## Detailed Description

The **SoTextureCoordinate3** class contains a set of coordinates for the mapping of 2D textures.

When encountering a node 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 scene graph 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.\

## Constructor & Destructor Documentation

### SoTextureCoordinate3::SoTextureCoordinate3 (void )

Constructor.

### SoTextureCoordinate3::~SoTextureCoordinate3 () \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoTextureCoordinate3::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### SoType SoTextureCoordinate3::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 \*\* SoTextureCoordinate3::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 \* SoTextureCoordinate3::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 SoTextureCoordinate3::doAction (SoAction \* action) \[virtual\]

This function performs the typical operation of a node for any action.

Reimplemented from **SoNode**.

### 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 want to throw geometry primitives at OpenGL override this method.

Reimplemented from **SoNode**.

### 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**.

### void SoTextureCoordinate3::pick (SoPickAction \* action) \[virtual\]

Action method for **SoPickAction**.

Does common processing for **SoPickAction** *action* instances.

Reimplemented from **SoNode**.

## Member Data Documentation

### SoMFVec3f SoTextureCoordinate3::point

The set of 3D texture coordinates. Default value of field is an empty set.

Texture coordinates are usually specified in normalized coordinates, i.e. in the range \[0, 1\]. Coordinates outside the \[0, 1\] range can be used to repeat the texture across a surface.
