A few snapshots from a 3D point cloud / 3D scan of this structure- in support of a rendering by a third party. (Snapshots are screen grabs from Autodesk RECAP)

There are drawings and then there are drawings that are used to construct drawings

10 Year Anniversary!

10 years ago today I formed Aaslestad Preservation Consulting llc to better pursue my interest in ways of capturing, understanding, and visualizing the built world. Its led me to some great collaborations in unique places. I’m very grateful and looking forward to new horizons under changing skies, somehow still afloat and seaworthy!

Snapshots of a 3D point cloud

Its admittedly pretty fun to fly around a house once you have the point cloud made, taking “pictures” that you couldn’t have snapped when you were actually on site without the use of a jetpack!

This is a house in West Haven, CT.

View of “internal organs”

Using a medical analogy to understand new ways of accessing point cloud data… The slide above shows the point cloud in RECAP software with the exterior envelope layer turned off, revealing the cluster of internal spaces.

The slides below show a series of “slices” taken vertically through the buildings at 1 meter intervals, from north towards the south and then from east proceeding towards the west.

Battered Dry Laid Stone Retaining Wall

Overlapping Photogrammetric systems

View of Point Cloud from side/rear

Spending a lot of time seeing how different photogrammetric systems and point cloud software packages speak to one another. sometimes the interface is elegant, sometime not so much…

I’m just sharing a few snap shots from favorite projects as the end of the year draws near… here are a few from the Alamo:
