Appearance node

Appearance {
  SFNode material NULL
  SFNode texture NULL
}

The Appearance node is used in a Shape to handle the Shape's appearance field.

Some restrictions may apply depending of the geometry node associated to the Shape and or on the current 2D/3D context.

SFNode material NULL :
The field material can be set to a Material2D in a 2D context.

SFNode texture NULL :
The field texture can be set to an ImageTexture or a MovieTexture.

# Shape with an Appearance using a Material2D
# to draw a simple red rectangle.
Shape {
  appearance Appearance {
    material Material2D { emissiveColor 1 0 0   filled TRUE }
  }
  geometry Rectangle { size 150 150 }
}

# Shape with an Appearance using a ImageTexture
# to render an image.
Shape {
  appearance Appearance {
    texture ImageTexture { url "icon.png" }
  }
  geometry Rectangle { size 50 50 }
}

Note for emissiveColor : values are between 0 and 1. so, if you have RGB triplets, divide each value by 255 and you're done.
