We are happy to announce that X3DOM now features a first implementation of the ClipPlane node.
In addition to the default X3D description, which contains the enabled and plane attributes (describing orientation and translation of the clip plane), X3DOM introduces two additional attributes: cappingStrength and cappingColor. Those two can be used to render parts of the object next to the cut with a special color of your choice.
Check out the example to see how it works!
