When rendering (or applying other actions), Coin will add a transformation which transforms the geometry into the \fBSoGeoOrigin\fP coordinate system\&. All objects will be rotated to make the local Z axis point up from the ground (at the specified geo-location), the Y axis will point towards the north pole, and the X axis is found using the right hand rule\&. .PP \fBSee also:\fP .RS 4 \fBSoGeoOrigin\fP .RE .PP \fBSince:\fP .RS 4 Coin 2\&.5 .RE .PP .SH "Constructor & Destructor Documentation" .PP .SS "SoGeoSeparator::SoGeoSeparator (void)" Constructor\&. .SS "SoGeoSeparator::~SoGeoSeparator (void)\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoGeoSeparator::getTypeId (void) const\fC [virtual]\fP" .PP Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example: .PP .PP .nf void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } } .fi .PP .PP For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP 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 \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&. .PP For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "const \fBSoFieldData\fP * SoGeoSeparator::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP" Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::callback (\fBSoCallbackAction\fP *action)\fC [virtual]\fP" Action method for \fBSoCallbackAction\fP\&. .PP Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::GLRenderBelowPath (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP" SGI Open Inventor v2\&.1 obsoleted support for \fBSoGLRenderAction::addMethod()\fP\&. Instead, \fBGLRender()\fP might be called directly, and to optimize traversal, the \fBSoSeparator\fP node calls GLRenderBelowPath whenever the path code is BELOW_PATH or NO_PATH (path code is guaranteed not to change)\&. To be compatible with SGI's Inventor (and thereby also TGS') we have chosen to follow their implementation in this respect\&. .PP \fBSoSeparator::GLRenderBelowPath()\fP do not traverse its children using \fBSoChildList::traverse()\fP, but calls \fBGLRenderBelowPath()\fP directly for all its children\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::GLRenderInPath (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP" Implements the SoAction::IN_PATH traversal method for the rendering action\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::getBoundingBox (\fBSoGetBoundingBoxAction\fP *action)\fC [virtual]\fP" Action method for the \fBSoGetBoundingBoxAction\fP\&. .PP Calculates bounding box and center coordinates for node and modifies the values of the \fIaction\fP to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node\&. .PP Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::getMatrix (\fBSoGetMatrixAction\fP *action)\fC [virtual]\fP" Action method for \fBSoGetMatrixAction\fP\&. .PP Updates \fIaction\fP by accumulating with the transformation matrix of this node (if any)\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::rayPick (\fBSoRayPickAction\fP *action)\fC [virtual]\fP" Action method for \fBSoRayPickAction\fP\&. .PP Checks the ray specification of the \fIaction\fP and tests for intersection with the data of the node\&. .PP Nodes influencing relevant state variables for how picking is done also overrides this method\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SS "void SoGeoSeparator::getPrimitiveCount (\fBSoGetPrimitiveCountAction\fP *action)\fC [virtual]\fP" Action method for the \fBSoGetPrimitiveCountAction\fP\&. .PP Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the \fIaction\fP\&. .PP Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables\&. .PP Reimplemented from \fBSoSeparator\fP\&. .SH "Member Data Documentation" .PP .SS "\fBSoSFVec3d\fP SoGeoSeparator::geoCoords" Used for specifying the geographic coordinates\&. .PP \fBSee also:\fP .RS 4 \fBSoGeoOrigin::geoCoords\fP .RE .PP .SS "\fBSoMFString\fP SoGeoSeparator::geoSystem" Used to specify a spatial reference frame\&. .PP \fBSee also:\fP .RS 4 \fBSoGeoOrigin::geoSystem\fP .RE .PP .SH "Author" .PP Generated automatically by Doxygen for Coin from the source code\&.
