Rubber and the Sunken Effect

Rubber and Sunken Effect is another filter that I created to show the capability of Inkscape in providing cool and elegant looking vector cliparts. As usual, you can get it in OCAL.

Basically the rubber and sunken effect can be achieved mainly through the manipulation of two Specular Lighting primitives and one Morphology primitive.

The morphology primitive is just there to create an eroded or smaller version of the original graphic; while the two specular light primitives are there to make sure that the highlight from the original graphic and the eroded graphic are opposite each other, thus producing the sunken effect.

Download the filter in OCAL and experiment to learn more.

For the guys out there who do not want to use a filter, you can create the effect by using gradients. Just make sure the direction of the gradients of the two graphics are opposite and your done. See the samples below.
