A minimal ply conversion tools
seplot is a frontend for PyX to create plot from text files in command line or through a python interface. Developed by Serge Dmitrieff. https://www.biophysics.fr
Installing with pip3 (recommended)
$ pip3 install ply_convert
ply_convert requires Sklearn, Numpy, plyfile, and sio_tools. They will be downloaded when installed with pip3.
ply_convert [INPUT_FILE [INPUT_FILE_2 _3 ... ]] [out=OUTPUT_FILE] [OPTION=VALUE] [-ADDITIONAL_OPTIONS]
Options are to be written as opt=value or -option Unless mentioned otherwise, options are not applied by default Supported options : out= : name of output file (single file job) // extension of output file (multiple files) scale= : scale to be applied to points (float or 3x1 vector) length= : length of object on dimension of maximal variance thickness= : adds to each point a vector thickness*normal batch= : apply to all files of a certain type path= : path in which to look for files for batch operation label= : label of mesh, added when saving mesh files orientation= : orientation of normals (+1 : towards outside, -1 : towards inside) prefix= : add a prefix to output file name (multiple files) suffix= : add a suffix to output file name (multiple files) -center : center the data around [0,0,0] -align : aligns data to dimension x -normals : computes normals from faces -verbose : verbose output -fixnorms : makes sure normals are inwards (equivalent to option orientation=-1) -fixuint : fixes format to meshlab-friendly batch= : extension of files to process in batch (support multiple) ** batch only ** path= : folder in which to look for files (support multiple) include= : string that *must* be included in file name (support multiple) exclude= : string that *must not* be included in file name (support multiple) -recursive : searches recursively for files
ply_convert file.ply out=file.mesh
converts a ply file file.ply to a mesh file file.mesh
ply_convert.py file.mesh normals=1 out=file.ply
converts a mesh file to a ply file, and computes the normal at each point
ply_convert file_1.ply file_2.ply file_3.ply out=.mesh
converts file_1.ply file_2.ply file_3.ply into mesh files
ply_convert file.ply -center -align -normals length=7 -verbose thickness=0.15 scale='1.0 1.0 2.0' verbose=1 out=thickened.mesh out=thickened.ply
converts a ply file to a ply and a mesh file after centering, aligning, computing normals, scaling the object to a length of 7, and adding an extra thickness of 0.15, then scaling the z axis with a factor 2
ply_convert.py batch=.ply path='/home/user/simulations/' out='.ply' scale=0.1 -recursive prefix=scaled_
Recursively find ply files in '/home/user/simulations/', scales them to a factor of 0.1, and saves them to FOLDER/suffix_NAME.ply with NAME the filename and FOLDER the folder name
ply_convert.py file.ply out=fixed_file.ply -fixuint
fixes the header of a mesh file saved by tinyply (C++) so that it doesn't crash with meshlab.
