First, let we see a infinite sum: S = 1 + 1/2 + 1/4 + 1/8 + 1/16 +... is equal to 2, beacause if we get 2 S = 2 + 1 + 1/2 + 1/4 + 1/8 +... = 2 + S => S = 2. On the other hand, this same reasoning suggests that we ought to define T = 1 + 2 + 4 + 8

Geometric moment was proposed by Hu (visual pattern recognition by moment invariants) in 1962. The F (x, y) (p + q) ry moment is defined as mpq = ∫ (x ^ p) * (y ^ q) f (x, y) dxdy (p, q = ,...... ∞) Moment is used in statistics to reflect the

Garbled characters will appear when you replace an object containing Chinese Characters in ant: This is mainly because ant operationsCompositionWhen using this operation, you can specify the encoding method of the character set: Encoding =

Level 1. Given an explicit object X and an explicit property P (x), prove that p (x) is true. Level 2. Given an explicit set X and an explicit property P (x), prove that p (x) is true for all X in X. Level 3. Given an explicit set X and an

Over the past two years, I have been engaged in some mature commercial engines, and my thoughts have gradually changed. I used to think that the engine code is easy to write. The Code of many commercial engines is a mess ~ Later, I thought engine

We define the greatest common divisor of two integers m and n is the largest integer that divides them both. gcd (m, n) = max {k | K/m and K/n }. One of the nicest properties of the gcd is that it is easy to computer, using a 2300-year-old method

To increase the expressiveness of scenes, adding illumination effects to rendering is essential. First, a certain algorithm is used to generate the illumination rendering effect for the entire scene, and then the illumination rendering effect is

In web-based traditional 3D game engines, I also said that emscripten was not mature enough, but it had made great progress in just a few months, and its availability even exceeded flascc! On gdc2013, unreal released a emscripten-based porting demo.

Ambient occlusion (AO) is a popular method in the field of graphics to obtain more realistic Global Illumination effects. This method is used to determine the AO effect of the current point based on the occlusion information of the ry distribution

The closest point to solving the convex compartment is a very useful Algorithm in several computational ry. It is often used in the graphics-related fields such as Collision Detection and physical engines, in addition, the efficiency of this

I recently read a paper in i3d last year, shadow caster culling for efficient shadow ing. I think it's good. Here is a brief summary. The basic principles of algorithms are easy to understand, as shown in. It can be seen that for camera under a

Moment is an operator used to describe image features. It is used in pattern recognition and image analysis. so far, common moment descriptors can be divided into the following types: geometric moment, orthogonal moment, plural moment and rotating

The mesh refinement of a 3D model is a representation method based on discrete mesh surfaces. It can be used to construct smooth surfaces from any topology mesh. The basic idea of the refinement method is to define the limit of a grid sequence. A

Multi-view display of OpenGL in MFC can be used in many cases, and Its Expressiveness is strong enough. Some time ago, I needed to make a scenario editing tool similar to Max to edit the scenario that I needed in my ongoing FPS game. Because I don't

6. Load camera and light In the fbx model, the common information except geometric data may be camera and light. Although in the game, these two pieces of information are generally not obtained directly from the model, they are provided by the

Using BSP to split indoor scenes in the game is a traditional but effective method. The quality of BSP creation determines the robustness of BSP during use, because BSP will be used for rendering and physical interaction. The process of creating a
