Sponge render in color Sponge render in black and white
      This scene showcases a number of advanced features offered by LuxRender, including microdisplacement, loop subdivision, and layered materials. Microdisplacement subdivides and displaces individual triangles on-the-fly during ray intersections, allowing the creation of extremely high levels of detail without the need to store individual polygons. This technique is used to give the sponge mesh on the lower right a significant amount of detail, containing over 77 million triangles, three blended materials, and a homogeneous volume. Loop subdivision works similarly to microdisplacement, except that polygons are computed and stored prior to rendering. This technique was used to give the table on the lower third of the image over 40 million polygons of detail. The layered material allows LuxRender to reflect and transmit light through various materials as if one were layered on top of another. The layered material was used to create multiple layers on the sponge, where a glossy coating is placed atop a velvet material, a glossy transluscent material, and a homogeneous volume. It was also used on the paint palette on the lower left of the image, to depict dried paint atop a base metal material.
