Rendering mesh to mesh animation

[ggxxii]

Hi, thank you for making this amazing work open-source. For the animation part, you mentioned it's possible to render animation from mesh to mesh, I'm a bit confused, does this mean we need an obj sequence?

Hi, Thank you!

Not really. If you would like to render animation from mesh1 to mesh2, you need ... mesh1.obj and mesh2.obj. You can use this script (it has to be a bit changed, for your needs): https://github.com/waczjoan/gaussian-mesh-splatting/blob/main/scripts/render_from_mesh_to_mesh.py

For example, animation with opening ficus brushes needs:

• mesh1.obj (original mesh from dataset ---> ficus in t_0)
• mesh2.obj (final state of animation -- ficus with open brushes ----> ficus in t_n)

Then render frames for times: t_1, .... t_i, ... t_{n-1} is generated using interpolation.

So if I understand correctly, it's more like a mesh interpolation? And the transformation is linear?

in this case, for simplicity -- yes :)
