Thanks a'lot, i will dive into docs.

Bullet Update:

I implemented static animated geometry.

Its using for pushing objects - for eg. Earthquake = Road cracks going up and then down

I want to apologize to SESI, When I said that there is the plugin for voronoi fracture, so I dont understand why H11 includes this asset —>>> I tested it and new voronoi is very fast and accurate then original plugin!!!

I compiled source code for H11, so I think that H11 catch me :shock:

I'm trying to optimize the process of loading objects and try to implements convex decomposition using multiple-threads. But no result.

When I write # include <pthread.h>, compiler says “file not found”.

I use VS2005 on 64bit Win7

Did someone similar problem???

Not sure exactly, as I use Linux/OS X myself. However, it might be that pthread.h isn't in your environment variables path, so the compiler isn't finding it.

Isn't pthread mainly a linux library? I know I had trouble with it when I was looking at it for windows.

Think you might have to compile it yourself.

If this is a Houdini plugin, you might try the multi-threading support built into the HDK, which should work on any platform Houdini runs on.

thx all

After hour I thought that pthread is for linux too. But I find some my old source code where I use multi-thread and for window its thread.h - but compiler write same error

So I will try HDK Thread from Johner links.

In this moment I simulate very big scene with fast response and low memory, but I must waiting over sending data from houdini to bullet(first frame), than Everything is fast(to the size of the scene)

I have problems with Convex decomposition.

If I have two and more complicated concave objects close together I have problem with Convex decom which create a little bit different shape and bullet very fast push away this intersect objects.

So I decided write my own convex decomposition or there is any open source project with solved this problems????

Solved … Smooooth …

Nothing special, no constraints, few bodies and In viewport you can see geometry for bullet collision. I will write code for applying transform data on original geometry, in this moment is not important :wink:

The reason for this test is new decomp system and its much more faster and I dont find any geometry “compression” so bullet return nice result (no explosions )


Ouu and finaly I jump to the H11, but within voronoi I havent tested another tool yet :?

awesome!

WIP pics

Frist floor with a lot of constraints.

This is still work in progress so some constraints still missing( for eg. roof with wall ) and boards on the floor is long(from one wall to other wall), but its fracture by voronoi.

Next problem its that I must test house with more max_forces(constraints) parameters because If I set big value, house dont break up, but with low value he break like a house of cards :?


I create HDK plugin for generating constraints and for example all board(the bigest geo in scene) compute in 1-2second, so its fast. :shock:

third WIP video: http://vimeo.com/14346567 [vimeo.com]

just more details and better house structure. With bullet plugin nothing changed :-). So version 1.0 is more and more closer.

There is still few bugs with setting max_forces(constraints), Its really difficult finding where every material have maximum force before breaking.

The most amazing thing is that if I hit play and I have all ground, The house dont breaks, so the all constraints working great and structure is right.


Objects: 2525
Constraints: 11731 :shock:
Time per frame: about 5s (substep: 10)
Cache files: 1.4GB(Bgeo)

Hell yees, 11731 constraints and its stable :!:

Great progres man, realy interesting dynamics…

I wolud realy like to see yout test on some building, huge,

i made some fast test just for idea..

CeeGee
i made some fast test just for idea..

Great test, CeeGee. Did you use H11 integrated voronoï or bullet+voronoï from odForce ?

How much time for simulation ?

CeeGee: nice test, before few months I working on this “type” of building with bullet DOP and I had similar result. Its want some constraints ( a lot of constraints :twisted: )

But problem is that I study and I must work on my bachelor work: http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=20518&start=0&postdays=0&postorder=asc&highlight= [sidefx.com]

I still working on bullet implementation, but in this moment My priority are in the muscle and skin toolkit.

I still waiting on Bullet 3.x.x with GPU fluids and OpenCL support. In this moment the plugin is not done I dont want to publish it for testing because It will have a lot of work with fixing your sending bugs and I must do some school stuff, so I dont have time for this. The next thing is documentation for bullet which I have to write for you :cry:

ok, I make some progress.

I have few days free time. So I created example file with basic settings of plugin and now I finishing documentation so within few days waiting for first release of plugin.

I am sure that plugin will be compilated for win64, some days later win32.

Problem is that I dont have any experience with compiling under linux. I check that apprentice is for many Unix systems, so Have I compile for all this system??? And what about 32bit vs 64bit???


And I am sure that MacOS will not be supported because I dont have this OS in my HDD and I dont know anybody who has Mac. Sorry.

Yeh, compiling for linux requires specific versions of gcc depending on what version of Houdini you use.

I have a mac. I'm not a specialist of compilation, but i can try if you want.
