I had a look at this guide on 3D scanning objects and gave it a try.
The guide describes how to take pictures with a normal camera and make a 3D representation of it. For the mesh to be decent, you must take a lot of pictures. In my test, I took 21 photos. Covering as many angles as possible. The lighting must be consistent in all images. So I had to be quick in taking the pictures outside, while the sun was behind clouds.
I used my Canon D500 set on manual mode. With ISO 100 and a shutter speed of 1/100.
The scene in the photograph is 3D scanning friendly. There's no reflective surfaces. No semi transparent objects, like leaves.
In the guide they use the open source program Meshroom. I installed the program on my gaming PC, which has a beefy graphics card. The program utilized GPU acceleration when processing the scene. First I tried running on my laptop. But I had to cancel the processing, because it took too long.
After importing the images into Meshroom, I just ran it with the default settings enabled. Ca 5 minutes later, the scene had been constructed from the images:
To use this mesh in a real-time graphics situation, the amount of vertices should be cut down:
