Detailed Description

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.

Member Function Documentation

◆ copy()

SoPickedPoint* SoPickedPoint::copy ( ) const

The caller is responsible for deleting the copy when done.

◆ getDetail()

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

If the node pointer is NULL (the default), the information corresponding to the tail of the path is returned. 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.

◆ getImageToObject()

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

◆ getMaterialIndex()

int SoPickedPoint::getMaterialIndex ( ) const

inline

Note that if the materials are interpolated between vertices, the index will correspond to the material at one of the vertices.

◆ isOnGeometry()

bool SoPickedPoint::isOnGeometry ( ) const

The pick style (see SoPickStyle) affects this decision.

Definition at line 125 of file SoPickedPoint.h.

◆ setDetail()

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

NULL may be passed to remove a detail. All detail pointers are NULL by default.

◆ setMaterialIndex()

void SoPickedPoint::setMaterialIndex ( int index )

inline

Definition at line 172 of file SoPickedPoint.h.

◆ setObjectNormal()

void SoPickedPoint::setObjectNormal ( const SbVec3f & normal )

Setting or changing the normal or texture coordinates at a later time may cause undefined results. Sets the normal in object space

◆ setObjectTextureCoords()

void SoPickedPoint::setObjectTextureCoords ( const SbVec4f & texCoords )
