visualization

[wwj-53]

May I ask how to visualize the constructed 3D model?

I have the same question.

grep -rwn . -e '.ply'

shows:

        if save_ply:
            points = self.gs_render.gaussians._xyz.detach().cpu().numpy()
            pcd_data = o3d.geometry.PointCloud()
            pcd_data.points = o3d.utility.Vector3dVector(points)
            pcd_data.colors = o3d.utility.Vector3dVector(np.ones_like(points))
            o3d.io.write_point_cloud(
                filename.replace('.png', '.ply'), pcd_data)

in cf3dgs_trainer.py and then there's the function called construct_point

I'm not quite sure when this is supposed to be invoked.
There's 3-4 more issues here on github asking the same question and were closed without a hint. :/

I add a command self.gs_render.gaussians.save_ply("point_cloud1.ply") after training codes just like the original gaussian splatting method, and using supersplat to visualize the .plyfile

Appended line to run_cf3dgs.py:

    trainer.gs_render.gaussians.save_ply(f'{model_cfg.source_path}/output.ply') # assuming global 3dgs

then training with

python run_cf3dgs.py -s ./drg/ --mode train --data_type custom

The results are not quite what I expected, which parameters should I inspect?
