Abstract	In volume-rendering applications an appropriate resampling filter is usually chosen by making a compromise between quality and efficiency. Generally, the fine details can be reconstructed by filters of wider support that can better approximate the ideal low-pass filter. On the other hand, if the data is noisy, a filter of a good pass-band behavior might even emphasize the noise. Therefore, to visualize noisy data, a filter of a higher smoothing effect is more favorable. Thus, the choice of the reconstruction filter depends on the quality of the data and the purpose of the visualization as well. In this paper, we propose a scalable volume-rendering technique for interactively controlling the frequency-domain behavior of the reconstruction. Applying our method, the trade-off between the smoothing and postaliasing effects can be set on the fly by using a single slider.
