A '.ply' extension will be appended to the file name if it does no already have one. field_list : list, tuple, numpy array the fields to be saved in the ply file. Either a numpy array, a list of numpy arrays or a tuple of numpy arrays. Each 1D numpy array and each column of 2D numpy arrays are considered as one field. field_names : list the name of each fields as a list of strings. Has to be the same length as the number of fields. Examples -------- >>> points = np.random.rand(10, 3) >>> write_ply('example1.ply', points, ['x', 'y', 'z']) >>> values = np.random.randint(2, size=10) >>> write_ply('example2.ply', [points, values], ['x', 'y', 'z', 'values']) >>> colors = np.random.randint(255, size=(10,3), dtype=np.uint8) >>> field_names = ['x', 'y', 'z', 'red', 'green', 'blue', values'] >>> write_ply('example3.ply', [points, colors, values], field_names) rrz"fields have more than 2 dimensionsFcSsg|]}|jdqS)rr9.0r@rrr szwrite_ply..rzwrong field dimensionscSsg|]}|jdqS)rrCrDrrrrFszwrong number of field namesz.plywZplyzformat binary_z _endian 1.0Nzelement face {:d}z&property list uchar int vertex_indicesZ end_headerz%s ab)r()r*uint8cSsg|]}t|dfqS)int32)str)rEindrrrrF;sr*012T) typelisttuple enumeratendimreshapeprintr0allequalsumlenendswithr.rsys byteorderextendrAformatr9writer3r(rKemptytofileastyperJrangefullrI)r4r;r<Ztriangular_facesr>r@n_pointsn_fieldsrheaderrZ type_listr?r7rrr write_plysf"*              rjcCsdddd}d|dtt|g}|dkr:|dnHtt|jD]8}|t|j|d }|d |d|jj|qH|S) z Takes the columns of the dataframe and builds a ply-like description Parameters ---------- name: str df: pandas DataFrame Returns ------- element: list[str] floatZucharr)fur>zelement  r"z&property list uchar int points_indicesrz property )rKr[rrecolumnsdtypesvalues)r:dfZproperty_formatselementr>rlrrrdescribe_elementFs   rt)F)N) numpyr0r]dictrr/r r&r8rArjrtrrrrs8 !
