rayman 441 Posted June 23, 2014 Hi! I will create some examples, but they will most probably contain only the basic part of the solver without detach conditions, as I have to build everything from scratch. I hope that I will find some time next weekend, but I can`t promise anything. when you say , (the same time you can search for closest drivers and get some part of their velocities) , do you mean point cloud approach ? Exactly, this approach is based entirely on pointclouds. Share this post Link to post Share on other sites
michaelb-01 15 Posted June 26, 2014 This looks great, I guess its similar to a FLIP method but using rbd objects instead of a grid? I'd love to see a hip file! Share this post Link to post Share on other sites
rayman 441 Posted June 30, 2014 This is the basic implementation of the sand upres solver. Keep in mind that you can implement much more features as initial offsets from target center so points will maintain their positions and wont merge together, dynamic detach of targets based on velocity changes, etc. This version won`t work well for fast moving base sim, as targets positions are taken based on distance from the points.

Thanks for sharing, really nice techniques! I'd like to see what will happen if combined this technique with flip simulation! Share this post Link to post Share on other sites

There was also a pass, quite heavy in terms of sim, of turbulent-swirling -ground level sand. A triky part I would pay attention to is the turbulence created at the edge of the dune wich is probably sucking in all the sand. I would use some air fields or collision modelling to control. There were lots of other artists that created this piece and lots of work was done to bring the final images. Each shot had its own challenges, it wasn't certainly a one-go solution. anyway, I would use real life references, not cg. hope this helps a bit! other users here at od force already told you all you need to know to get the desired effect, so not much to add really. Great work! Very inspiring indeed Share this post Link to post Share on other sites
