Point Clouds, Part 1
This chapter brings us into the world of 3-D. You will see what the different ways of representing 3-D data are and how we can transform the 2-D images returned by the Kinect into 3-D points. This chapter will include the following concepts:
- Representing data in 3-D
- Transforming a depth image into a point cloud
- Visualizing a point cloud
- Coloring a point cloud
- Manipulating a point cloud
Let’s get started.
Representing Data in 3-D
Before you start producing 3-D models with your Kinect, you must know how to represent and store those models. Most developers are familiar with how 2-D raster images are stored. The image consists of a regular grid of pixels that sample the 2-D space. The image resolution (i.e., ...
