Re: Error in compilation

This isn't really a Bullet build issue, but a dependencies problem. You're trying to link the SDL and SDL_image libraries, but they don't exist on your machine.
Find the library files for SDL and place them within your library directories and it should link correctly.

Re: Bullet Collision Callbacks?

Coincidence: I tried to access the same page earlier today, and ran into the same problem. I've found a backup here: http://web.archive.org/web/201207010451 ... d_Triggers

Re: Wrong collision with flat wall where have many lines [vi

Based on the video, it looks like the OP is trying to decipher the cause of the force that is applied to the car as it scrapes along the wall. More specifically, a force applied to the front-left of the car in the opposite direction of the car's velocity when the car slides past an edge in the wall'...

Re: Moving objects

You can use either, but it depends on the scenario. Would you like to synchronize your transforms across systems in your code? btRigidBody::setWorldTransform simply does exactly what you'd think it would do. btMotionState::setWorldTransform provides you the ability to override the transform's get/se...

Re: Simulating a flag using btSoftBody ?

Check out the demos that come with bullet- there are quite a few good examples within "SoftDemo.cpp" which show how to accomplish what you're trying to do. You'll need to figure out which node indices correspond to the vertices in the soft body which you'd like to constrain. Once you know ...

Re: Read files from sources

What's an IMG file? What's an MPQ file? Did you create them? Do they store graphics/physics data? This doesn't sound strictly bullet-related, as it seems like more of a file format/file system type of question. You'll want to load a file from disk into a data structure of your choosing, and then inj...

Re: Dynamica Manual Gone?

Google has a cache of the page: http://webcache.googleusercontent.com/s ... clnk&gl=us

I've noticed that a bunch of bullet-related pages are down now. Wonder what's up.

Re: Building just the libs

I just generated a solution for very similar build requirements. Here's a pretty thorough story of what I did: 1. Open CMakegui, and point to the source code and binary build directories. The source dir is the local svn repo, and the build is just some new folder the projects/solution will be dumped...

Re: bullet as a visibility engine

I view the Bullet engine components as a great way to perform the kinds of visibility testing that you've mentioned. If you dig into the library code, you'll see that the BulletDynamics project is built on top of what can be viewed as a totally separate component: BulletCollision. Since you're only ...

Re: Is there any method to export .bullet file from 3ds 2012

It doesn't look like there are any exporters currently maintained for 3ds max, unfortunately. Appears that you can, however, build the old PhysX bullet exporter yourself. Check this out: http://www.bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=12&t=8025 I'm stuck in the same situation, as I am...
