+What is PCL?
+============
+
+The Point Cloud Library (or PCL) is a large scale, open project [[1]](#open) for 2D/3D
+image and point cloud processing. The PCL framework contains numerous
+state-of-the art algorithms including filtering, feature estimation, surface
+reconstruction, registration, model fitting and segmentation. These algorithms
+can be used, for example, to filter outliers from noisy data, stitch 3D point
+clouds together, segment relevant parts of a scene, extract keypoints and
+compute descriptors to recognize objects in the world based on their geometric
+appearance, and create surfaces from point clouds and visualize them -- to name
+a few.
+
+PCL is released under the terms of the [3-clause BSD license](https://en.wikipedia.org/wiki/BSD_licenses#3-clause_license_.28.22Revised_BSD_License.22.2C_.22New_BSD_License.22.2C_or_.22Modified_BSD_License.22.29) and is open source software. **It is free for commercial and research use.** PCL is **cross-platform**,
+and has been successfully compiled and deployed on Linux, MacOS, Windows and
+Android. To simplify development, PCL is split into a series of smaller
+code libraries, that can be compiled separately. This modularity is important
+for distributing PCL on platforms with reduced computational or size
+constraints (for more information about each module see the [documentation]({{ site.api_base_url }})
+page). Another way to think about PCL is as a graph of code libraries,
+similar to the [Boost](http://www.boost.org/) set of C++ libraries. Here's an example:

+
+
+What is a Point Cloud?
+======================
+
+A point cloud is a data structure used to represent a collection of
+multi-dimensional points and is commonly used to represent three-dimensional
+data. In a 3D point cloud, the points usually represent the X, Y, and Z
+geometric coordinates of an underlying sampled surface. When color information
+is present (see the figures below), the point cloud becomes 4D.
+
+![point_cloud_example](/assets/images/about/point_cloud_example.png)
+
+
+Point clouds can be acquired from hardware sensors such as stereo cameras, 3D scanners, or time-of-flight cameras, or generated from a computer program synthetically. PCL supports natively the OpenNI 3D interfaces, and can thus acquire and process data from devices such as the PrimeSensor 3D cameras, the Microsoft Kinect or the [Asus
+XTionPro](https://www.asus.com/3D-Sensor/Xtion_PRO/).
+
+For more information about point clouds and 3D processing please visit our [documentation]({{ site.api_base_url }}) page.
