In this video Light Architect shows how you can destroy glass windows or any other kind of 3d object using particle systems and an explode modifier along with some other techniques. This is a really good way that you can realistically destroy 3d objects in Blender for vfx live action shots or animations.
I am a cinematographer based in Los Angeles. I have been using Blender for many years now in creating basic 3d VFX for films. I am one of the creator's of an asset based add-on for blender called LightArchitect (www.lightarchitectaddon.com) that allows pre-visualization of Industry Level lighting and camerawork inside of Blender.
