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

Although little is known, the spring snow lowbrow of "GPU programming and CG programming" really took me into the shader door, where I first clearly understood the meaning of "semantics", and thank you very much.Introductory shader, I think you can read 3 books: "GPU Programming and CG programming Spring snow lowbrow" = "CG Tutorial" = "Real-time Rendering 3rd" (in Reading, recently busy, laid aside), lay a

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

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

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

Vector series in practice c ++-sort the vector using the sort algorithm (sort the vector (string) and use stable sorting std: stable_sort ()) After writing a lot of vector operations, we encountered the Sorting Problem of the vector in our work. Here we will discuss it. Use

In practice, the vector series in c ++ -- creating vector of local structure AND vector of structs initialization I have never used it beforeVector Now, write a short code: #include #include int main() { struct st { int a; }; std::vector v; v.resize(4); for (std::

I've never used it before.vector#include #include intMain () {structSt {intA };STD:: vectorV V.resize (4); for(STD:: vector:: Size_type i =0; I operator[] (i). A = i +1;//v[i].a = i+1;} for(inti =0; I STD::coutSTD:: Endl; }}Compile successfully with VS2015, run result:1234However, this is only allowed after c++11, the compiler does not allow you to write such a syntax, the vector container is not allowed to

C ++ copies the content in a vector to the end of another vector and ends with the vector. When using the vector container, We need to copy the content of a vector to the end of another vector. How can this problem be achieved?

After reading the article, I also started my own work. Hey hey, I didn't expect it to be done. Unfortunately, it's not very good, but it's still worth reading ...... Snow, we may be very familiar with our friends in the north. Friends in the South must have watched TV and so on. Hey hey, it's pretty big when it's snowing, I haven't carefully looked at the snow yet, =. =, Please do not laugh! Now, let's get

Output If all of the snowflakes are distinct, your program shocould print the message:No two snowflakes are alike.If there is a pair of possibly identical snow akes, your program shocould print the message:Twin snowflakes found.

IAfter many years, when the bell stood in front of a wide floor-to-ceiling window and bathed in the warm winter sun, he looked at the chunking children and the flying birds on the school pasture in front of the building, when I remembered the heavy snow, it seemed like a dream. Is there such a heavy snow? Have you ever had such an encounter and clutch? If it is a dream, why is the scar on your knees so eye-

The first step is to draw snow 1> Painting SnowThe snow is white, so you want to draw a white snow in the scene, as for the shape of the snow, it is not good description, everyone according to their own preferences to draw, like my art is not good, draw a rough point of the circle on it, of course, you can also draw i

[Abstract] in the event of continuous blizzard Frozen After the disaster, there was a suspected pollution of drinking water source caused by chlorine salt and snow melt in Guangdong. The "sequelae" of heavy snow also plague Nanjing. Due to the melting of ice and snow, rolling of vehicles and machinery, the Yangtze River Bridge that has just been repaired has o

For the snow scene we may be unfamiliar, we still use VB to make a scene of snow it. In fact, the production of such a snow scene is not complicated, it is the principle of the first in the background of the black screen randomly draw a lot of white spots (snowflakes), and then make these snowflakes continue to move downward (redraw), repeated cycle, the successf

As a three-dimensional Earth, the effect of rain and snow in the scene seems to increase the sense of reality. The demo on the cesium official website contains weather system instances, which are made by the particle system in cesium. As shown in the effect, the essence of the particle system is to add a lot of objects to the scene and use the billboard technology to present them. This implementation method is troublesome when the angle of view change
