Detailed DescriptionThe SoTexture3 class is used to map a 3D texture onto geometry. Shape nodes within the scope of SoTexture3 nodes in the scenegraph (ie below the same SoSeparator and to the righthand side of the SoTexture3) will have the texture applied according to each shape type's individual characteristics. See the documentation of the various shape types (SoFaceSet, SoCube, SoSphere, etc etc) for information about the specifics of how the textures will be applied. An SoTexture3 node will override any previous encountered SoTexture2 nodes and vice versa. Mixing of SoTexture3 and SoTextureCoordinate2 (or the other way around) is legal, but the third texture coordinate component will be ignored (set to 0.0). 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 Enumeration Documentation
enum SoTexture3::ModelTexture mapping model. Enumerator MODULATE Texture image is modulated with polygon. DECAL Texture image overwrites polygon color. BLEND Blend image using blendColor.
enum SoTexture3::WrapEnum used to specify wrapping strategy. Enumerator REPEAT Repeat texture when coordinate is not between 0 and 1. CLAMP Clamp coordinate between 0 and 1.

Member Function Documentation
SoType SoTexture3::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting. Usage example: void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all 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 Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups. Implements SoBase.
const SoFieldData * SoTexture3::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 SoTexture3::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action. Reimplemented from SoNode.
void SoTexture3::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.
void SoTexture3::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.
SbBool SoTexture3::readInstance (SoInput * in, unsigned short flags) [protected], [virtual]This method is mainly intended for internal use during file import operations. It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type. TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE. flags is used internally during binary import when reading user extension nodes, group nodes or engines. Reimplemented from SoNode.
void SoTexture3::notify (SoNotList * l) [protected], [virtual]Notifies all auditors for this instance when changes are made. Reimplemented from SoNode.
int SoTexture3::getReadStatus (void) [protected]Returns read status. 1 for success, 0 for failure.
void SoTexture3::setReadStatus (int s) [protected]Sets read status. See also getReadStatus()
Member Data Documentation
SoMFString SoTexture3::filenamesTexture filename(s). Specify either this or use SoTexture3::images, not both. The depth of the volume is specifies by the number of filenames specified. All images must have the same dimensions and number of components. NB! A field sensor is attached to this field internally and reloads all images when this field changes. You must therefore be careful when setting this field and either use startEditing()/finishEditing() or set all values with one function call; setValues().
SoSFImage3 SoTexture3::imagesInline image data.
SoSFEnum SoTexture3::wrapRWrapping strategy for the R coordinate (depth).
SoSFEnum SoTexture3::wrapSWrapping strategy for the S coordinate.
SoSFEnum SoTexture3::wrapTWrapping strategy for the T coordinate.
SoSFEnum SoTexture3::modelTexture model.
SoSFColor SoTexture3::blendColorBlend color. Used when SoTexture3::model is SoTexture3::BLEND.
SoSFBool SoTexture3::enableCompressedTextureHint to Coin that compressed textures should be used if this is supported by the graphics hardware and OpenGL drivers. Using compressed textures usually reduces texture memory usage for a texture by 4-6 times. Since Coin 2.4.2 TGS Inventor 4.0
