I'm trying to texture a hexagonal pyramid with a png image. It's simple when its a 2 dimensional hexagon but I can't seem to understand the use of the <textureCoordinate/> node and what is defined in point

 <Shape DEF="Dodecahedron">

 <Appearance>
 <ImageTexture url="./shell-tex.png" />
 </Appearance>

 //Draws a hexagonal Pyramid
 <IndexedFaceSet
 solid="false"
 coordIndex=' 0 1 2 -1 0 2 3 -1 0 3 4 -1 0 4 5 -1 0 5 6 -1 0 6 1 -1' texCoordIndex="0 1 2 3 4 5 -1">
 <Coordinate point='0 0.5 0, 0 0 -1, 0.866 0 -0.5, 0.866 0 0.5, 0 0 1, -0.866 0 0.5, -0.866 0 -0.5'/>
 <TextureCoordinate point=""/>
 </IndexedFaceSet>
 </Shape>

When <textureCoordinate /> is empty the image maps onto the shape but the dimensions are off and the shape looks different but I want the image to map onto the shape with the shapes dimensions
