Blend4Web: a 3D Web Framework

Blend4Web is a tool for interactive 3D visualization on the Internet. Our framework is well suited for showcasing products, e-learning, game development, advertising and webdesign.

The major distinguishing features of Blend4Web are:

• It works right in the web browser without installing any plug-ins (WebGL technology);
• Not only does it render 3D graphics but it also integrates realistic physics and spatial audio;
• It is extremely simple to use because it is based on Blender in which 3D scenes can be made and then directly exported, even as a standalone web page;
• It is available as a fully functional open source version or as under a paid commercial license.
• It does not depend on any non-free components or cloud services.

This repo mirrors the community edition SDK distribution which can be also downloaded from the official site.

You need a compatible version of Blender installed in order to use Blend4Web.

Step 1 - Specifying Blender Scripts Path

• Run Blender, load the default scene File > New;
• Open the user preferences window File > User Preferences...;
• Go to the File tab, choose the path to the blender_scripts directory in the Scripts field;
• Click Save User Settings and restart Blender.

Step 2 - Enabling the Add-on

• Again load the default scene;
• Open the user preferences window;
• Go to the Add-ons tab and select Import-Export. Turn on the Import-Export: Blend4Web checkbox;

• Click Save User Settings. Restarting Blender is not required.

What is Next

To reveal the engine settings, select Blend4Web from the upper panel menu.

Fast Preview

Preview scenes using Fast Preview button, located both at the bottom of the 3D View window and under the Render tab. In this case the scene will be exported inside some temporary storage and opened with the Viewer.

Export

Select either Blend4Web (.html) or Blend4Web (.json) option from the File > Export menu.

Exported HTML files are self-contained and can be opened with a generic browser right away. On the other hand, exported JSON (together with BIN) files should be opened with the stock Web Player or loaded into your own 3D web app. See the tutorial.

SDK Index Page

Under the Render tab click SDK Index. The SDK index page will be opened in the default browser. Look through the demos, read the docs, run the Project Manager.
