen to fix
the immediate error. However the index.html page still give me the
following error.

three.min.js:150 THREE.WebGLRenderer 82

Btw, my current project is using IFC file formats, here is a link to a few
IFC sample files. I am able to deploy BIMServer.org and have everything
working, but it was not able to handle big IFC files (100mb for my 16gb
memory java server). That is why I am trying to see if there are other ways
to display and edit AEC file formats, IFC for me mostly, Revit would be
really nice - but I am also running into dll reference issues in Visual
Studio when I tried it this morning, most likely related to my Revit 2017
dll and exes, again my main focus is IFC at this point so we can work on
one issue at a time :-)

@webdada

This new set of errors is because that vA3C viewer is set to load the latest version of Three.js. And, guess what, Three.js has changed a lot.

So I have added to my task list, the task of fixing the viewer only to load the antique revisions it was comfortable with those many years ago.

But let's get back to your issue - viewing IFC files.

I have looked at the data for HelloWall.ifc and HelloHouse.ifc and the format is tedious but not complicated.

I also looked here for free, open source IFC 3D viewers that run in the browser,

http://www.buildingsmart-tech.org/implementation/get-started/ifc-toolboxes/ifc-toolboxes-summary#IFC_geometry_viewers

But all the apps want to be downloaded - which seems very old-school to me.

Oh, I now see this one: http://www.ifctoolsproject.com/ - last updated 2013 and perhaps some others as well - but nothing that's on GitHub, has no strings and is just simple.

Am I missing something - seeing some cool IFC apps - that are out there somewhere?

If I build an IFC 3D viewer with Three.js that reads the two samples can you supply more complex models?

[webdada]

Yes there are some cool IFC apps out there.

OpensourceBIM server

and BIMVie.ws viewer (I think it might be using three.js already, from some
of the notes I saw).

https://github.com/opensourceBIM/BIMserver

Here is a 70mb model running on my laptop using opensourceBIM server.

[image: Inline image 1]

I want to provide this information to you so that I will not be wasting
your valuable time. But there are quite a few things to be desired from the
BIMvie.ws project:

1. Editable IFC file -> once the IFC file gets translated to JSON
   (three.js), even if we are just updating non-spatial attributes, it can not
   be saved back to IFC - or can it be ?
2. Redline the IFC model , etc.
3. Lastly, is there any possibility that we can divide AEC models (Revit or
   IFC) into tiles and stream the models - I mean like how GIS does it -
   Google Earth Enterprise divide the global into some 9 levels of tiles, each
   is about 9x9 grids, so at any moment we are only viewing a small fraction
   of the entire globe.

Anyway I mention this so that if we do develop a new IFC js viewer/editor,
it can be THE BEST one :-)

Regards,

Sam

@webdada

Image did not make it.

BIMvie.ws looks like really complicated stuff. And I could not get it to load anyway - something about issues with a plugin.

Anyway, I am thinking about something smaller more hackable. Something easy enough for an engineer or designer to edit themselves.

> 1. Editable IFC file

If you are talking about opening an IFC file, viewing it, editing something using the browser and saving back to an IFC file.

Then, I don't see why not.

If its about updating data on something like bimServer then that can get complicated and is most likely above my level.

> 2. Redline the IFC model , etc.

If we can do 1, then we can redline in any color you want.

>3. Lastly, is there any possibility that we can divide AEC models (Revit or
IFC) into tiles and stream the models

That depends on what you are trying to accomplish.

If it's about reducing file size that depends so much on how the models are built.

If, however, you are talking about viewing then there's a lot of fun stuff you can do with Three.js to section and explode views.

I will come back in a day or two once I've had a go at viewing the two sample IFC models. By then I should know quite a bit more about what is doable.

BTW, if you like tiled maps, here is a work in progress: https://jaanga.github.io/terrain3/elevations-core3/

Okay it looks like Github email server is doing something ...

I have share this folder, which contains 1. the Bimvie.ws image 2. An IFC
file which is an export of the Revit sample file.

https://drive.google.com/drive/folders/0BxGGtjhrE11IbHVzS0J0STZuM1k?usp=sharing

Also in Revit, you can export any .rvt file to IFC file, by using the
Export --> IFC menu option.

The data looks like it will be a fun puzzle to crack. and it won't happen overnight. ;-)

IFC View R1

@webdada

1. Are there any aspect of the IFC files that we should be concentrating on? In other words what should I be looking to do in the next release or two?
2. Are there any good sources for the IFC format info? Most sources read like gobbledygook and take forever to load.

IFC View R1

IFC View Read Me

Concept

• IFC is an emerging AEC standard
• Many apps are proprietary and closed source

• Provide interactive 3D views
• Entry level code accessible by engineers and architects

Thanks Theo -

1. IFC4 Specification
   http://www.buildingsmart-tech.org/mvd/IFC4Add1/RV/1.0/html/
2. I have include my comments below - just my two cents.
   Concept

Industry Foundation Classes (IFC) is the open and neutral data format for
openBIM.
Many open and closed source apps are not web-based.
Many apps translates IFC to other formats for visualization, storage and
query
Mobile apps also have similar challenges, including IFC to other format
translation.

Mission
Build lightweight IFC apps that work in your browser
Provide interactive 3D views
Entry level code accessible by engineers and architects
Basic IFC property editing capability
High Performance viewing based on streaming or gradual loading of different
layers - instead of loading everything at once.
Ability to Redline IFC models
