Stupid question, but what is Ortho projection and how do I use it in CR? I do 3D scans mostly of people and wondering if this will help.
Thanks

Hi Scotth
There is no stupid question
An ortho projection is used to get 2D representation of 3D models for creating CAD models and so on. There is very little use for full-body scanning, except exporting a front view of the model as an image without any distortion.

Hello Scotth,
actually, the correct term is ortographic projection: https://en.wikipedia.org/wiki/Orthographic_projection
Sorry for reviving this old thread but I was wondering if it’s possible to create an orthographic projection without first creating a 3D model? So basically just stitching together the aerial photos.
I don’t like the current workflow because the 3D model will no always be perfect (like holes under trees for example).
hello Tomas,
RealityCapture creates projections from a 3D model
Hello Lucia,
Thank you for your reply.
That’s a bummer! Those projections would be so much cleaner (and faster to process) if they weren’t being made from the 3D model.
