Question about 3D Visualization

[Boey-li]

Hello, thanks for the amazing work! I have similar questions with the #13 , where I can not reproduce the 3D visualization using the sintel_bandage_3d.npy and the blender script. I have met the issue

 File "/Users/baoyu/research/visualizer/create.py", line 62, in <module>
    obj = bpy.data.objects[basename]
KeyError: 'bpy_prop_collection[key]: key "assets/sintel_bandage_3d_2" not found'

Do you have any sense for such bug?

And I also tried to visualize the 3D tracking performance using Open3D and sintel_bandage_spatracker_tracks.npy but the results are not good as you showed in the website. Can you also provide the 3D visualization code using Open3D if possible?

Thanks!

Hello!

I also faced a similar issue and, after investigating the keys of bpy.data.objects dict, the solution was to extract the filename's stem:
obj = bpy.data.objects[basename[basename.rfind('/')+1:]]
Hope it helps!

Hello! 你好！

i have some issues with 3d visualization. i wonder what bpy version did you use

[mgladkova]

I use the latest blender version 4.2.1 and launch the command as described in readme.

I use the latest blender version 4.2.1 and launch the command as described in readme.我使用最新的 blender 版本 4.2.1 并按照自述文件中所述启动命令。

shoot! i rewrote some of the scripts to make it run. did you use the bpy or the scripting in blender4.2

I am having error in 4.2.1:

File "/media/ed/FSSD/DATA/GITHUB/SpaTracker/blender_vis/create.py", line 38, in
rgb = data[:,:,[3,4,5]]
~~~~^^^^^^^^^^^^^
IndexError: index 3 is out of bounds for axis 2 with size 3

I am also getting something similar with

IndexError: index 7 is out of bounds for axis 0 with size 7

use another saved npy

[qinghew]

if the input is relative path, basename = args.input.split('.')[0] will split the first "." in "./vis_blender..." out. And basename will equal " ".

[qinghew]

my blender version is 4.2.1
refer:

1. Asking about the visualization code #13 (comment)
2. Question about 3D Visualization #31 (comment)

when edit the code "basename = basename.split('\')[-1]", it is related to your path.
for example, my path is "/user/xxx/data_process/vis_blender/vis_results/s023_04061_3d.npy", the code should be :
basename = basename.split('/')[-1]

3. if you meet the error:
   Traceback (most recent call last):
   File "/Users/qinghewang/Documents/codes/data_process/vis_blender/create.py", line 79, in
   group_input = node_tree.nodes['Group Input']
   ~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^
   KeyError: 'bpy_prop_collection[key]: key "Group Input" not found'
