Appeal No. 1998-0426
Application No. 08/307,028
displayed surface generated. (See brief at page 4.) We agree with appellant that the
claimed invention is directed to spherical volumes with a nonuniform density.
The examiner relies upon Sakas to teach the use of a nonuniform density function in
3-D modeling smoke and clouds. While Sakas discloses the use of 3-D models and
projection of the model onto the screen (see Sakas figure 2), Sakas does not disclose the
use of a sphere, with a center point, as the object being modeled or the computations
recited in claim 1. While Sakas does teach the use of density functions, in our view, Sakas
does not remedy the above deficiencies in Gardner. Therefore, we will not sustain the
rejection of claim 1 and dependent claims 2-5.
CONCLUSION
To summarize, the decision of the examiner to reject claims 1-5 under 35 U.S.C. §
103 is reversed.
