Detailed Description

Interface class for primitives represented in the physical and graphical world.

This is intended to bring OSG and ODE together and hide most implementation details.

Member Enumeration Documentation

enum Category

Enumeration values: Dyn  Stat

enum Modes

Body means that it is a dynamic object with a body. Geom means it has a geometrical represenation used for collision detection. Draw means the primitive is drawn Child is only used internally and is used for transformed geoms. Enumeration values: Body  Geom  Draw  Child

Member Function Documentation

void attachGeomAndSetColliderFlags (   )  [protected, virtual]

attaches geom to body (if any) and sets the category bits and collision bitfields. assumes: mode & Geom != 0

dBodyID getBody (   )  const

returns ODE bodyID if there

dGeomID getGeom (   )  const

returns ODE geomID if there

virtual OSGPrimitive* getOSGPrimitive (   )  [pure virtual]

returns the assoziated osg primitive if there or 0 Implemented in HeightField, InvisibleBox, InvisibleSphere, InvisibleCapsule, Plane, Box, Sphere, Capsule, Cylinder, Mesh, Transform, and DummyPrimitive.

osg::Matrix getPose (   )  const

returns the pose

osg::Vec3 getPosition (   )  const

returns the position

virtual void init (  const OdeHandle &  odeHandle, double  mass, const OsgHandle &  osgHandle, char  mode = Body|Geom|Draw )  [pure virtual]

registers primitive in ODE and OSG. Parameters: osgHandle  scruct with ODE variables inside (to specify space, world...) mass  Mass of the object in ODE (if withBody = true) osgHandle  scruct with OSG variables inside (scene node, color ...) mode  is a conjuction of Modes. Implemented in HeightField, InvisibleBox, InvisibleSphere, InvisibleCapsule, Plane, Box, Sphere, Capsule, Cylinder, Mesh, Transform, and DummyPrimitive.

void setPose (  const osg::Matrix &  pose  )

set the pose of the primitive Reimplemented in HeightField.

void setPosition (  const osg::Vec3 &  pos  )

set the position of the primitive (orientation is preserved)

void setTexture (  const std::string &  filename, bool  repeatOnX, bool  repeatOnY )  [virtual]

assigns a texture to the primitive, you can choose if the texture should be repeated

void setTexture (  const std::string &  filename  )  [virtual]

assigns a texture to the primitive

virtual void update (   )  [pure virtual]

Updates the OSG nodes with ODE coordinates. This function must be overloaded (usually calls setMatrix of OsgPrimitives) Implemented in HeightField, InvisibleBox, InvisibleSphere, InvisibleCapsule, Plane, Box, Sphere, Capsule, Cylinder, Mesh, Transform, and DummyPrimitive.
