Abstract
The limited color spatial acuity of the human visual system is exploited to develop a more efficient algorithm for realistic image synthesis. A screen subdivision ray tracer is modified to control the amount of chromatic and achromatic detail present at the edges in an environment. An opponents color space (previously used to select wavelengths for synthetic image generation) is used to define the chromatic and achromatic channels present in the image. Computational savings achieved by the algorithm are discussed. A perceptual evaluation shows that image quality is not seriously degraded by the use of the technique.
