2.3. Shadow Depth Maps 45

extreme care must be taken to avoid worsening quality for far-away points

that exhibit high-frequency shadow changes; thus, this technique may not

be appropriate for high-quality oine rendering scenarios.

● Z-partitioning shadow depth maps. isisanonwarpingalternativeap-

proach to mitigate perspective aliasing where zones along the Z-depth axis

are partitioned into separate depth maps, with high resolution focused on

the Z-depths closer to the camera view. is approach should produce better

quality than warping shadow depth maps, although at a slower performance

rate. Note that this approach is known by various names, including ...
