Constructor & Destructor Documentation

openvrml::vrml97_node::appearance_node::appearance_node (  const node_type &  type, const scope_ptr &  scope )

Construct. Parameters: type  the node_type associated with the node instance. scope  the scope to which the node belongs. Reimplemented from openvrml::appearance_node.

Member Function Documentation

const node_ptr & openvrml::vrml97_node::appearance_node::material (   )  const throw () [virtual]

Get the material node. Returns: an sfnode object containing the Material node associated with this Appearance. Implements openvrml::appearance_node.

bool openvrml::vrml97_node::appearance_node::modified (   )  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 openvrml::node.

void openvrml::vrml97_node::appearance_node::process_set_material (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

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

void openvrml::vrml97_node::appearance_node::process_set_texture (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

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

void openvrml::vrml97_node::appearance_node::process_set_textureTransform (  const field_value &  value, double  timestamp )  throw (std::bad_cast, std::bad_alloc) [private]

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

void openvrml::vrml97_node::appearance_node::render (  openvrml::viewer &  viewer, rendering_context  context )  [virtual]

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

const node_ptr & openvrml::vrml97_node::appearance_node::texture (   )  const throw () [virtual]

Get the texture node. Returns: an sfnode object containing the texture node associated with this Appearance. Implements openvrml::appearance_node.

const node_ptr & openvrml::vrml97_node::appearance_node::texture_transform (   )  const throw () [virtual]

Get the texture transform node. Returns: an sfnode object containing the TextureTransform node associated with this Appearance. Implements openvrml::appearance_node.
