large glb file

[monajalal]

How to open the large glb? Is there better suggestions for seeing the rendering?

(mapanything) mona@ada:~/3d_reconstruction/3d-recon-baselines/third_party/map-anything$ python scripts/demo_images_only_inference.py \
  --image_folder /home/mona/3d_reconstruction/data/mapanything_fullres500/images_500 \
  --viz \
  --save_glb \
  --output_path /home/mona/3d_reconstruction/data/run_03_downAisle/map_anything_cam0_500.glb

I ran this on 500 images and got the following glb:

[15:27:13] mona@DOS:~$ ls map_anything_cam0_500.glb
-rw-rw-r-- 1 mona mona 2.4G Mar  4 14:46 map_anything_cam0_500.glb

I tried to also convert it to obj and it didn't work. Blender also failed.

Also, is there a way to include image intrinsic to improve quality?

15:14:16] mona@DOS:~/glb_view/map_anything_cam0_500$ assimp export ~/map_anything_cam0_500.glb ~/map_anything_cam0_500.obj
param = /home/mona/map_anything_cam0_500.obj
assimp export: select file format: 'obj' (Wavefront OBJ format)

I converted it to ply but now after opening in meshlab I can barely rotate or zoom. Is there a way I could look at it like how we do for a splat.ply in superplat nodejs?

-rw-rw-r--   1 mona mona 2.4G Mar  4 14:46  map_anything_cam0_500.glb

-rw-rw-r--   1 mona mona 6.4G Mar  4 15:42  map_anything_cam0_500.ply

even trying to simplify the mesh by quadratic decimation and setting number of faces from 125M to 5M isn't helping as it crashes

eventually converted to 5M faces but the quality is very bad.

Please suggest how to get inference on my 500 images such that a reasonable supersplat friendly interactive end product can be produced.

Hi, thanks for trying out the code!

I would recommend taking a look at this demo and the voxelization support we have: https://github.com/facebookresearch/map-anything?tab=readme-ov-file#exporting-to-colmap-format

This should help with generating smaller .ply files which can be used with Splatting.
