Public Attributes

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.

SFFloat radius

Detailed Description

Here is the documentation for this node type, from the ISO standard.

+6.62 Sphere

The Sphere node specifies a sphere centred at (0, 0, 0) in the local coordinate system. The radius field specifies the radius of the sphere and shall be greater than zero. Figure 6.15 depicts the fields of the Sphere node.

Sphere node

Figure 6.15 -- Sphere node

When a texture is applied to a sphere, the texture covers the entire surface, wrapping counterclockwise from the back of the sphere (i.e., longitudinal arc intersecting the -Z-axis) when viewed from the top of the sphere. The texture has a seam at the back where the X=0 plane intersects the sphere and Z values are negative. TextureTransform affects the texture coordinates of the Sphere.

The Sphere node's geometry requires outside faces only. When viewed from the inside the results are undefined.

Constructor & Destructor Documentation

Sphere const char *  name = ""  ) 
 

Construct a node with all its fields set to default value, which is equivalent to the code below:

  radius = 1;

~Sphere  )  [virtual]
 

Virtual destructor, does nothing


Member Function Documentation

wrl::Node * duplicate std::map< const Node *, Node * > &   )  const [virtual]
 

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.

wrl::Node::EventInHandle eventIn const unsigned int  i  )  [virtual]
 

Return a handle on the i th event in of the node or a "unknown" typed handle if there is no such node. emarks This class has no eventIn. This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.

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::EventOutHandle eventOut const unsigned int  i  )  [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: This function is useful, with nbEventsOut() if you want to traverse all events in of a Node.

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::FieldHandle field const 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:

  • 0 : radius This function is useful, with nbFields() if you want to traverse all fields of a Node.

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:

  • radius

Implements Node.

bool isSetToDefaultValue const 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.

unsigned int nbEventsOut  )  const [inline, virtual]
 

Returns the number of events out for this node type.

Implements Node.

unsigned int nbFields  )  const [inline, virtual]
 

Returns the number of fields (exposed or not) for this node type.

Implements Node.

const char * typeName  )  const [inline, virtual]
 

Returns "Sphere". Useful for printing.

Implements Node.
