technical statement Leger's drawing is rather straightforward, for a cubist piece, but does require some analysis as to the meaning of each element. After analyzing what each item "is", it was modeled within the computer in 3D space with the same sense of weight, volume, emphasis, opacity, surface, dimension, etc. It simply became a mater of observation, construction, texturing, lighting and placement. The fully dimensional items were all assembled to match the drawing, but the camera was placed a great distance away with a field of view of less than 10 degrees. This telephoto lens collapsed the sense of depth so that the perspective in the "front" view was as "flat" as the drawing. Thereafter, with a normal lens on the camera, I moved around the still life; overhead, three-quarter, behind etc. Further, I realized that it should now be possible to view the scene stereoscopically. Bringing in stereoscopic imaging expert Gerald Marks (www.pulltime3d.com), I was able to render the appropriate left and right eye views. Marks combined these views to produce anaglyphs; stereo images that can be viewed with red/blue glasses. The Anaglyph process has been used to view stereo for almost 150 years but has found renewed utility in digital multimedia and for the web. We are also planning to utilize other methods of stereoscopic display; including lenticular, vectograph, polarizing projection, shutter glasses and holography. |
