Training without Lidar points #11

Hi,

I have a quick question: You method seems to rely on Lidar points to intialize the gaussian blobs. Conventional 3DGS method works on randomly initialised point-cloud, I wonder if PVG can do that as well ? How does it affect the rendering results.

Hi, we have tested to train PVG with randomly initialized point cloud. It may produce bad depth map, while the rendering PSNR decrease slightly .

Hi, I wonder how can I do that with the current codebase ?
