I was going through the following wonderful Colab Notebook,
PyTorch3D · A library for deep learning with 3D data 2
This colab only has the code without the outputs. My personal copy of this Colab Notebook with outputs can be found below,
Copy of render_textured_meshes.ipynb - Colaboratory (google.com) 1
And when I executed the cell
plt.figure(figsize=(7,7))
texture_image=mesh.textures.maps_padded()
plt.imshow(texture_image.squeeze().cpu().numpy())
plt.grid("off");
plt.axis("off");

It gave the following output,

and when I ran the following cell,
plt.figure(figsize=(7,7))
texturesuv_image_matplotlib(mesh.textures, subsample=None)
plt.grid("off");
plt.axis("off");

it gave the folowing,

Can someone explain what these output images mean or denote?
Thankyou very much.
