Africa, the second-largest continent after Eurasia, is washed by the Mediterranean Sea to the north, the Red Sea to the northeast, the Atlantic Ocean to the west and the Indian Ocean to the east, and both oceans to the south, separated by 20 degrees east longitude.
Africa also refers to the part of the world consisting of the continent Africa and the adjacent islands. The area of Africa without islands is 29.2 million km², and with islands – about 30.3 million km², thus covering 6% of the total surface area of the Earth and 20.4% of the land surface. There are 55 states (including dependent territories) on the territory of Africa. Its population is 1.38 billion (9 September 2021). (9 September 2021) (18.2% of the world’s population).
The length of the African continent from north to south is 8 thousand km, from west to east in the northern part – 7.5 thousand km.
What can I use a 3D model in STL format for?
STL model of Africa can be used for various purposes:
- Making physical models from plastic or photopolymer using 3D printers
- Making models of wood or metal using CNC machines
- Making a high-resolution relief using 3D laser markers
- Making of “master forms” for duplication of products using foam polystyrene or concrete
- Creating computer graphics
- Creation of low-polygonal models for computer games
What is the resolution of the 3D model of Africa?
With the development of technology, it is becoming possible to produce more and more precise relief models.
For example, there are 3D printers that can print models with a layer height of 0.16 mm, 0.1 mm, 0.05 mm, or even less. These devices require high-quality models. But a higher-quality 3D model contains more polygons and has a larger file size. One of the challenges is to find a compromise between the file size of the STL model, which would be convenient to work with, and the desired quality of the finished product.
The 3D model of Africa has a fairly large size and many polygons.
How do I change the parameters of the STL model of Africa?
You can easily resize the model in any program that allows you to import STL files.
In addition to changing the scale in width, length, and height, you can add a higher base. You can also use anti-aliasing tools, add bulk text, reduce the number of polygons, etc.
