gpu-curtains/dist/esm/core/shaders/chunks/fragment/head/get-fragment-input-struct.mjs

gpu-curtains is a 3D WebGPU rendering engine. It can be used as a standalone 3D engine, but also includes extra classes focused on mapping 3d objects to DOM elements; It allows users to synchronize values such as position, sizing, or scale between them.
