An SoPickedPoint represents a point on the surface of an object that was picked by applying an SoRayPickAction to a scene. It contains a path to the picked shape, the point of intersection, the surface normal and texture coordinates at that point, and other information.
Each node in the picked path may have a corresponding instance of a detail subclass. These detail instances are stored in the SoPickedPoint.
SoPickedPoint(const SoPickedPoint
&pp)
Copy constructor.
~SoPickedPoint()
Destructor.
const SbVec3f & getPoint() const
const SbVec3f & getNormal() const
const SbVec4f & getTextureCoords() const
These return the intersection point and surface normal in world space, and the
texture coordinates in image space.
int getMaterialIndex() const
Returns the index into the current set of materials of the material active at
the intersection point. Note that if the materials are interpolated between
vertices, the index will correspond to the material at one of the
vertices.
SoPath * getPath() const
Returns the path to the object that was intersected.
SbBool isOnGeometry() const
Returns whether the intersection is actually on the geometry of the character
that was hit, as opposed to being on the bounding box. The pick style (see
SoPickStyle) affects this decision.
const SoDetail * getDetail(const SoNode *node = NULL)
const
Returns the detail that corresponds to the given node in the path returned by
getPath(). If the node pointer is NULL (the default), the detail
corresponding to the tail of the (full) path is returned.
const SbMatrix getObjectToWorld(const SoNode *node =
NULL) const
const SbMatrix getWorldToObject(const SoNode *node =
NULL) const
These return the transformation matrices between world space and the object
space corresponding to the given node in the path. If the node pointer is
NULL (the default), the matrix corresponding to the tail of the (full) path
is returned.
const SbMatrix getObjectToImage(const SoNode *node =
NULL) const
const SbMatrix getImageToObject(const SoNode *node =
NULL) const
These return the texture transformation matrices between image space and the
object space corresponding to the given node in the path. If the node
pointer is NULL (the default), the matrix corresponding to the tail of the
(full) path is returned.
const SbVec3f getObjectPoint(const SoNode *node =
NULL) const
const SbVec3f getObjectNormal(const SoNode *node =
NULL) const
const SbVec4f getObjectTextureCoords(const SoNode
*node=NULL) const
These return the intersection point, surface normal, and texture coordinates
in the object space corresponding to the given node in the path. If the node
pointer is NULL (the default), the information corresponding to the tail of
the (full) path is returned.
