NAME
SoTextureCubeMap -
The SoTextureCubeMap class is used to map a cube map onto subsequent shape nodes.
Shape nodes within the scope of SoTextureCubeMap nodes in the scenegraph (ie below the
same SoSeparator and to the righthand side of the SoTextureCubeMap) 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.

Detailed Description
The SoTextureCubeMap class is used to map a cube map onto subsequent shape nodes.
Shape nodes within the scope of SoTextureCubeMap nodes in the scenegraph (ie below the
same SoSeparator and to the righthand side of the SoTextureCubeMap) 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.

Member Enumeration Documentation
enum SoTextureCubeMap::Model
Texture mapping model, for deciding how to 'merge' the texturemap with the object it is
mapped onto.
Enumerator
MODULATE
Texture color is multiplied by the polygon color. The result will be Phong shaded
(if light model is PHONG).
DECAL Texture image overwrites polygon shading. Textured pixels will not be Phong shaded.
Has undefined behaviour for grayscale and grayscale-alpha textures.
BLEND This model is normally used with monochrome textures (i.e. textures with one or two
components). The first component, the intensity, is then used to blend between the
shaded color of the polygon and the SoTextureCubeMap::blendColor.
REPLACE
Texture image overwrites polygon shading. Textured pixels will not be Phong shaded.
Supports grayscale and grayscale alpha textures. This feature requires OpenGL 1.1.
MODULATE will be used if OpenGL version < 1.1 is detected.
Please note that using this texture model will make your Inventor files incompatible with
older versions of Coin and Inventor. You need Coin >= 2.2 or TGS Inventor 4.0 to load
Inventor files that uses the REPLACE texture model.
enum SoTextureCubeMap::Wrap
Enumeration of wrapping strategies which can be used when the texturemap doesn't cover the
full extent of the geometry.
Enumerator
REPEAT Repeat texture when coordinate is not between 0 and 1.
CLAMP Clamp coordinate between 0 and 1.
Constructor & Destructor Documentation
SoTextureCubeMap::SoTextureCubeMap (void)
Constructor.
SoTextureCubeMap::~SoTextureCubeMap () [protected], [virtual]
Destructor. Frees up internal resources used to store texture image data.
Member Function Documentation
SoType SoTextureCubeMap::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 * SoTextureCubeMap::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 SoTextureCubeMap::doAction (SoAction *action) [virtual]
This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
void SoTextureCubeMap::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 SoTextureCubeMap::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 SoTextureCubeMap::rayPick (SoRayPickAction *action) [virtual]
Action method for SoRayPickAction.
Checks the ray specification of the action and tests for intersection with the data of the
node.
Nodes influencing relevant state variables for how picking is done also overrides this
method.
Reimplemented from SoNode.
SbBool SoTextureCubeMap::readImage (const SbString &fname, int &w, int &h, int &nc, unsigned
char *&bytes) [static]
Not implemented in Coin; should probably not have been public in the original SGI Open
Inventor API. We'll consider to implement it if requested.
SbBool SoTextureCubeMap::readInstance (SoInput *in, unsigned shortflags) [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 SoTextureCubeMap::notify (SoNotList *l) [protected], [virtual]
Notifies all auditors for this instance when changes are made.
Reimplemented from SoNode.
int SoTextureCubeMap::getReadStatus (void) [protected]
Returns read status. 1 for success, 0 for failure.
void SoTextureCubeMap::setReadStatus (ints) [protected]
Sets read status.
