Images show volume data that consist of billions of voxels rendered with our dynamic sparse octree approach. Our algorithm achieves real-time to interactive rates on volumes exceeding GPU memory capacity by far, tanks to efficient streaming and ray-casting solutions. Basically, the volume is only used at the resolution that is needed to produce the final image. Besides the gain in memory and speed, our rendering provides is inherently anti-aliased

Notations for the derivation (Inlay). A point is either lit (a) or shadowed (b, c). In the latter case, we further distinguish between penumbra (b) and umbra (c), depending on whether the light source is only partially or completely hidden.

Transmittance shadow maps use this information to attenuate light passing through semitransparent surfaces (shadows of the trees). We also show that the obtained volume estimation can be used for refraction (lion).
