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 |
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.
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.
Sphere | ( | const char * | name = "" |
) |
Construct a node with all its fields set to default value, which is equivalent to the code below:
radius = 1.0f;
~Sphere | ( | ) | [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 | 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.
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 | 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.
const char * typeName | ( | ) | const [inline, virtual] |
Returns "Sphere"
. 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.
See Detailed Description for meaning of this field. Default value is set to
radius = 1.0f;
