Detailed Description

The SoPickedPoint class is used for specifying picked points.

It holds miscellaneous information about the picked point, such as position, normal, texture coordinate and material index in the current material. It might also hold detail information (an SoDetail subclass) for every node in the picked path.

Constructor & Destructor Documentation

SoPickedPoint::SoPickedPoint (  const SoPickedPoint & pp )

Copy constructor.

SoPickedPoint::SoPickedPoint (  const SoPath *const path, SoState *const state, const SbVec3f & objSpacePoint )

Constructor. Uses the state to convert between world and object space for the data.

SoPickedPoint::~SoPickedPoint (  )

Destructor.

Member Function Documentation

SoPickedPoint * SoPickedPoint::copy (  void )  const

Returns a copy of this picked point.

const SbVec3f & SoPickedPoint::getPoint (  )  const

Returns the world space point.

const SbVec3f & SoPickedPoint::getNormal (  void )  const

Returns the world space normal.

const SbVec4f & SoPickedPoint::getTextureCoords (  )  const

Returns the image space texture coordinates.

int SoPickedPoint::getMaterialIndex (  )  const

Returns the material index.

SoPath * SoPickedPoint::getPath (  void )  const

Returns the path to the picked object.

SbBool SoPickedPoint::isOnGeometry (  )  const

Returns TRUE if this picked point is on the actual geometry of the picked object, or FALSE if not (it might for instance be on the bounding box if picking was done on bounding boxes).

const SoDetail * SoPickedPoint::getDetail (  const SoNode *const node = NULL )  const

Returns detail for node. If node equals NULL, the detail for the picked object is returned.

const SbMatrix & SoPickedPoint::getObjectToWorld (  const SoNode *const node = NULL )  const

Returns the matrix which converts from object (specified by node) to world space. If node equals NULL, the object space of the picked object will used.

const SbMatrix & SoPickedPoint::getWorldToObject (  const SoNode *const node = NULL )  const

Returns the matrix which converts from world to object (specified by node) space. If node equals NULL, the object space of the picked object will used.

const SbMatrix & SoPickedPoint::getObjectToImage (  const SoNode *const node = NULL )  const

Returns the matrix which converts from object (specified by node) to image space. If node equals NULL, the object space of the picked object will used.

const SbMatrix & SoPickedPoint::getImageToObject (  const SoNode *const node = NULL )  const

Returns the matrix which converts from image to object (specified by node) space. If node equals NULL, the object space of the picked object will used.

SbVec3f SoPickedPoint::getObjectPoint (  const SoNode *const node = NULL )  const

Returns the object space (specified by node) point. If node equals NULL, the picked point object space will be used.

SbVec3f SoPickedPoint::getObjectNormal (  const SoNode *const node = NULL )  const

Returns the object space (specified by node) normal. If node equals NULL, the picked point object space will be used.

SbVec4f SoPickedPoint::getObjectTextureCoords (  const SoNode *const node = NULL )  const

Returns the object space (specified by node) texture coordinates. If node equals NULL, the picked point object space will be used.

void SoPickedPoint::setObjectNormal (  const SbVec3f & normal )

Sets the picked point objects space normal vector.

void SoPickedPoint::setObjectTextureCoords (  const SbVec4f & texCoords )

Sets the picked point object space texture coordinates.

void SoPickedPoint::setMaterialIndex (  const int index )

Sets the material index.

void SoPickedPoint::setDetail (  SoDetail * detail, SoNode * node )

Sets the detail for node. node must be in the picked path, of course. Set to NULL if you want to remove a detail for a node.
