best eyepiece for planets

A ship wants to pass through an area with an minor planet. Then, he needs to use a gun to kill all the planets so that the ship can pass safely. This gun can take a line at a time by comparing Nb, or a column. Then a matrix is given and the coordinates of the planet in this matrix are given. Then, how many shots do you need to launch when your ship passes through this area? (All the minor planets must be ki

number of imageviews, and then using Animation or Animator for each ImageView for the corresponding moving effect; 2. Use your own Rendering Method for implementation. Isn't it just a floating planet; Needless to say, the second solution above is certainly more desirable. The first solution has the following defects: 1. Too many views are created, resulting in poor performance; 2. Poor flexibility. For example, it is troublesome for UE or products to increase or decrease the number of

The "Mars Rescue" craze has not faded, and the Star Wars 7 is about to be released soon. In fact, even without these films, everyone's enthusiasm for the universe has never been lowered. Human beings like to look up at the sky since ancient times, which also explains why we are so obsessed with the universe, planets, stars, black holes, galaxies, aliens, astronauts, satellites and so on, they always attract our attention.

We all know that the universe is big and big, but how big it is, I'm afraid most people don't have a clear idea. In fact, even the tiny solar system that we are in, its sheer size is enough to make people mad. Liu Cixin's science fiction "three-body 2: The Dark Forest" has a scenario in which the first military officers of China's air force almost collapsed in the face of a true proportion of the solar system's map. This page shows the vastness of the solar system in a true and precise pro

Thinking of solving problems Because 137 and 73 are prime numbers, so the least common multiple is 10001, the problem is converted to a high-precision number of 10001 to take the

Multi-Instance renderingOpenGL's multi-instance rendering is a way to execute multiple identical render commands consecutively, and each command produces a slightly different result, often used to render a large number of geometric objects.Imagine a scene, such as space, where we need to render several marts planets, and if we use the conventional approach, the rendering process should be: Draw the first planet Glbindvertexarray--gldrawarrays or Gldra
