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.
