By means of this article, I want to share my experience in using computer geometry, which I have accumulated in the process of working on my dissertation. Not everyone knows Qt Creator contains tools for working with geometry (in particular QVector3D), for which there is no detailed manual in Russian. Therefore, here I will try to summarize the necessary theory and its implementation as briefly as possible.

Generating random numbers may be needed, for example, to calculate weapon damage in a computer game or to represent a graph from random numbers.

Qt provides the qrand function for generating random numbers, and also, starting with Qt 5.10 , the QRandomGenerator class.

Let's see how random values can be obtained in Qt, and how random they are.
