IntroductionIn the previous section, I described how to implement a ray-to-triangle cross-detection algorithm. However, we should know that in game development, a model has a lot of triangles, if you want to all objects, all the triangles to do this detection, even if the current computer computing ability, is not efficient to complete. Therefore, we need to use other means to remove some of the objects that are not likely to cross, this early thinking, a lot of use in 3D game technology. In thi
?? Recently, when solving three-dimensional problems, it is necessary to judge whether the segment crosses the cube, and the question can be extended as follows: whether the ray passes through the cube aabb.?? The commonly used algorithm for collision detection in 3D game development is the axis-aligned rectangular bounding box (axially Aligned bounding box, AABB) box method, the basic idea is to use a cube

1. 3D pickup Technology
In 3D games, users can select certain objects in the 3D world for operations such as drag and drop, in this case, the program needs to convert the point coordinate on the two-dimensional sc
equivalent to the two overlapping boxes which are first traversed in front of the container, which is the equivalent of touching the one. Leave the above issues behind, back to figure 1-1. As shown in Figure 1-1, the final thing to do is to find the intersection of the Ray and the near plane and the far plane according to the touch point on the screen, so that we can get the ray we need. In Cocos2d-x 3.3beta0, Ray represents the Ray class, which contains the starting point and the direction
Tag: enumeration operation break maximum result. com Floor Understanding Continue Title Description : output all the 4 -bit full squares (i.e., the first two digits equal to the AABB The latter two digits are also equal). The features are powerful when branching and looping together: Below is a list of all possible results aabb, and then determine if they are full squares. Note that the range of a is
"The culmination of a fast-changing AABB "When changing a AABB, you can quickly calculate the aabb of the vertex after the change. When there is a rotation, the AABB may be larger depending on the 8 vertices. The eight vertices of the aabb need to be transformed as follows:
Any real-time 3D InteractionProgramIf there is no collision detection, it is of no value or even unusable. The most common Collision Detection Technology in the game is bounding volume collision detection. For games running at 60pfs, it takes only about 0.0167s to process each frame of data. For different games, collision detection takes about 10-seconds ~ 30% of the time, that is, all collision detection must be between 0.002 and ~ Within s, it was a huge challenge. Therefore, any box should me
1) AABB bounding box: AABB bounding box is aligned with the axis of the bounding box, the simplicity of good, poor tightness (especially in the diagonal direction of the elongated shape of the object, the use of AABB, will leave a very large corner gap, resulting in a large number of not required bounding box intersection test). When the object rotates, the
Beautiful number detection: The main can detect the connection number (positive connection 12345, 65432), AABB number, mobile phone number, date number (birthday, annual), Abbcabb, 3 more than repeat number. More type number detection can be modified according to the following expression.1.

Example 2-1 AABB
Output all the four-digit full records in the form of AABB (that is, the first two digits are equal, and the last two digits are also equal)
#include Conclusion: one group of Reverse Thinking solves the same problem
2. Use the variable n = A * 1100 + B * 11 to store four digits.

Stop JOB: broken
First pass
Select * from user_jobs;
Find the job id, and then call
