Photo Scanning

Hey Fellas!

I have been doing some experiments with the software Photoscan. What it does is that it performs a photogrammetric processing of digital images and generates 3D spatial data. I find it pretty amazing and this is a test I did with an object:

What I basically had to do is:

  1. I took a bunch of pictures (high resolution) from every angle(360 degrees) of my object – a unicorn piñata head . Then I uploaded it to Photoscan and chose the option align photos. Once the photos were aligned, I had this:

2) Delete the extra points that I did not need:

3: Built a dense cloud:

As you can see, in this part of the process, the dots are connected, forming a more uniform shape.

Then, from the dense cloud, I have built a mesh:

Finally, after I had the mesh, it was time to add the texture to my model:

After that I exported my model as a .fbx file. When you export your file you will have a .fbx and a jpeg file.The jpeg works as a top-coat of color (texture) that you put on top of your 3D model in other softwares, such as Unity.
