The TextureCoordinate node specifies a set of 2D texture coordinates
used by vertex-based geometry nodes (e.g., IndexedFaceSet
and ElevationGrid) to map textures to vertices.
Textures are two dimensional colour functions that, given an (s, t)
coordinate, return a colour value colour(s, t). Texture map
values (ImageTexture, MovieTexture,
and PixelTexture) range from [0.0, 1.0] along
the S-axis and T-axis. However, TextureCoordinate values, specified by the
point field, may be in the range (-,
). Texture coordinates identify
a location (and thus a colour value) in the texture map. The horizontal
coordinate s is specified first, followed by the vertical coordinate
t.
If the texture map is repeated in a given direction (S-axis or T-axis), a texture coordinate C (s or t) is mapped into a texture map that has N pixels in the given direction as follows:
Texture map location = (C - floor(C)) × N
If the texture map is not repeated, the texture coordinates are clamped to the 0.0 to 1.0 range as follows:
Texture map location = N, if C > 1.0, = 0.0, if C < 0.0, = C × N, if 0.0 <= C <= 1.0.
Details on repeating textures are specific to texture map node types described in 6.22, ImageTexture, 6.28, MovieTexture, and 6.33, PixelTexture.
TextureCoordinate | ( | const char * | name = "" |
) |
Construct a node with all its fields set to default value, which is equivalent to the code below:
~TextureCoordinate | ( | ) | [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. 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 | 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 "TextureCoordinate"
. 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.
