<p>Simulating a photographic camera for rendering two-dimensional images of virtual three-dimensional objects enhances flexibility and ease of use of a rendering sy stem. Simulating a photographic camera is performed by determining light from virtual light sources that passes through a lens of the simulated photographic camera having a n aperture, focus, and shutter speed and is incident upon the imaging plane within the camer a. The method also has application in teaching photography because, in some instances, computer simulation reduces the cost of equipment and consumables.</p> |
