The output .ply. Could you explain what are they ? about mvster HOT 1 OPEN

1. "mvsnet_xxx_l3.ply" is the final point cloud output of the scan xxx, and other ply files (e.g., scan1/ply_local/00000000.ply) are the intermediate point clouds for simple visualization. To be more specific, to produce 00000000.ply, we run the model for 00000000.png (along with its source images) and generate the depth map for 00000000.png. Then we can convert the depth map to point cloud file 00000000.ply with the camera parameters. In contrast, to produce mvsnet_xxx_l3.ply, we have to run the model for every single frame (000000.png-xxxxxx.png), and generate depth maps for each of them, subsequently, these depth maps are fused to calculate the mvsnet_xxx_l3.ply.
2. mvsnetXXX_l3.ply is used to evaluate the DTU dataset for model comparison.

4. You can use Open3d to visualize these point clouds. For better visualization, you may want to visualize the whole point cloud of the scan (mvsnetXXX_l3.ply ), instead of the point cloud from a single depth map (0000000.ply).
