NeRF:一些工作尝试使用神经辐射场(NeRF)来高质量重建几何和外观,但由于体积渲染的高计算成本,难以实现实时性能,且内存成本过高。 3D 高斯表示:作为 NeRF 的替代表示,3D 高斯能够实现等同或更好的渲染质量,同时速度更快,但此前主要应用于离线重建场景,未适用于需要连续 RGBD 输入的在线重建任务。 基于NeRF 的RGBD ...
我们知道，最近两年，3D 生成的技术路线大致可以分为两类：2D 升维和原生 3D。2D 升维是通过 2D 扩散模型，结合 NeRF 等方法实现三维重建的过程。由于可以利用大量的 2D 图像数据进行训练，这类模型往往能够生成多样化的结果。但又因为 2D 扩散模型的 3D 先验能力不足，这类模型对 3D 世界的理解能力有限，容易生...

In this paper, we propose a real-time rendering method called PNeRF. PNeRF utilizes continuous polynomial functions to approximate spatial volume density and color information. Additionally, we separate the view direction information from the rendering equation, leading to a new expression for the ...
