我们把2dgs适配了鱼眼,而且鱼眼的Fov超过了180度。一个困惑的现象是,当2d高斯处在鱼眼180度fov附近时,投影在图像上就不正常了,2d高斯的投影的中心, aabb都不太对,以及最终渲染的结果会覆盖很大一片图像区域。具体的结果和实现我们搞了一个python版本的colab,麻烦大佬看一下2dgs-fisheye

Since we use ray-splat intersection for rasterizing Gaussian, so I think you can generate ray like nerf-based method for fisher-eye camera.
