Comments :
Texels are used to built complex geometries (foliage, grass, fur,
fabric, hair...) with a model looking like texture, with thickness.
Good properties are in the computation time, the image quality (few aliasing),
and more, the cost 'moralization' : cost is now linked to the visible
detail amount, and no longer to the database detail amount.
