Focus Stories

Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in GIM International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for January 2016 is:

Photogrammetry and Point Clouds

What is a Point Cloud?

A point cloud is basically a large collection of points that are placed on a three-dimensional coordinate system. Point cloud files greatly speed the design process by providing real-world context where you can re-create the referenced objects or insert additional models. Point clouds are derived from raw data gathered by using a 3D scanner to obtain points from such things as buildings, topographies, or manufactured items.
