thank you all, I will try to implement the surface computation algorithm
immediately.

Subject: [JAVA3D] AW: [JAVA3D] volume and surface

> In order to compute the area covered by the Shape3D's geometry, you could
> sum up all the areas of the polygons that the shape consists of. A
> triangle's area can be calculated by the cross product between two of the
> triangle's edge vectors. The absolute length of the resulting vector is
the
> area. Further information can be found in section 2.01 of the
> comp.graphics.algorithms faq (see
> http://www.faqs.org/faqs/graphics/algorithms-faq/). There is also an
> algorithm for computing the volume of a polyhedron in section 5.19 of this
> faq. Probably this will help.
