| MeshHandler (const osg::Geometry *pGfxGeometry) | |
| Builds a mesh handler from an existing geometry (do not copy data). | |
| MeshHandler (osg::Node *pModel) | |
| Convinience constructor that builds a mesh handler using a copy of the first geometry of the given node. | |
| MeshHandler (const osg::HeightField *pGfxHeightField) | |
| Builds a mesh handler by copying a height field into an internal geometry. | |

Detailed Description
GeometryHandler for meshes - Somewhat tested, quite stable, but still experimental.
- Version:
- 0.2.0 - Quite good but it seems to still have problems using trimeshes with ODE

Constructor & Destructor Documentation
| Physics::MeshHandler::MeshHandler | ( | const osg::Geometry * | pGfxGeometry | ) | [inline] |
Builds a mesh handler from an existing geometry (do not copy data).
Definition at line 392 of file GeometryHandlers.h.
| Physics::MeshHandler::MeshHandler | ( | osg::Node * | pModel | ) |
Convinience constructor that builds a mesh handler using a copy of the first geometry of the given node.
Dev note: Sorry but the Node * cannot be const since the constructor uses a visitor and OSG doesn't implement accept() for const nodes.
Definition at line 384 of file GeometryHandlers.cpp.
References meshDataId, pGeo, pOwnGeo, THROW_TRACED_EXCEPTION, and FindGeometriesVisitor::vFoundGeometries.
| Physics::MeshHandler::MeshHandler | ( | const osg::HeightField * | pGfxHeightField | ) |
Builds a mesh handler by copying a height field into an internal geometry.
- Deprecated:
- Use the HeightFieldHandler instead of the mesh handler for height field terrains.

| void Physics::MeshHandler::clearCache | ( | ) | [inline] |
Should be called each step (before world step) for trimesh collisions.

| dGeomID Physics::MeshHandler::create | ( | dSpaceID | spaceId | ) | [protected, virtual] |
- Todo:
- check if ALL primitive sets are triangles (list, strip, or fan) => use direct data. If not (Quads or mixed) => rebuild data or use no data.
- Todo:
- interpret BIND_PER_VERTEX by doing a sum + normalization (what about quads !? use 4-vertices or 3-vertices ?)
