Photogrammetry

Photogrammetry is

producing realistic 3D models by processing large number of photos of a real-life object

Examples ..

from small to very large

Sources

Sketchup 3D warehouse              Sketchfab

 

 

                                              Use Unity plug-in

Unity claims to

understand Sketchup

file format       

 

 

Photogrammetry Software

There are a lot of software packages and a ridiculous number of file formats.

Free Setup

I use this free workflow method, but please research your own:

 

 

 

Good Training Videos

Only supports 50 photos

Exports directly to SketchFab

Sketchfab Free:

Limit of 50mb model

 

 

 

 

 

 

Photographs

        take a LOT of photographs, overlap, different                                                           heights and angles

 

Software steps

1) Loaded photographs, software calculates camera locations

 

 

 

 

 

2) Generate sparse point cloud

 

3) Generate dense point cloud

 

 4) Create mesh and apply texture

 

 

5) Export and/or Upload

 

 

Download to Unity, etc."

 

• Incorporate Model in Scene
• Mesh Collider (may be many meshes)
• Probably can't Decimate
• Texture is a single .jpg - so decide on 2048 x 2048 or 8192 x 8192 and compress
