Abstract: We propose a generic and flexible depth-cueing scheme which subsumes a large class of color-based depth-cueing approaches. In particular, it includes standard fog-based depth-cueing and widely neglected saturation depth-cueing. Our depth-cueing scheme is based on linear transformations in the 3D tristimulus space of colors and on weighted sums of colors. Since all of the required operations are supported by contemporary consumer graphics hardware, the depth-cueing scheme can be implemented with minimal reduction of performance. Therefore, any real-time rendering application can be enriched by sophisticated depth-cueing.
