When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack for later use by shape nodes of types which need coordinate sets (like **SoFaceSet** nodes or **SoPointSet** nodes). The fourth element of the coordinate vectors is used for normalization. A node of this type where all the normalization values are equal to 1.0 is the equivalent of setting up an **SoCoordinate3** node. Note that an **SoCoordinate4** node will *replace* the coordinates already present in the state (if any). **FILE FORMAT/DEFAULTS:** ``` Coordinate4 { point 0 0 0 1 } ``` **See also** **SoCoordinate3** ## Constructor & Destructor Documentation ### SoCoordinate4::SoCoordinate4 (void ) Constructor. ### SoCoordinate4::~SoCoordinate4 () \[protected\], \[virtual\] Destructor. ## Member Function Documentation ### SoType SoCoordinate4::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoCoordinate4::getTypeId (void ) const \[virtual\] Returns the type identification of an object derived from a class inheriting **SoBase**. This is used for runtime type checking and "downward" casting. Implements **SoBase**. ### const SoFieldData \*\* SoCoordinate4::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.*\ Returns the **SoFieldData** class which holds information about fields in this node. ### const SoFieldData \* SoCoordinate4::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 **SoFieldContainer**. ### void SoCoordinate4::doAction (SoAction \* action) \[virtual\] This function performs the typical operation of a node for any action. Reimplemented from **SoNode**. ### void SoCoordinate4::GLRender (SoGLRenderAction \* action) \[virtual\] Action method for the **SoGLRenderAction**. This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. Reimplemented from **SoNode**. ### void SoCoordinate4::getBoundingBox (SoGetBoundingBoxAction \* action) \[virtual\] Action method for the **SoGetBoundingBoxAction**. Calculates bounding box and center coordinates for node and modifies the values of the *action* to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node. Nodes influencing how geometry nodes calculate their bounding box also override this method to change the relevant state variables. Reimplemented from **SoNode**. ### void SoCoordinate4::callback (SoCallbackAction \* action) \[virtual\] Action method for **SoCallbackAction**. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the **SoCallbackAction** for extracting information about the scene graph. Reimplemented from **SoNode**. ### void SoCoordinate4::pick (SoPickAction \* action) \[virtual\] Action method for **SoPickAction**. Does common processing for **SoPickAction** *action* instances. Reimplemented from **SoNode**. ### void SoCoordinate4::getPrimitiveCount (SoGetPrimitiveCountAction \* action) \[virtual\] Action method for the **SoGetPrimitiveCountAction**. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the *action*. Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables. Reimplemented from **SoNode**. ## Member Data Documentation ### SoMFVec4f SoCoordinate4::point Coordinate set of 3D points as 4D vectors (each vector contains a 3D coordinate plus normalization value). ## Author Generated automatically by Doxygen for Coin from the source code.
