Surface Normals from downsampled image rays #106

Open Dharmendra04 opened 5 months ago

Dharmendra04 commented 5 months ago

In your method you downsampled the LLFF dataset by a factor of 8, thus, you have divided the projected pixels of each 3d points in the point clouds by the same factor. Will it means when the rays are shooter through this newly scaled pixels, it will meet the same exact 3d points of the point clouds before scaling?

Does this scaling by factor 8 mean scaling the entire scene in the world coordinate system by 8 in x,y and z direction?

I am using surface normals extraction, so I want to know whether this scaling would change my direction of the surface normals.

The rays will meet the same 3D points as expected.

Yes, scaling means applying the scaling factor to the world coordinate system.

I don't think the scaling would change the surface normals.
