Public Attributes | |
Exposed Fields | |
A field that is capable of receiving events via an eventIn to change its value(s), and generating events via an eventOut when its value(s) change. | |
MFNode | children |
SFFloat | tessellationScale |
Fields | |
A property or attribute of a node. Each node type has a fixed set of fields. Fields may contain various kinds of data and one or many values. Each field has a default value. | |
SFVec3f | bboxCenter |
SFVec3f | bboxSize |
Events In | |
EventIn< MFNode > | addChildren |
EventIn< MFNode > | removeChildren |

The NurbsGroup node groups a set of NurbsSurface nodes to a common group. This provides a hint to the browser to treat the set of NurbsSurface nodes appearing in a Shape node in children as a unit during tessellation to enforce tessellation continuity along borders. The tessellationScale parameter scales the tessellation values in lower-level NurbsCurve and NurbsSurface nodes. If a set of NurbsSurfaces uses a matching set of control points along the borders, this results in a common tessellation stepping.
NurbsGroup | ( | const char * | name = "" |
) |
Construct a node with all its fields set to default value, which is equivalent to the code below:
tessellationScale = 1.0f; bboxCenter.setXYZ(0,0,0); bboxSize.setXYZ(-1,-1,-1);
~NurbsGroup | ( | ) | [virtual] |
Virtual destructor, does nothing
unsigned int nbFields | ( | ) | const [inline, virtual] |
Returns the number of fields (exposed or not) for this node type.
Implements Node.
wrl::Node::FieldHandle field | ( | const std::string & | n | ) | [virtual] |
Return a handle on the field named n
of the node or a "unknown" typed handle if there is no such field. Valid names are:
Implements Node.
wrl::Node::FieldHandle field | ( | unsigned int | n | ) | [virtual] |
Return a handle on the i
th field of the node or a "unknown" typed handle if there is no such node. Here is how i
is related to fields:
Implements Node.
bool isSetToDefaultValue | ( | unsigned int | i | ) | const [virtual] |
Implements Node.
unsigned int nbEventsIn | ( | ) | const [inline, virtual] |
Returns the number of events in for this node type.
Implements Node.
wrl::Node::EventInHandle eventIn | ( | const std::string & | n | ) | [virtual] |
Return a handle on the event in named n
of the node or a "unknown" typed handle if there is no such event. Valid names are:
Implements Node.
wrl::Node::EventInHandle eventIn | ( | unsigned int | n | ) | [virtual] |
Return a handle on the i
th event in of the node or a "unknown" typed handle if there is no such node. Here is how i
is related to fields:
This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.
Implements Node.
unsigned int nbEventsOut | ( | ) | const [inline, virtual] |
Returns the number of events out for this node type.
Implements Node.
wrl::Node::EventOutHandle eventOut | ( | const std::string & | n | ) | [virtual] |
Return a handle on the event out named n
of the node or a "unknown" typed handle if there is no such event. Valid names are:
Implements Node.
wrl::Node::EventOutHandle eventOut | ( | unsigned int | n | ) | [virtual] |
Return a handle on the i
th event out of the node or a "unknown" typed handle if there is no such node. Here is how i
is related to fields:
Implements Node.
const char * typeName | ( | ) | const [inline, virtual] |
Returns "NurbsGroup"
. Useful for printing.
Implements Node.
wrl::Node * duplicate | ( | ) | const [virtual] |
Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos.
Implements Node.
