pptk - Point Processing Toolkit

Copyright (C) 2011-2018 HERE Europe B.V.

The Point Processing Toolkit (pptk) is a Python package for visualizing and processing 2-d/3-d point clouds.

At present, pptk consists of the following features.

Install

One can either install pptk directly from PyPI

>> pip install pptk

or from the .whl file that results from building pptk from source.

>> pip install <.whl file>

Quickstart

In Python, generate 100 random 3-d points.

>> import numpy as np
>> x = np.random.rand(100, 3)

Visualize.

>> import pptk
>> v = pptk.viewer(x)

Set point size to 0.01.

>> v.set(point_size=0.01)

For more advanced examples, see tutorials.

Build

We provide CMake scripts for automating most of the build process, but ask the user to manually prepare dependencies and record their paths in the following CMake cache variables.

To set these variables, either use one of CMake's GUIs (ccmake or cmake-gui), or provide an initial CMakeCache.txt in the target build folder (for examples of initial cache files, see the CMakeCache.<platform>.txt files)

Requirements

Listed are versions of libraries used to develop pptk, though earlier versions of these libraries may also work.

Windows
  1. Create an empty build folder
>> mkdir <build_folder>
  1. Create an initial CMakeCache.txt under <build_folder> and use it to provide values for the CMake cache variables listed above. (e.g. see CMakeCache.win.txt)

  2. Type the following...

>> cd <build_folder>
>> cmake -G "NMake Makefiles" <source_folder>
>> nmake
>> python setup.py bdist_wheel
>> pip install dist\<.whl file>
Linux

Similar to building on Windows.
