Constructor & Destructor Documentation

Appearance (  const NodeType &    nodeType, const ScopePtr &    scope )

Constructor. Parameters: nodeType  the NodeType associated with the node instance. scope  the Scope to which the node belongs.

~Appearance (    )  throw () [virtual]

Destructor.

Member Function Documentation

const SFNode & getMaterial (    )  const throw () [virtual]

Get the material node. Returns: an SFNode object containing the Material node associated with this Appearance. Implements AppearanceNode.

const SFNode & getTexture (    )  const throw () [virtual]

Get the texture node. Returns: an SFNode object containing the texture node associated with this Appearance. Implements AppearanceNode.

const SFNode & getTextureTransform (    )  const throw () [virtual]

Get the texture transform node. Returns: an SFNode object containing the TextureTransform node associated with this Appearance. Implements AppearanceNode.

bool isModified (    )  const [virtual]

Determine whether the node has been modified. Returns: true if the node or one of its children has been modified, false otherwise. Reimplemented from Node.

void processSet_material (  const FieldValue &    sfnode, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_material eventIn handler. Parameters: sfnode  an SFNode value; should be a Material node. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

void processSet_texture (  const FieldValue &    sfnode, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_texture eventIn handler. Parameters: sfnode  an SFNode value; should be a Texture node. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

void processSet_textureTransform (  const FieldValue &    sfnode, double    timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

set_textureTransform eventIn handler. Parameters: sfnode  an SFNode value; should be a TextureTransform node. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

void render (  Viewer &    viewer, VrmlRenderContext    context )  [virtual]

Render the node. Parameters: viewer  a Viewer. context  a rendering context. Reimplemented from Node.

void updateModified (  NodePath &    path, int    flags = 0x003 )  [virtual]

Propagate the bvolume dirty flag from children to parents. Parameters: path  stack of ancestor nodes. flags  1 indicates normal modified flag, 2 indicates the bvolume dirty flag, 3 indicates both. Reimplemented from Node.
