Texture files?

[antithing]

Hi, and thank you for this code.
Do the extracted human models include texture?

What format can be exported? Mesh with texture? Or neural representations?

Thanks!

Hi, the extracted human meshes do not incluu textures. We save the checkpoints of the neural representations for rendering with textures.

Thank you. What neural representation is used? Gaussian? Or sdf?

Can these be exported for rendering in other applications?

We are using the SDF representation. We export the untextured mesh from SDF field here:

HSR/hsr/models/hsr.py

Lines 816 to 838 in 67813c1

	mesh_canonical = mesh_utils.generate_mesh(
	lambda x: self.query_fg_oc(x, cond),
	self.model.smpl_server.verts_c[0],
	point_batch=10000,
	res_up=3,
	)
	verts_mesh = torch.tensor(
	mesh_canonical.vertices, dtype=torch.float32, device=self.device
	).unsqueeze(0)
	mesh_canonical = trimesh.Trimesh(
	mesh_canonical.vertices,
	mesh_canonical.faces,
	)
	smpl_outputs = self.model.smpl_server(
	inputs["smpl_scale"], inputs["smpl_trans"], inputs["smpl_pose"], inputs["smpl_shape"]
	)
	smpl_tfs = smpl_outputs["smpl_tfs"]
	verts_deformed = self.get_deformed_mesh(mesh_canonical.vertices, cond, smpl_tfs)
	mesh_deformed = trimesh.Trimesh(vertices=verts_deformed, faces=mesh_canonical.faces)
	mesh_scene = mesh_utils.get_surface_sliding(
	lambda x: self.query_bg_sdf(x, None), resolution=512, grid_boundary=[-3.0, 3.0]
	)

For rendering, I would recommend doing volume rendering with the SDF representation.
