In 2018 I’ve already described a logotype model creation. Now I have a need to make a SVG image logotype for site icon. Basic parameters Torus is described by two radiuses R and r, where: \[R = 10*r\] Center of the first torus: \[C_1 = (0, 0)\] Center of the second torus: \[C_2 = (-R\frac{\sqrt{3}}{2}, -R\frac{1}{2})\] Hemitoruses are ...

We need compare two methods of map enumeration: via forEach method via entries enumeration Code setup will be: const N = 100000; var m = new Map(); for (var i = 0; i < 10; ++i) m.set(i,i); The first case: var x = 0; m.forEach(function(value){ x += value; }); The second case: var x = 0; for (const [key,value] of m.entries()) { x ...

Making simple math model for ESO rotation Introduction Rotation is sequence of used skills. We are interested in choosing the best skill rotation to achive the maximum damage per second (DPS), and kill target as fast as possible. Thus we take following assumptions: we ignore light attack weaving, since it has no influence on rotation we i... Read more 21 Sep 2022 - 10 minute read
