<font color="#0000FF">NOTE:</font> This class does not exist in Open Inventor 10.0 and later.
This section describes the expected behavior of the node in a conforming X3D browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.

TextureCoordinateGenerator supports the automatic generation of texture coodinates for geometric shapes.
This node can be used to set the texture coordinates for a node with a texCoord field.
The mode field describes the algorithm used to compute texture coordinates, as shown in the table below.
mode | Description |
SPHERE | Creates texture coordinates for a spherical environment or "chrome" mapping based on the vertex normals transformed to camera space. u = Nx/2 + 0.5 v = Ny/2 + 0.5 where u and v are the texture coordinates being computed, and Nx and Ny are the x and y components of the camera-space vertex normal. If the normal has a positive x component, the normal points to the right, and the u coordinate is adjusted to address the texture appropriately. Likewise for the v coordinate: positive y indicates that the normal points up. The opposite is of course true for negative values in each component. If the normal points directly at the camera, the resulting coordinates should receive no distortion. The +0.5 bias to both coordinates places the point of zero-distortion at the center of the sphere map, and a vertex normal of (0, 0, z) addresses this point. Note that this formula doesn't take account for the z component of the normal. |
CAMERASPACENORMAL | Use the vertex normal, transformed to camera space, as input texture coordinates, resulting coordinates are in -1 to 1 range. |
CAMERASPACEPOSITION | Use the vertex position, transformed to camera space, as input texture coordinates |
CAMERASPACEREFLECTIONVECTOR | Use the reflection vector, transformed to camera space, as input texture coordinates. The reflection vector is computed from the input vertex position and normal vector. R=2 * DotProd(E,N) * N - E; In the preceding formula, R is the reflection vector being computed, E is the normalized position-to-eye vector, and N is the camera-space vertex normal. Resulting coordinates are in -1 to 1 range. |
SPHERE-LOCAL | Sphere mapping but in local coordinates |
COORD | Use vertex coordinates |
COORD-EYE | Use vertex coordinates transformed to camera space |
NOISE | Computed by applying Perlin solid noise function on vertex coordinates, parameter contains scale and translation [scale.x scale.y scale.z translation.x translation.y translation.z] |
NOISE-EYE | Same as above but transform vertex coordinates to camera space first |
SPHERE-REFLECT | Similar to "CAMERASPACEREFLECTIONVECTOR" with optional index of refraction, parameter[0] contains index of refraction. Resulting coordinates are in -1 to 1 range. |
SPHERE-REFLECT-LOCAL | Similar to "SPHERE-REFLECT", parameter[0] contains index of refraction, parameter[1 to 3] the eye point in local coordinates. By animating parameter [1 to 3] the reflection changes with respect to the point. Resulting coordinates are in -1 to 1 range |
