The question

能否在保证渲染质量的同时,做到实时新视角合成,而不是离线慢渲染?

What they did

用各向异性 3D 高斯显式表示场景,光栅化替代体渲染。

Evidence

视觉质量接近 NeRF,渲染速度提升到实时量级。

Do not over-trust

薄壁、反光金属、细线缆是弱项;位姿不准时,重影会伪装成“缺陷”。

Limits

依赖准确位姿与较多视角;无几何保证,不能直接当尺寸测量依据。

In-class task

用一段桨叶环绕视频重建,测量已知标记点间距,报告相对误差。

A foundation paper is the landmark work for a method and stays permanently: it explains why the method works, and is never replaced for being old.
