Getting started with models

[Neil Mitchell]

Hi,

Sorry for what I'm sure is a very newbie question.

I'd like to produce a model of 3D fossils on a bedding plane, which is essentially a surface combined with 400 or so small spheres. I have x/y/z coordinates for everything, but I have no idea how to turn them into an open-3d-viewer compatible model. Is there any recommended program to use, any docs on the format or similar?

Thanks, Neil

Hi Neil is nice to hear from u. Now concerning open 3d, well the thing is the project was done by some guys so they can use it in their project so when it comes to doc am sorry it is limited.
First of all u need to export the model as an obj file. Second there is a website that will help u compress ur model to utf8 files the problem is it has been sometime since i worked with open 3d so I no more have the site but search through the google groups I thing the site is there. Also I have created a python script that help u generate the entity metadata which describe ur model. Again seach the group u will get the script

If need be I will try and create some tutorial for u but for now try to do it ur self.  :)

And don't worry about newbies every body have been one before even I still am.  :)

Thanks for your help. With your suggestions I managed to get something
working. I've got to do some refinement tomorrow, but I intend to
write a blog post about the steps I followed, and hopefully you can
steal some of that for your documentation.

Thanks, Neil

Hi Neil,

sounds like you're all set, but https://code.google.com/p/webgl-loader/ has some notes on how producing the utf8 files (it's linked from the open-3d-viewer page, but not very visibly). Looking forward to your blog post :-)

Hi All,

I've written up the steps to producing a 3D model here:
http://neilmitchell.blogspot.co.uk/2014/09/generating-open-3d-viewer-models.html
- following those steps, I've generated a number of models quite
happily. It's a nice tool, and I'll be making a few public viewer
instances based on it over the next few months.

Nico: I found the webgl-loader pieces, but had limited success with
them. The page says "use r50". When using r50 I got part way (I didn't
succeed, but that may have been due to errors later on which I
subsequently resolved). Using the latest version I got segfaults when
running (seemingly library/startup related, possibly due to my g++).
Either way, it didn't get me to the end. The binaries I found are
presumably webgl-loader ones, but taken from the right point in time,
and compiled in the right way.

Thanks, Neil
