Thanks very much for the explanation guys! These info are very useful...

Yes the objects are colliding many times each other... but it's only a performance test so in real situation this is not common. my space.SimulationSettings.CollisionResponse.Iterations is set to 8 and i've tried yet to enable multithreading , but the performance issue is still present. The only thi...

Hi Norbo, i've a strange problem with my engine. I create a simple scene with 15/20 convex hull entities (40/50 vertex each other) falling on the ground. All works great on windows, even if i increase the numer of object to 100/150. When i deploy the same code on Xbox, until each entity falls to sle...

This is the code to extract vertices: private List<Vector3> GetVerticesModel(float p_Scale) { List<Vector3> _points = new List<Vector3>(); foreach (ModelMesh modelMesh in m_XnaModel.Meshes) { foreach (ModelMeshPart part in modelMesh.MeshParts) { VertexPositionNormalTextureBinormalTangent[] _vertices...

Thanks very much, i solved my issue writing my own custom importer with a custom vertex!

Hi Norbo, i've just update to last 14.3 version and i started getting this error when i try to extract vertex data from an xna model: System.FormatException was unhandled Message=Unsupported vertex type in mesh. Source=BEPUphysics StackTrace: at BEPUphysics.DataStructures.TriangleMesh.AddMesh(ModelM...

Hi Norbo, this is the detail of the exception... System.NullReferenceException was unhandled Message="Riferimento a un oggetto non impostato su un'istanza di oggetto." Source="BEPUphysics" StackTrace: in BEPUphysics.Entities.Entity.applyForces(Single dt, Single timeScale) in BEPU...

Hi Norbo, i found an issue in some situation: when i call space.update() i get "Object not set on an instance of the object... try to use new keyword bla bla bla". This error doesn't appear after a specific action on physics, but sometimes appear... probabily in the update routines there's...

Hi all, i've this strange problem: I create a set of CompoundBody made by a simple ConvexHull object, and all of theese CompoundBody are identical each other. If i create them as dynamic object all works fine, but if i create all as nonDynamic objects, only the first added object to the space works ...

Ok thank you guys, i try with the compound body's specialized rayTest method.

Hi all, I've a question regarding (Space).rayCast... imagine to have 5 cube aligned along X axis (or Z or Y it doesn't matter!). They are part of one compoundbody. When i perform a ray cast, if the ray transfix all five cubes (or in another words, all the lenght of the compound body) i receive only ...

Yes great, now all works good!

Thanks!

Ok, now it seems to work well but there's an issue: when i aplly the final rotation matrix to make the L and the wall facing perfectly, by doing (entity).orientationMatrix * R1 * R2, this is applied at the geometric center (or at mass center i don't know) of the L object!!! But to have a right behav...

Ok, now the first part works very well, i'm able to align the face flatly to the wall. The right code should be this: Vector3 _up = controller.colliderA.orientationMatrix.Up; Vector3 _right = controller.colliderA.orientationMatrix.Right; Vector3 _forward = controller.colliderA.orientationMatrix.Forw...

Hi Norbo, i writed the code, the things seem to be in the right direction but it's still not works very well. Take a look at this two screens: This is without any correction, just a cube shooted toward the wall with its own collision angle: http://img9.imageshack.us/my.php?image=beforer.jpg This app...
