In the image Color format support, H.264/AVC the first version of the standard only support YCRCB 4:2:0 sampling method, and in the second edition of the revised standard to add 4:2:2 and 4:4:4 sampling format, usually these formats will be used in digital movies or HDTV films.3.1 H.264/AVC image Format class structureH.264/AVC hierarchy from small to large in sequence is Sub-block, block, macroblock, Slice, slicegroup, frame/fiel

Class canimmesh is the most critical class. All the implementation details related to the skeleton animation are encapsulated in this class. This class also defines an object m_alloc_hierarchy of the class callocatehierarchy, this object loads the skeleton hierarchy, animation data, and other geometric data of the animation mesh model from the file. The canimmesh class is defined as follows: class cAnimMesh{private:cAllocateHierarchy*m_alloc_hierarch

regarded as a low frequency component on the fine mesh, and can be a high frequency component on the coarse mesh. As a fast calculation method, The multigrid method iteratively solves the algebraic equations composed of partial differential equations after discretization, the basic principle is that a certain grid is the easiest way to eliminate the error components corresponding to the wavelength and th

51517860Many times we need to combine material balls with the same shader to reduce the drawcall. For example, in the Kowloon War, a character with 10 parts, 10 parts of each from different FBX files, plus the body, there are 11 of material balls, accounting for 11 drawcall. If there are 10 characters running in the main city, the light figure takes up 110 drawcall! So the material ball merging is necessary at this time.(Multi-part facelift effect in Kowloon War)Material ball Merge, divided the

, triangle slice reduction can reduce the number of triangles in the mesh division process. Reducing the number of triangles facilitates file operations. L there are two ways to generate a 3D grid through interpolation of the image: Gray interpolation and contour interpolation. contour interpolation is 2D interpolation in the image plane, so that these images can be expanded in height. Gray interpolation is a real 3D interpolation. When the image disp

In this article, we will study the progressive grid together, and we will not talk much about nonsense. The topic is as follows: 1. Concept of gradient Mesh Incremental mesh is implemented through the id3dxpmesh interface. this allows us to simplify our

different assets, such as models, textures, effects, and it isComposed of writable layers, where the four most important are: importers (convertThe original file format to a default DOM), processors (process the asset in anyWay you like), compilers (generate a managed binary object that is stored) andLoader (load the managed binary at runtime ).

Android suction animation effect detailed. Here, I want to introduce how to achieve a similar effect on Android. First look at the effect I realized. The above illustration shows a few frames of the animation, from 1-4, which shows the picture being inhaled from the original graphic to a point (red logo). To achieve this effect, we took advantage of the Canvas.drawbitmapmesh () method, which involves the concept of a mesh. The concept of 2,

8 triangular faces (the number of triangular polygons for the entire mesh surface can be determined based on the number of two dynamic points). Finally, we fill the 8 triangles with the same color, and we can achieve a complete stereoscopic mesh surface. The principle is very simple, that is, I believe you can see here that everyone understands, and then we learn how to use the code to implement it. First

The scope discussed in this paper does not include geometry reconstruction, texture reconstruction, but only three-dimensional measurement algorithm based on the existing three-dimensional triangular mesh model (the human triangular grid). In fact, the circumference measurement is a three-dimensional model with a specific plane intersection, and the intersection further analysis of the intersection of the specific closed part (if there are multiple cl

Please look at the original post, step: Unity3d Collision detection with the difference between the collider and the triggerTo create a collision you must add a rigid body (rigidbody) and a collider to the game object, which allows the body to move under physical influence. A collision body is a class of physical components that are added to a game object with a rigid body to trigger collisions. If two rigid bodies collide with each other, the physical engine calculates collisions unless two obj

Mesh (Z) statementMesh (z) statement can give the matrix z element of the three-dimensional blanking graph, the network surface is defined by the z-coordinate point, and the preceding x-y plane of the same line, the graph is connected by the adjacent points. It can be used to display large matrices with large amounts of data that are difficult to output in other ways, as well as to draw a z-variable function. The function z=f (x, y) of the two vari
