This property node defines a texture map and parameters for that map. This map is used to apply texture to subsequent shapes as they are rendered.
The texture can be read from the file specified by the filename field. Once the texture has been read, the image field contains the texture data. However, this field is marked so the image is not written out when the texture node is written to a file. To turn off texturing, set the filename field to an empty string ("").
Textures can also be specified in memory by setting the image field to contain the texture data. Doing so resets the filename to the empty string.
If the texture image's width or height is not a power of 2, or the image's width or height is greater than the maximum supported by OpenGL, then the image will be automatically scaled up or down to the next power of 2 or the maximum texture size. For maximum speed, point-sampling is used to do the scale; if you want more accurate resampling, pre-filter images to a power of 2 smaller than the maximum texture size (use the OpenGL glGetIntegerv(GL_MAX_TEXTURE_SIZE...) call to determine maximum texture for a specific OpenGL implementation).
The quality of the texturing is affected by the textureQuality field of the SoComplexity node. The textureQuality field affects what kind of filtering is done to the texture when it must be minified or magnified. The mapping of a particular texture quality value to a particular OpenGL filtering technique is implementation dependent, and varies based on the texturing performance. If mipmap filtering is required, mipmaps are automatically created using the simple box filter.
