# Early-Z

> **이 문서는 [[Depth Pre-Pass]] 의 중복본입니다.** Canonical 문서로 redirect.

## 핵심 요약
- Early-Z = depth test 매 fragment shader 이전에 실행 → occluded fragment 매 shader 실행 skip.
- 조건: `discard` / depth write in shader 매 없을 때 GPU가 자동 활성화.
- Depth Pre-Pass 매 Early-Z를 maximize 하는 standard pattern (z-only first pass → color pass).

## 🔗 Graph
