The Subtle Perils of GPU Perspective-Correct Interpolation
GPU 원근 보정의 함정: 비트 정밀도가 깨지는 원인과 대응법
Why it matters
This technical investigation reveals how GPU perspective-correct interpolation can introduce floating-point jitter, preventing bit-perfect constants from reaching the fragment shader. For developers, this hardware-level imprecision necessitates defensive rendering techniques like adding offsets to avoid elusive visual artifacts.
