## 6.67 TextureCoordinate

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.

## Constructor & Destructor Documentation

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

## Member Function Documentation

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:

- point

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:

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

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:

- set_point

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:

- point_changed

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:

- 0 : point_changed 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 `"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.

virtual Node* duplicate | ( | std::map< const Node *, Node * > & |  | ) | const`[virtual]`

Implements Node.
