Detailed DescriptionThe 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. See also SoRayPickAction
Constructor & Destructor Documentation
SoPickedPoint::SoPickedPoint (const SoPickedPoint & pp)Copy constructor.
SoPickedPoint::SoPickedPoint (const SoPath *const pathptr, SoState *const stateptr, 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 () constReturns a copy of this picked point. Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable are using the same instance of a C Run-Time (CRT) library. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes.
const SbVec3f & SoPickedPoint::getPoint () constReturns the world space point.
const SbVec3f & SoPickedPoint::getNormal (void) constReturns the world space normal.
const SbVec4f & SoPickedPoint::getTextureCoords () constReturns the image space texture coordinates.
int SoPickedPoint::getMaterialIndex () constReturns the material index.
SoPath * SoPickedPoint::getPath () constReturns the path to the picked object.
SbBool SoPickedPoint::isOnGeometry () constReturns 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) constReturns detail for node. If node equals NULL, the detail for the picked object is returned.
const SbMatrix & SoPickedPoint::getObjectToWorld (const SoNode *const node = NULL) constReturns 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) constReturns 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) constReturns 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) constReturns 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) constReturns the object space point, in the object space specified by node. If node equals NULL, the object space of the node where the point was actually picked will be used (this is what one would usually be interested in). node can be any node in the scenegraph.
SbVec3f SoPickedPoint::getObjectNormal (const SoNode *const node = NULL) constReturns 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) constReturns 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 & normalref)Sets the picked point objects space normal vector.
void SoPickedPoint::setObjectTextureCoords (const SbVec4f & texCoordsref)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.
