More complex collision objects

I want to make a cog as a collision object, I tried using a convex hull, but of course the space in between the teeth were covered by the collision geometry.

Am I right in thinking that the only way to accurately portray a cog using ogre newt is to define a compound collision geometry and manually define where each primitive is to form the overall shape?

Is there any automated compound collision geometry creator? Given the mesh?

you are right, that is the process. there is no automatic generation tool available, but I did release a "Rigid Body Designer" tool a while back that lets you define collision shapes visually, and saves the information to an XML file that can later be loaded with an included function...

it's floating around the forums somewhere...

[edit] here they are

cheers, i will take a look at these and let you know how i got on

i tried to compile the rigidbodyloader into a project i am working on, and it is having trouble compiling.

it seems the definitions for primative types is missing i got the following error

that loader was taken straight out of my StuntPlayground project, so you should remove the "namespace StuntPlayground" stuff from the source.

i removed all traces of the StuntPlayground namespace, and it still doesnt recognise any of the shapes, such as ELLIPSOID.

am i right in assuming that these are simple #defines of said names to ints to represent them ? (to make the case statements easier to read) ?

also, it doesnt appear to know what type PrimitiveType is

any information on how to define the shapes that this code needs, and how to define the PrimitiveType would be greatly appreciated

i read through the code and determined that PrimitiveType was probably an enumerated type, and added

enum PrimitiveType { BOX, ELLIPSOID, CYLINDER, CAPSULE, CONE, CHAMFER_CYLINDER, CONVEX_HULL, TREE };

to RigidBodyLoader.h

this alleviated all problems with PrimitiveType and shape types.

however, im having trouble getting TinyXML to link into the project, this probably isnt the place to ask about this, but i will ask anyway, given that you probably worked with tinyxml a bit.

I included, the tinyxml Release_STL and Debug_STR directories as linker directories (for release and debug builds respectivly), i included the tinxml directory as a code C/C++ source directory, and then did the PreProcessor define for TIXML_USE_STL, and also put the lib names in teh linking dependancies.

seems the tinyxml is included then linked, but alot of other linking errors appear

anyone got any idea what causes this ? have i missed something ?

i managed to get it to work, by recompiling the tinyxml_STL as multithreaded

cool! I will try and update the loader to work out of the box, by adding that enum...

i wrote a class to represent a rigid body loaded using the rigid body loader, however i was looking into scaling the rigidbody (along with its visual representitive), however, i couldnt find any methods on the OgreNewt::Body to scale it.

the only method that comes to mind (which is what i used for the other primitives) is to recreate the colision geometry and use OgreNewt::Body::setCollision.

any suggestions ?

you can also scale (convex) collision primitives by casting to OgreNewt::ConvexCollision (iirc) and then seting a generic scale matrix.

What license is the loader code, and the visual designer under?

the super-free-use-it-however-you-want license. seriously, there really is no license. use it however you want, make lots of money from it!

Sweet, thanks

NewtonPlayGround has an option to read 3ds max files. For instance, loading up "gear.3ds" seems to give us a non convex body.

Any insight into this? Is it doing something tricky?

it automatically makes a convex hull out of each sub-mesh (or whatever Max calls them) from the object into a single compound. so if you take care with the sub-mesh / sub-objects, it can auto-generate non-convex compounds.

ahhh i see. thanks for clearing that up

Hello Folks,

is the RigidBodyDesigner somewhere available? The walaber website is down.
Does somebody have the project to share?

Thanks in Advance!

Regards
Lax

cheers, i will take a look at these and let you know how i got on

Hope, I will
