Member Function Documentation

Viewer::Object insertGeometry (  Viewer &    viewer, VrmlRenderContext    context )  [virtual]

Insert this geometry into viewer's display list. Parameters: viewer  a Viewer. context  the rendering context. Implements GeometryNode.

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

set_color eventIn handler. Parameters: sfnode  an SFNode value. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

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

set_height eventIn handler. Parameters: mffloat  an MFFloat value. timestamp  the current time. Exceptions: std::bad_cast  if mffloat is not an MFFloat. std::bad_alloc  if memory allocation fails.

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

set_normal eventIn handler. Parameters: sfnode  an SFNode value. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

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

set_texCoord eventIn handler. Parameters: sfnode  an SFNode value. timestamp  the current time. Exceptions: std::bad_cast  if sfnode is not an SFNode. std::bad_alloc  if memory allocation fails.

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.
