This paper describes a wavelet-based ray-tracing algorithm that carries
out high quality images. Our appoach takes advantage of the
multiresolution representation of the volume data and the self-similarity
of the basis functions. The results are flexible high order approximations
of the low albedo rendering equation. We propose accurate integration and
evaluation schemes for shading and intensity computation. This paper also
describes the calculation of error bounds of the intensity integration.
The theory and its implementation are discussed and shaded images are
