public record class VirtualShadowAsset

The sun's shadow as a virtual map: doc 22 phase 7.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

ShadowMapAsset's replacement rather than its sibling. Four cascades are four fixed resolutions over a whole frustum, and a virtualized scene's geometry is finer than any of them — so the cascade's own texel size becomes the visible limit. This fits a clipmap instead, and allocates only the pages some pixel actually asked for. A document with both nodes in it renders two shadow maps and shades from the virtual one wherever it has a drawn page, which is the fall-through ClusteredShading.Shadow is written for.
