Wow. Nice to see this topic! The question on first page was about my setup. I did not see this topic before, and I just surprized why nobody noted me about this topic because I am always open to explain any of my techniques. It is just very cool research about several steps displacement for curved surfaces. I did not check current setup of Rayman, but I can suppose that it would be useful to calculate width of each step by original polygon size. Because each step means one access to pointcloud so we want to minimize that. Also I use quaternions instead of matrix because it is vector4 versus vector9 or 16 for matix

Do not forget to install Command Line Tools for XCode "1) Open Xcode app. 2) Click on Xcode > Open Developer Tools > More Developers Tools. That will take you to Downloads for Apple Developers web site. Use your AppStore Id to login. 3) Download Command Line Tools for your Mac OS X version." Or find this here https://developer.apple.com/downloads/index.action?name=for%20Xcode

Yes a lot of people are asking about english version in private messages, on the forum, in my skype but only a few people sent aplication to onlinevfx@gmail.com If you have realy plan to join a group please write to that address. When I have large group enough I will start.

Now I am starting "The Art Of Destruction 2" in russian again. It will start March 16 http://www.online-vfx.ru/course-and-masters/111-the-art-of-destruction. I am sorry but there is no english version yet. It is still in planning.

+1 for possibility of control time on object level

Update from my course English version of "The Art Of Destruction" is coming soon I hope. If you want to participate in that course please write to onlinevfx@gmail.com or almatea@mail.ru

Thanks! I did not upload it but now you can see the whole source code in the begin of this video. Really. % )

The custom solver that I write for my course. http://vimeo.com/64463947

Any chances for share a source code?

a few little breakdowns for my course 3 places for students left

Yes yes I mean same same. You have to advect by original vel field. For example for 3 times slowly: -advect original density by vel field with step 0.3333 -save density -advect original density by vel field with step 0.6666 -save density the step may be multiply of vel or timestep

you can use deep compositing, deep camera map image although if your smoke has hi density you can just use vel primitive for setting color attribute in your shader

I did it with help of custom solver that just advected density by baked velocity field. So you can make linear interpolation by advect for 1/n where n is retime multiplier.
