Destructor.Member Function Documentation¶
SoType SoPointLight::getTypeId (void) const [virtual]¶
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting. Usage example:void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } }For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden 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 for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups. Reimplemented from SoLight. Reimplemented in SoPointLightManip.
const SoFieldData ** SoPointLight::getFieldDataPtr (void) [static], [protected]¶
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Reimplemented from SoLight. Reimplemented in SoPointLightManip.const SoFieldData * SoPointLight::getFieldData (void) const [protected], [virtual]¶
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. Reimplemented from SoLight. Reimplemented in SoPointLightManip.void SoPointLight::GLRender (SoGLRenderAction *action) [virtual]¶
Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoNode. Reimplemented in SoPointLightManip.Member Data Documentation¶
SoSFVec3f SoPointLight::location¶
3D position of lightsource. Default value is <0, 0, 1>.Author¶
