Baked physics animation

[Ttiki]

Hi everyone. 

 

I'm thinking a lot about baked physic simulation lately in a broad sense. I've been looking inside how different game engine handle this baked simulation. Like for exemple

"In Source, baked physics animations typically get streamed in from ANI animation files" - Valve Developer Community

Or (Warning: I've never used Unity and don't know a thing) but like this tutorial for Unity : 

 

And I could give make a state of the art for different method for different engine but you get the point... I don't think I never needed to make my point in the first place as most of you already know what baked physic simulation is...

 

One heavy and "old" way of doing it is vertex animation of course, allowing for "every" kind of simulation to be baked and easily readable by software. Just move each vertex for each frame. But yeah, not the most optimised way... 

And, apart from simplistic cloth simulation and rigid body sim, bone simulation doesn't allow for complex animations. 

 

I would love to speak about different baking physic simulation animations technics, and we could you use this forum post to do so. And, when I've done some free time on my own from my Ph.D. I will probably try to do a literature review on baked physic simulation method for in-game use (Yeah, stopping state of acting from my job to my hobby, what a great idea... I have nobody in my life, help)

 

One thing I wanted to know (and I always I just goes and goes) but (if I set up this post correctly) I wanted to see and maybe talk about your experience with baked phys sim inside Leadwerks.

I'm not interested in ULTRA for this poll as of yet, even though that is something I will visit eventually.

 

I'm eager to see the results and maybe talk with you about your implementation of BPS animation in Leadwerks (and in general)
