Detailed Description
TextureCoordinateGenerator supports the automatic generation of texture coodinates for geometric shapes.
This node only implements some of the modes that are specified in the X3D specification.
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.
The available modes in H3D API are:
| H3D API specific modes (not part of the X3D standard) | ||
|---|---|---|
| "GL_SPHERE" | Sphere mapping using the GL_SPHERE_MAP function in OpenGL. See documentation for glTexGen for details | |
| "MATRIX" | Specify directly the matrix for transforming from vertex coordinates to texture coordinates. The matrix values are given in the parameter field and 12 values are required. The resulting texture coordinates will be: s = p[0] * v.x + p[1] * v.y + p[2] * v.z + p[3] t = p[4] * v.x + p[5] * v.y + p[6] * v.z + p[7] r = p[8] * v.x + p[9] * v.y + p[10] * v.z + p[11] where p[i] is the i:th value of the parameter field and v is a vertex. | |
| X3D modes | ||
| "CAMERASPACEPOSITION" | Use the vertex position, transformed to camera space, as input texture coordinates | |
| "COORD" | use vertex coordinates | |
| "COORD-EYE" | use vertex coordinates transformed to camera space | |
| "CAMERASPACEREFLECTIONVECTOR" | Use the reflection vector, transformed to camera space, as input texture coordinates.>/tr> | |
| "CAMERASPACENORMAL" | Use the vertex normal, transformed to camera space, as input texture coordinates, resulting coordinates are in -1 to 1 range. | |
The parameter field gives input parameters that can be used by the algorithm specified by the mode field.
