Is this the same algo used for Magic Carpet (1994)? The style looks very familiar, and I always wondered how they pulled it off.
The voxel-style engines tend to feature a longer draw distance (due to it being cheaper to render, as you can easily use various hacks to eg. halve texture accesses far away).
For a detailed look into the rendering of Magic Carpet, start from Slide 8 of [2].
