THREE.JS / FOUNDATIONS 88

Budget the target.

Render-target choices multiply quickly. This lab estimates attachment bytes, allocates the selected target, and compares the estimate with Three.js’ tracked renderer memory and backend limits.

Estimated attachment bytesresolved + MSAA model

The estimate is explicit: RGBA8 = 4 B/px, RGBA16F = 8 B/px, depth16 = 2 B/px, depth32 = 4 B/px.

Budget lifecycle

estimate→allocate→render→dispose

The estimator is a planning model; `Info.memory` is the observed renderer counter.

Change the configuration, allocate the target, inspect the preview, then dispose it to verify lifecycle.
