If you've ever wanted to create a 3D mapping on an object, this software can be a cost-effective key tool and wayopener to do it.

But first and foremost, the software is a very practical tool for converting any objects or landscape sections from photos or videos into 3D data.
So to create a 3D model out of a set of photos of a real object or a landscape section, to create your own contents & footages, e.g. in Blender.

Or for quickly creating backgrounds or complet environments for 3D scenes, by doing your own made HDR panoramas or hdri's.

& you can easily create the photos or videos with your cheap smartphone; the shots don't have to be extremely high-quality, but rather, you should take as many shots as possible.

Magic? No!
That's what it's about:
Photogrammetry is the science of making measurements from photographs. It infers the geometry of a scene from a set of unordered photographies or videos. Photography is the projection of a 3D scene onto a 2D plane, losing depth information. The goal of photogrammetry is to reverse this process.

The dense modeling of the scene is the result yielded by chaining two computer vision-based pipelines:
“Structure-from-Motion” (SfM) and “Multi View Stereo” (MVS).

Photogrammetry for Projection Mapping
It's best to study this introduction to familiarize yourself and get the necessary information.

ut one thing in advance: It's a tough, rocky road to the goal, but you can do it & if you rock that you can truly claim to have mastered video mapping and projection mapping. Everything else that is commonly referred to as mapping, i.e. projecting a few image sections onto various stage elements or deliberately onto a 3D go-kart construct confusing visauals like moast in the goa-scene we see, is a complete joke in comparison.

But I just wanted to give you the free tools to get you there. Now you have to be willing to put in the work.

The software presented here is for Windows/Linux, but for Mac & OSX, you can use "Apple's Object Capture" as a photogrammetry tool.
