Detailed Description

The SoDetail class is the superclass for all classes storing detailed information about particular shapes.

Detail information about shapes is used in relation to picking actions in Coin. They typically contain the relevant information about what particular part of the shape a pick ray intersected with.

SoDetail::~SoDetail (  )  [virtual]

Default constructor.

Member Function Documentation

void SoDetail::initClass (  void )  [static]

Initialize relevant common data for all instances, like the type system. Reimplemented in SoConeDetail, SoCubeDetail, SoCylinderDetail, SoFaceDetail, SoLineDetail, SoNodeKitDetail, SoPointDetail, and SoTextDetail.

void SoDetail::initClasses (  void )  [static]

Call the initClass() methods of all built-in detail classes. (The initClass() method of user extension detail classes -- if any -- must be called explicitly by the application programmer in the application initialization code.)

SoDetail * SoDetail::copy (  void )  const [pure virtual]

Return a deep copy of ourself. Reimplemented in SoConeDetail, SoCubeDetail, SoCylinderDetail, SoFaceDetail, SoLineDetail, SoNodeKitDetail, SoPointDetail, and SoTextDetail.

SoType SoDetail::getTypeId (  void )  const [pure virtual]

Returns the type identification of a detail derived from a class inheriting SoDetail. This is used for run-time type checking and "downward" casting. Usage example: void fuhbear(SoDetail * detail) { if (detail->getTypeId() == SoFaceDetail::getClassTypeId()) { // safe downward cast, know the type SoFaceDetail * facedetail = (SoFaceDetail *)detail; } return; // ignore if not a SoFaceDetail } For application programmers wanting to extend the library with new detail classes: this method needs to be overloaded in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through Inventor/nodes/SoSubDetail.h: SO_DETAIL_SOURCE and SO_DETAIL_INIT_CLASS.

SbBool SoDetail::isOfType (  const SoType type )  const

Returns TRUE if type is derived from (or is) this class.

SoType SoDetail::getClassTypeId (  void )  [static]

Returns the type for this class.
