Sketchfab is a new web service to show and share 3D content. It allows publishing interactive 3D content online in real-time without plugin.
Sketchfab doesn't require any third application installation to work, you just need a WebGL compatible browser.

The service supports uploading 3D models in 25 supported formats, including Blender, 3DS, Wavefront, and Lightwave.
You can embed your 3D models on your website or share it on Facebook.
