pyFM.mesh.file_utils.read_obj

pyFM.mesh.file_utils.read_obj(filepath, load_normals=False, load_texture=False, load_texture_normals=False)

Read a .obj file containing a mesh.

Parameters:

• filepath (str) – path to the .obj file

• load_normals (bool, optional) – whether to load vertex normals if present

• load_texture (bool, optional) – whether to load texture coordinates if present. Reads both uv coordinates and face to texture vertex indices

• load_texture_normals (bool, optional) – whether to load texture normals if present. Reads face to texture normal indices

Returns:

• vertices (np.ndarray) – (n,3) array of vertices coordinates

• faces (np.ndarray) – (m,3) array of indices of face vertices, None if not present

• normals (np.ndarray, optional) – Only if load_normals is True. (n,3) array of vertex normals, None if not present

• uv (np.ndarray, optional) – Only if load_texture is True (n,2) array of uv coordinates, None if not present

• fvt (np.ndarray, optional) – Only if load_texture is True (m,3) array of indices of face to vertex texture (vt) indices, None if not present

• fnt (np.ndarray, optional) – Only if load_texture_normals is True (m,3) array of indices of face to texture normal indices, None if not present
