What does this PR do?

Introduces voxelization for 3D points before exporting them to the COLMAP format.

Why is it needed?

Exporting entire point clouds can result in excessively large files. Voxelizing the points beforehand provides users with an efficient way to downsample the data to their required density, reducing export time and file size.

Implementation Details

  • Integrates voxelization logic into the COLMAP export function.
  • Enables downsampling based on user-defined voxel size.
