Detailed Description

Data for a single shadow cascade. Contains render targets, matrices, and update state.

TIMING MODEL (Synchronous Capture):

We use manual CaptureScene() calls instead of bCaptureEveryFrame to ensure VP matrix and depth texture are always synchronized within the same frame.

Frame N timeline:

  1. Game Thread: Update() calculates VP_N and calls CaptureScene()
  2. Render Thread: Pre-pass ray march uses VP_N with Depth_N ✓

3. Render Thread: Post-process composite
