Vectors are the standard tool for 2D and 3D Mathematical research, and in 3D games vectors are the basis. Therefore, it is very important to master some basic concepts and properties of vectors and common operation methods. In this blog, horse and everyone to review and learn about the Unity3d in the common 3D mathematics knowledge.I. Vector concepts and basic definitions 1, mathematical definitions of vectors

vector Container
Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to the vector as a container because it can contain other objects. All objects in a container must be of the same type.
Before using vectors, you must include the

For the first time, I said a little bit. The basic content of vector knowledge and a bit of usage skills, the simple display of its role in game programming. This time, take full advantage of the nature of the vector to imitate a physical phenomenon.
First, I would like to introduce the two basic but very important techniques that will be used.One, the vector b o
this time we go on to look at the Java data structure vectors (vector) Stack (stack). The first is the vector, vectors (vector) classes are very similar to the traditional array, but the size of the vector can be changed dynamically according to the need. As arrays, the elements of a
Vector containers use dynamic arrays to store and manage objects. Because the array is a random access data structure, elements in the random access vector can be used. It is time-consuming to insert an element in the middle or at the beginning of an array, especially when the array is very large. However, inserting elements at the end of the array is fast.The Class Name of the implementation

Vector is considered to be a container because it can store various types of objects like a container, in short, a vector is a dynamic array that can hold
The vector class implements a dynamic array. and ArrayList and similar, but the two are different:
The vector is accessed synchronously.
Vectors contain a number of traditional methods that do not belong to the set framework.
Vectors are primarily used in cases where the size of an array is not known beforehand, or if only an array of size can be changed.The

The purpose of this article is to introduce std::vector, how to properly use their member functions, and so on. The use of conditional functions and function pointers in iterative algorithms, such as in Remove_if () and For_each (), is also discussed in this paper. By reading this article readers should be a

Use of vector in C ++
Vector is the most common container in STL. It is an ordered container that supports random access. Simply put, vector is a dynamic array that can store any type of data, but the array is a static allocation space. Once the space is allocated, the size cannot be changed, but the vector is dynamica
Use of Vector
The underlying Array Structure of the vector class, which contains components that can be accessed using integer indexes. However, the vector size can be increased or reduced as needed to meet the needs of adding or removing items after the vector is created. Therefore, you do not need to consider whether
1) Quantity: Also called scalar, pure quantity, only the size has no direction, can use a numerical value to determine;2) Vector: Also known as vector, describing this kind of quantity not only needs the size, but also needs to express its direction;3) directed segment: a segment with a certain length and a definite direction;4) geometric vector: short
Reproduced in: http://blog.csdn.net/longshengguoji/article/details/8507394The vector class, known as the vectors class, implements a dynamic array, an array of objects used to change the number of elements. Like arrays, the vector class also represents the position of the element with a subscript starting from 0, but the array is different when the vector object
Adopts parallel processing structures such as advanced control and overlapping operation technology, computing pipeline, and cross-access parallel memory.It plays an important role in improving the computing speed. However, the parallel processing potential cannot be fully utilized during actual operation. Vector operations are suitable for the structural characteristics of assembly line computers.
