3D models

Once a point cloud has been created, a less complex model can be extracted to aid in drafting and downstream workflows. At IRED we offer two choices, polygonal meshes (triangular/quadratic and watertight) or CAD solids. Each has individual benefits. 

Polygonal meshes

These meshes can be generated from the point cloud almost automatically. There is very little post-processing work, and meshes can be created for small objects (pipes, equipment) rather quickly. For larger objects (roadways, buildings), meshing may need to be broken into components, and the computational time increases.

CAD solids

This is the traditional CAD object, which can be imported into AutoCAD or Solidworks for further use. IRED has several level-of-details (LoD's) available for this format, as can be seen in pictures below. The time to create each model increases with an increase in LoD. Each model can be compared to the real world data found in the point cloud using distance computation software, allowing our engineers to create models as close reality as possible.
