WebGL

Intro

WebGL (Web Graphics Library) is a JavaScript API for rendering interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins.

Update

First explosion view model on gitlab and embedded.

• The code https://gitlab.com/mi_shell/models_online/tree/master/ose_webgl
• The model https://mi_shell.gitlab.io/models_online/ose_webgl/d3d_explosion.html
• Embedded https://wiki.opensourceecology.org/wiki/Michel_Log

Example

Primitive example from Aidan Log

Playing around with WebGL stuff. Here's a VERY primitive workflow:

1. Starting with A2+ assembly file
2. Select all on object tree
3. Export to WebGL.
4. Put resulting .html file in a folder with a subfolder containing three.min.js
5. Open resulting .html file in a text editor
6. Edit three.min.js source as per Michel's instructions
   1. Also can add antialiasing if desired. See video:
   2. 
7. Optional: make an index.html file. Embedding the index seems to be more stable.
8. Create a github.io page
   1. In your github account: Make a new repo with name username.github.io
      1. My username is CabbageBreath
   2. Upload your project files to that repo
   3. https://username.github.io/modelname.html is where the project will be hosted.
   4. Mine is cabbagebreath.github.io/Index.html This produces the below render if you embed it using an iframe

Note: Embedding the file directly worked for a few hours then starting giving 400 bad request errors. Embedding the index.html seems to be a better option for now.

• Michel,

Do we have any documentation anywhere that describes how to go from a FreeCAD file -> WebGL model like the one on the OBI website:

Your work looks really amazing! We're launching an Open Source Everything e-commerce store for selling our products, such as the D3D -- Open Source Ecology's 3D Printer. We would love to add corresponding WebGL models on the product pages so customers know exactly what items we'll be shipping them and how it will be assembled.

Is there some automated process for generating these files like dat.gui.min.js?

Or does it necessarily involve lots of iterating & expertise with FreeCAD, Blender, Gimp, and coding in JS?

Hi, it's taking a bit longer than anticipated but one of these days the webGL template will be ready. I had to get used to the new setup and test the new features of the exporter.

A little preview in attachment. Cheers,

Michel.

Process:

I already added some things to software list. Brackets which is a pretty good open source web code editor and the ThreeJS exporter for Blender. To make it easy...

1. Start Blender
2. go to File>User Preferences...>Add-ons
3. click the button on the bottom "Install from file..."
4. install the zip-file in attachment
5. click the selection box next to "Import-Export: Three.js Format"
6. click the button on the bottom "Save User Settings"
7. done...
8. Install brackets in Linux.
