ImageTexture Node

This node specifies the location of the image to be used for texturing the shape, as well as if the image is to be repeated vertically, or horizontally, along each of the faces of the shape.

Three fields are present in this node:

url which specifies the location of the image. Valid image formats are JPEG, GIF and PNG. You can specify multiple locations if you want to, the browser will look for data in those locations in decreasing order of preference.

repeatS which specifies if the image is to be repeated vertically.

repeatT which specifies if the image is to be repeated horizontally.

All fields are optional, the default values being applied if the field is not specified. Note: if you do not specify the location of the image, url, then no texturing takes place.

Syntax:

ImageTexture {

url [ ]

repeatS TRUE

repeatT TRUE

}

Image File Formats in VRML The following formats should be recognized by VRML browsers:

JPEG, JPG: Joint Photographic Experts Group

GIF: Graphical Interchange Format

PNG: Portable Network Graphics

From the above formats JPEG is the only one which does not allow images to have transparent pixels.

Note: for the example on the right the image will be repeated twice in each direction if the values for repeatS and repeatT are set ot TRUE. See the node TextureTransform to see how to set the repetition rate.
