NAME
SoTextureCoordinate3 -The SoTextureCoordinate3 class contains a set of coordinates for the mapping of 2D textures.
When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack. Some shape nodes can then use these coordinates for explicit, detailed control of how 3D textures are mapped.
SYNOPSIS
#include <Inventor/nodes/SoTextureCoordinate3.h>
Inherits SoNode.

Detailed Description
The SoTextureCoordinate3 class contains a set of coordinates for the mapping of 2D textures.
When encountering nodes of this type during traversal, the coordinates it contains will be put on the state stack. Some shape nodes can then use these coordinates for explicit, detailed control of how 3D textures are mapped.
(If 3D textures are used without any SoTextureCoordinate3 nodes in the scenegraph leading up to a shape node, the shape types have default fallbacks. So SoTextureCoordinate3 nodes are only necessary to use if you are not satisfied with the default mapping.)
Note that an SoTextureCoordinate3 node will replace the coordinates already present in the state (if any).
Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Member Function Documentation
void SoTextureCoordinate3::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.
void SoTextureCoordinate3::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
References SoFieldContainer::get(), SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), and point.
Referenced by callback(), GLRender(), and pick().
void SoTextureCoordinate3::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(), SoFieldContainer::get(), SoNode::getNodeId(), SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), point, SoBase::staticDataLock(), and SoBase::staticDataUnlock().
void SoTextureCoordinate3::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 SoTextureCoordinate3::pick (SoPickAction * action) [virtual]Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
References doAction().
Member Data Documentation
SoMFVec3f SoTextureCoordinate3::pointThe set of 3D texture coordinates. Default value of field is an empty set.
Texture coordinates are usually specified in normalized coordinates, ie in the range [0, 1]. Coordinates outside the [0, 1] range can be used to repeat the texture across a surface.
