The SoVRMLTextureCoordinate class binds texture coordinates to vertex-based geometry.
The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:
TextureCoordinate {
exposedField MFVec2f point [] # (-inf, inf)
}
The TextureCoordinate node specifies a set of 2D texture coordinates used by vertex-based geometry nodes (e.g., SoVRMLIndexedFaceSet and SoVRMLElevationGrid) 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 (SoVRMLImageTexture, SoVRMLMovieTexture, and SoVRMLPixelTexture) 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 (-inf,inf). 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 SoVRMLImageTexture, SoVRMLMovieTexture, and SoVRMLPixelTexture.

Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoNode.
This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
This static method returns the SoType object associated with objects of this class.
|
protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.
Reimplemented from SoFieldContainer.
|
staticprotected |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Returns the SoFieldData class which holds information about fields in this node.
|
virtual |
Action method for the SoGetPrimitiveCountAction.
Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.
Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables.
Reimplemented from SoNode.
|
virtual |
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.
Reimplemented from SoNode.
|
virtual |
Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
