Dual-barrel telescope

The dual-tube telescope is a useful astronomical observation tool. You can use it to watch a game, concert, or birds in the sky. You can also use it to enjoy the galaxy, the crater on the moon, several satellites around Jupiter and countless stars 2 million light years away. Many people mistakenly think that the dual-tube telescope is not used for astronomical observation. In fact, it is a favorite tool of

Dual-barrel telescope literacy

I have bought several telescopes, but I recently discovered that some basic concepts are not understood. After best practices, I wrote this post, hoping to help cainiao who have the same experience as me. I. Telescope exit pupil diameter and brightness The telescope never saw the nebula. I mistakenly thought that the magnification of the telescope was not enough.

ImageReady Mask Animation: Telescope in the Dark

Believe that the people who have learned flash generally use layer mask to do the telescope effect in the night, Photoshop (imageready) clip mask is like the mask layer in flash, but the mask layer is below. The effect of this tutorial is to use the ImageReady clipping mask. Finish effect: 1. Open the image file to be processed in ImageReady, create a new layer (shortcut key ctrl+shift+n), and then draw two circles on the canvas with the rectan

Today, I was cheated by scammers for 245 yuan. Counterfeit military telescope

I went out for a walk this morning and walked on the sidewalk. A car came over and said hello to me. I glanced at him and asked him if I was interested in good things in the army. Then he took out a telescope and tuned it for me to see. The telescope looks pretty good and it's quite heavy. I didn't see things for the first time, and then I found that the angle was not adjusted correctly, and I didn't take

Summary of several situations of vector vectors in c ++ (vector pointer and pointer vector)

Summary of several situations of vector vectors in c ++ (vector pointer and pointer vector) 1. Standard Library vector type Vector is a set of objects of the same type. Each object has a corresponding integer index value. The standard library will be responsible for managing

C + + vector (vector) use of methods to explain (sequential access vector in a variety of ways) _c language

Vectors are vector types that can hold many types of data, such as several integers, so they are called containers. Vector is an important member of the C + + STL, and you need to include the header file when you use it: Copy Code code as follows: #include Vector initialization: There are five ways to do this, examples are as follows: (1)

In practice, the vector series in c ++ -- vector (unique_ptr () is assigned to vector (unique_ptr ())

In practice, the vector series in c ++ -- vector (unique_ptr () is assigned to vector (unique_ptr ()) Previously, we mentioned that the insert method can be used to copy a vector to the end of another vector. As mentioned in previous blogs, if unique_ptr is placed inside the

In practice, the vector series in c ++ -- vector traversal (stl algorithm, vector iterator (do not judge not equal to end () in the loop), operator [])

In practice, the vector series in c ++ -- vector traversal (stl algorithm, vector iterator (do not judge not equal to end () in the loop), operator []) There are many ways to traverse a vector container. Index traversal: for (i = 0; i Iterator traversal: for (vInt::const_iterator iter = v.begin(); iter != v.end();it

Vector series--vector<unique_ptr<>> assignment to vector<unique_ptr<>> in combat C + +

Previous blogs about vectors you can use the Insert method to copy a vector to the back of another vector.Previous blogs have also talked about the need to transfer ownership if the vector container is placed inside the unique_ptr.Come on, now. 818 HowvectorIf you have a regular vector, we can use insert like this://inserting into a

n-dimensional vector product (generalization of 3-dimensional vector product, vector algorithm)

In three-dimensional space, the product of two vectors (a vector product, an outer product, a product, a multiplication of multiples of two vectors: the inner product, the dot product) represents the torque of two vectors, and the mixed product axb of three vectors C, the area of the parallelepiped that is composed of three vector a,b,c. And the position of a,b,c in the mixed product is interchangeable (thi
