Hi all, I am a student in my final year at uni studying computer games art, i am starting to research interactive and destructible environments for games from an art perspective as my final year project. I am posting on here as i have become a little stuck in regards to researching how models for interactive and destructible assests such as building walls work etc... i am curious as to how a game engine such as frostbite BF:bad company creates this effect.

So far i have looked into Morph targets but im pretty sure this is not the way it works, LoD models and basically replacing a model once a collision box is hit.

If anybody has any resources or has hands on knowledge of Interactive and destructoble/deformable envrionments used in todays games, i would love to hear from you. You will be credited in my work for any help i recieve.

Many many Thanks.

Dont know if this would be of interest its about geo mod which is used in red faction -

maybe this has some interesting infos for you.

The clasic way to destroy a model (like a car) would be having multiple models I guess and swaping on event. Maybe a a few debris particles and particles to the mix to cover the swaping.

You could also cut a objects faces up (maybe with a crack map), seperated them and extrude the parts to the inside to give them thinkness. Thats what Id do in Maya.

Thank you both for the replies, this will definetly aid in my research for my dissertation , that apex engine looks amazing its nice to see UT3 being blown to bits heh.

Research this: Portal-Octree Hybrid

This rendering method is good for dynamic environments. Now this isn't a game engine, this is the idea upon many game engines are built on. Good luck with your research.
