NAME
SoCoordinate3 -The SoCoordinate3 class is a node for providing coordinates to shape nodes.
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 needs coordinate sets (like SoFaceSet nodes or SoPointSet nodes).
SYNOPSIS
#include <Inventor/nodes/SoCoordinate3.h>
Inherits SoNode.

Detailed Description
The SoCoordinate3 class is a node for providing coordinates to shape nodes.
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 needs coordinate sets (like SoFaceSet nodes or SoPointSet nodes).
Note that an SoCoordinate3 node will replace the coordinates already present in the state (if any).
FILE FORMAT/DEFAULTS:
Coordinate3 { point 0 0 0 }

Member Function Documentation
void SoCoordinate3::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoNode.
References SoNode::VRML1.
void SoCoordinate3::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
References SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), and point.
Referenced by callback(), getBoundingBox(), getPrimitiveCount(), GLRender(), and pick().
void SoCoordinate3::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.
References doAction(), SoNode::getNodeId(), SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), point, SoBase::staticDataLock(), and SoBase::staticDataUnlock().
void SoCoordinate3::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.
References doAction().
void SoCoordinate3::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 calculates their bounding box also overrides this method to change the relevant state variables.
Reimplemented from SoNode.
References doAction().
void SoCoordinate3::pick (SoPickAction * action) [virtual]Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
References doAction().
void SoCoordinate3::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 calculates their primitive count also overrides this method to change the relevant state variables.
Reimplemented from SoNode.
References doAction().
Member Data Documentation
SoMFVec3f SoCoordinate3::pointCoordinate set of 3D points.
Referenced by doAction(), GLRender(), SoTabPlaneDragger::reallyAdjustScaleTabSize(), and SoCoordinate3().
