A General Breakdown of the Shading Process
By utilizing the techniques described at left, we were able to create realistic surfacing illusions by projecting shaded renderings through the Davis and Sony projectors. Furthermore, we experimented with animation techniques by simulating the weathering process of stone. By varying the parameters passed into the stone shading routine, we generated two images. The first image showed very subtle signs of aging, while the deterioration of the surface in the second image was more pronounced. By using Adobe Premiere, we were able to generate a 15-second animation that employed a cross-dissolve transition to gradually fade from the first image into the second. By projecting this image through the Davis Projector, we simulated the aging of the physical model itself. It is important to note that this movie was generated solely for the Davis Projector. While a similar movie could have been created for use through the Sony, synchronizing the two animations would likely have proven difficult.
