Wavefront files and Poser files manipulation library
Project description
This file is the README of the library pypos3d.
- INTRODUCTION: ================ This library is a port of the old DATA3D library of the OpenSource Pojamas project. I own both of them.
pypos3d aims to replace Pojamas.DATA3D library with a very close interface. Application ePOSER (in Eclipse RCP) is replaced by a new MMI concept based on LibreOffice/Python.
This Python library intends to give high level operations for some 3D files:
-
WaveFront Files (.OBJ and compressed .obz [gziped]):
- Read / Write
- Groups manupilation : add, remove, optimization, fusion
- High level method: Plane Split, Plane Slice, Remesh, Hole filling
All Wavefront functions (classes) are in the pypos3d.wftk package
-
Poser Files (.PZ3, .CR2, .PZZ, .CRZ, .PP2, .PPZ):
- Read / Write
- Actors, Props, Cameras, ... manipulations: add, remove, rename
- Morph report and morph report on alternate geometries
- Cleaning
All Poser functions (classes) are in the pypos3d.pftk packages
Initialy, Pojamas project was a Eclipse RCP application based on a SWT/Java3D MMI. For maintenance reason, this RCP application will be discontinued and shall be replaced by another one (cf. chapter 4 'GUI').
- INSTALLATION: ================
2.1 Library Installation:
The library shall be installed with pip:
python3 -m pip pypos3d
2.2 GUI Install:
First, download the relevant GUI distribution package from Source Forge: https://sourceforge.net/projects/pojamas/files/ Filename : PyPos3DLO-X.Y.Z.zip Unzip it in your usual work directory (anywhere, in fact)
-
On Linux (and probably Mac - To Be Confirmed): Install first the library and its dependencies Launch the GUI installer : PyPos3D-App-Installer.ods Clic on Check install first and then on Install Close LibreOffice
The installation is finished, you can use the PyPos3DLO.ods sheet
-
On Windows (and for pure LibreOffice Installation on Linux) You will need to extend the internal Python installation with the dependencies. Install the LibreOffice extension developed by Mauricio Baeza https://gitlab.com/mauriciobaeza/zaz-pip
Using ZazPip : Install numpy, scipy and xlrd
Launch the GUI installer : PyPos3D-App-Installer.ods Clic on Check install first and then on Install Close LibreOffice
The installation is finished, you can use the PyPos3DLO.ods sheet
- DESIGN: ========== The pypos3d Library has the following structure:
-
langutil : A personal generic package for some utilities
-
pypos3d.wftk : WaveFront manipulation package The main classes are pypos3d.wftk.WaveGeom and pypos3d.wftk.GeomGroup. Refer to WaveGeom documention for information
-
pypos3d.pftk : Poser files manipulation package
-
pypos3d.propslim : Decimation function (port of Michael Garland "SlimKit Surface Modeling Tools")
-
Dependencies :
- numpy
- scipy
- xlrd
- TESTS: ========= This library is tested with unitest with a target coverage rate over 80%. Unit tests are delivered in another package Installation and commissionning tests are performed on:
- CentOS 8, 7
- Fedora >30
- Microsoft Windows 10
- GUI: ======= As mentioned previously, the former Pojamas application was an Eclipse RCP (obsolete RCP3). In the future, a WxPython application is forseen. For tests purpose, a LibreOffice calc based GUI is proposed. Refer to: Pojamas for download The GUI requires LibreOffice >= 6.4 on Windows and LibreOffice >= 6.3 on Linux (CentOS > 7)
LICENCE: This library is delivered under the BSD license.
