3D scanning is the process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance (e.g. colour). The collected data can then be used to construct digital 3D models.
Collected 3D data is useful for a wide variety of applications. These devices are used extensively by the entertainment industry in the production of movies and video games, including virtual reality. Other common applications of this technology include augmented reality, motion capture, gesture recognition, robotic mapping, industrial design, orthotics and prosthetics, reverse engineering and prototyping artifacts.
As per the assignment brief, I would be doing the 3D scanning of an object with the help of SCANN3D app.

Process:

1. Tools and Softwares Used

1. OnePlus 6T
2. SCANN3D app
3. Context Subject (-)

2. Preparation of 3D Scan Design File

Using Scann3D App, I took multiple images of the table lamp from all the angles carefully and followed the self-explanatory instructions in the Scann3D App to get the final outcome.
I tried with a table lamp at the hostel room, and took about 51 images from different angles but upon further calculation, the 3D Scanned object failed to turn up.

I took another sample object like a remote and took about 40 images. The result this time were quite good, as the object was placed on good contrast background with ambient lighting. The scanned model can be shown as below:

Result:

The assignment has given me relatively good insights on 3D Scanning.
The precautions to be taken care of while undergoing the process are as follow:
1. For scanning, place the object in such a manner that you are able to revolve around the object for a clear scan.
2. Make sure that the lighting is enough for the scan.
3. Choose the subject wisely that has a lot of textures and focus points.
4. Avoid shiny and blend surfaced subjects.
5. Take atleast 25-30 images of the object for a cleaner 3D.
