Grassmannian Splatting 推进动态场景渲染,采用新颖时空图元

研究人员推出 Grassmannian splatting,一种用于渲染动态场景的新颖方法。该技术利用秩为 2 的时空曲面元(spacetime surfels),它们本质上是时空中均匀移动的二维圆盘。与之前对全秩时空协方差进行切片的方法不同,Grassmannian splatting 以时间为条件生成秩为 2 的曲面元,从而实现更高效且闭式的运动模型。该方法在 MonoDyGauBench 数据集上展示了显著更快的训练时间,速度比强大的基线快 4.9 到 5.6 倍,同时保持了具有竞争力的视觉质量。 AI

影响 引入了一种新的渲染技术,显著加快了动态场景重建的训练速度。

    Grassmannian Splatting I: 动态场景渲染的移动二阶时空曲面元

    arXiv:2607.10489v1 Announce Type: new Abstract: We introduce Grassmannian splatting, a dynamic scene representation whose primitives are Gaussians supported on 3-planes in spacetime $\R^4$: generically, spatial 2-planes in uniform translation along their normals. Each primitive c…
