MilanSuk Posted November 7, 2013 Share Posted November 7, 2013 (edited) BulletSOP is implementation of Bullet library (bulletphysics.org) inside SideFx Houdini (sidefx.com). It's a plugin for creating incredibly large rigid body simulations on average PC. The Tool is very powerful, flexible and speed is very impressive as well as memory footprint.The plugin is free and without limits! So you can create truly stunning massive simulations. BulletSOP is compiled for Houdini production builds. It includes many example scenes (beginner -> professional) which are probably the best learning resources. Main features: - Bullet RBD Solver - Support for multiple Broadphases, Constraints Solvers - Loading data from previous frame - Geometry decomposition (Tetrahedra, Voxels) - Static/Animation body - Convex Hull - Compound Hull - Deform static Hull - Primitive Hulls - Constraints (auto-generating, spring, 6DoF) - Collisions Groups - Object Forces - Point Radius Forces - Delete Duplicity data - Instancing - Emitting system - Includes many example scenes for studying - Support for Windows(64bit) and Linux(64bit) - Support for Houdini 12 & 13 Links: Houdini: http://www.sidefx.com/ LinkedIn: http://www.linkedin....Houdini-4796605 More author's videos: https://vimeo.com/user3251535 Create freely, simulate quickly and enjoy fully!

MilanSuk Posted November 7, 2013 Author Share Posted November 7, 2013 (edited) For this release We added support for Houdini13, documetation(WIP) and icons - big thank you to Igor Bondar. There is new MLCPSolver and few significant bug fixes(when you hit "ESC" key for interuption and Houdini won't update graph, ....) and a lot of minor bug fixes and speed and layout improvements! I also added House Destruction scene: https://vimeo.com/77407481 Edited November 7, 2013 by MilanSuk 1 Quote Link to comment Share on other sites More sharing options...

aeroba Posted November 10, 2013 Share Posted November 10, 2013 (edited) Hi Milan! I had try to use bullet sop with constraint like your house destruction and have some problem. When i add Calculate mass or add less constraint max force to sim my since always crash. I'don't know why. My Houdini always crash. This is my since. please help me. wood fracture crash.hip Edited November 10, 2013 by aeroba Quote Link to comment Share on other sites More sharing options...
MilanSuk Posted November 10, 2013 Author Share Posted November 10, 2013 (edited) I'don't know why. My Houdini always crash. This is my since. please help me. I checked log and looks like a bug in BulletLibrary. You also made one mistake - It's not recommend to use grid shape(It's not closed object) like a floor object. You must use box or turn_on floor on btSolver node. Please check attachment. It works! wood fracture crash.hip Edited November 11, 2013 by MilanSuk Quote Link to comment Share on other sites More sharing options...
Andre62 Posted November 11, 2013 Share Posted November 11, 2013 (edited) Hello, how can i use custom velocity forces in bulletsop? Edited November 11, 2013 by Andre62 Quote Link to comment Share on other sites More sharing options...
MilanSuk Posted November 11, 2013 Author Share Posted November 11, 2013 (edited) Hello, how can i use custom velocity forces in bulletsop? If you want to apply force(s) on object(s). Look into example file to scenes "basic/forces_swirl" or "basic/forces_magnets" Edited November 11, 2013 by MilanSuk Quote Link to comment Share on other sites More sharing options...

jackyu00 Posted November 20, 2013 Share Posted November 20, 2013 Hi Milan Thanks for the great RBD solution. The speed of simulation is amazing! Much faster than Bullet DOP, also the constraint is very handy to use. I am checking the example file "voroni_impact_break", and I have some questions about btLoader. In the doc it said "btLoader Loads data from previous frame from the specified btSolver" Since we can specity solver path in the node, what is the input plug of btLoader for? What will happen if we plug something to the input of btLoader? Jack Quote Link to comment Share on other sites More sharing options...

And after Reset Frame it ignores input and load data from btSolver! Quote Link to comment Share on other sites More sharing options...

prashantcgi Posted December 6, 2013 Share Posted December 6, 2013 HI Milan Thanks for the awesome plugin I recently bought iMac i want to use your plugin on OSX If possible can you please release it for mac also Kind regards Quote Link to comment Share on other sites More sharing options...
MilanSuk Posted December 9, 2013 Author Share Posted December 9, 2013 If possible can you please release it for mac also We've worked on it already! But there are some problems with compiler settings. So If somebody want to help, please send me email. Quote Link to comment Share on other sites More sharing options...
sliver Posted December 19, 2013 Share Posted December 19, 2013 (edited) SOLVED sorry Hello Milan, I'm working on bulletsop for my personal curiosity and I'm stuck, because it seems to have a little bug. I have a ground (grid + moutain sop) when I set my bt_build to deform it doesn't work (simulation doesn't run), and when I choose box by example, the simulation works, but collision are not perfect like deform. What do you think about it ? (BulletSop 2.0.10 on H 13.0.198.21) Thank you very much for your help and your plug in. gold_coins_sim_003_bug.hip Edited December 20, 2013 by sliver Quote Link to comment Share on other sites More sharing options...

But If somebody want's to know what was wrong: You don't connect 2nd input(Shapes) on btSolver 1 Quote Link to comment Share on other sites More sharing options...
