Re: Guidelines for serializing btGImpactConvexDecompositionS

After jumping from a project to another... Here is the serialization patch. This patch includes : - updates for building on VS2005; - updates for building bullet with premake; - updates for serializing btGImpactCompoundShape; - updates for debugging btGImpactCompoundShape. I used the revision 2660 o...

Re: Is makesdna broken ?

I solved this by defining INTERNAL_UPDATE_SERIALIZATION_STRUCTURES.

Re: Guidelines for serializing btGImpactConvexDecompositionS

Thank you for pointing out the compilation trick about sBulletDNAstr64 and sBulletDNAstr. This isn't mentioned in the wiki.

In relation to your last statement, are you also implementing btGImpactConvexDecompositionShape serialization ?

Re: Is makesdna broken ?

Could an admin move my previous post here (Guidelines for serializing btGImpactConvexDecompositionShape) ?

Thanks

Is makesdna broken ?

Hello, I try to extend Bullet serialization. Before adding new stuffs, I want to regenerate the whole thing but makesdna seems broken. I use Visual Studio 2005 including service packs and I target x86 architecture. After the build process, btSerializer.cpp is uncomplete : diff --git a/src/LinearMath...

Re: triangle mesh with GImpact HOWTO

Luckily, I'm working with GImpact. However I don't use dynamics and maybe it will lacks some wiring. How to wire a collision object : btIndexedMesh indexedMesh = { ... // Fill this structure with the object mesh data }; btTriangleIndexVertexArray* indexedMeshes = new btTriangleIndexVertexArray(); in...

Guidelines for serializing btGImpactConvexDecompositionShape

Hello, I use GImpact stuffs for handling collision between a lot of moving meshes (no dynamics but an extensive use of contactTest). Testing Bullet, I have found btGImpactConvexDecompositionShape provides a huge performance boost over btGImpactMeshShape but building it is relatively slow. I think pr...

Collisions between btGImpactMeshShape instances

Hello, I'm trying to scale btGImpactMeshShape instances. A brief description of the application seems necessary. An user configures a display case by adding and moving several objects. The user moves just one selected object not a group of objects. The objects are scanned manually by the user (not a...
