Maintain a life cycle and the last rendering time for each texture, update the rendering time for each rendering, and traverse the current texture set every certain time (15 seconds) in CCTextureCache, if a texture is not rendered after

First, we will introduce the concept of texture.
Image ---- texture --- memory --- GPU
During the running process, the game should load all the images to be used into the OpenGL ES texture that the GPU can understand and execute. Note that when the image is filled into the texture, its length and width should both be t
OpenGL can specify texture coordinates for vertex in two ways:
1. Assign coordinates to each vertex manually. You can use the gltexcord * () function.
2. OpenGL automatically allocates coordinates for each vertex. This task is completed by the function gltexgen.
At first, I didn't quite understand the gltexgen * () function. I don't know how OpenGL automatically generates texture coordinates. After reading
friends who have tested the ms3d model in irrlicht may find this phenomenon. If the ms3d model has only one texture, the model can be rendered normally, regardless of whether the texture file is placed in the same directory as the demo and the Program or by calling the setmaterialtexture () function, when the model has two or more textures, The pasters and executable programs can be correctly rendered onl
Generally, our render target is post-buffered, but you can also set the render target as a 2D texture, and then display the 2D texture through the texture method, you can display multiple scenes on one screen.
In this tutorial, we use mytutoriald3d11_59 to render the texture.
First, create a rendertextureclass. In this
Introduction to the development framework see: One of Opengl ES NDK Instance development: building a development frameworkThis chapter draws a rotated texture pyramid based on the sixth chapter (six: Texture mapping) of the Opengl ES 1.x NDK instance development, with the same principle as texture mapping, and it is important to note that the vertex arrays and
In DirectX mesh files, a texture may be shared by several materials. This is because vertices are grouped by Attributes. different attributes are required as long as the materials and textures are different. In general modeling software, textures are often used as part of materials. Each "material" has its own texture during export, this is also because sometimes the mesh uses the same
A pattern of textures is formed by listing the patterns of a scene in random fashion across the canvas. And this kind of texture pattern has two kinds of performance, the first kind is the fine texture texture, this kind of texture mostly applies to the background of the webpage, it appears relatively low-key, the main

11. Next, let's take a look at how the surface works. Click on the top level of the layer Order and the dialog on the right becomes the Surface Options dialog box (Figure 12). This layer controls the specific details of the texture, combining the shading layer to control the lighting effect. Its control options have four items, respectively, for roughness--roughness, brilliance--luster, metallicity--metal texture
Advantages of TexturePacke:1. Memory problems. The width and height of OpenGL textures and the memory used will automatically expand to the Npower of 2. For example, 257*257 will be used for 512*512, and mobile phone memory is a rare resource,2. In terms of rendering speed, we should try to reduce the texture switching during rendering. If we do not pack the image, the texture rendering efficiency will be r

Shape path too large to be rendered into a texture (747x8294, max = 8192x8192)
This problem occurs when the image is displayed. It is analyzed that the size of the loaded path is limited because hardware acceleration is enabled.
Scenario:
Select an image from the album or local image and display it in the gridview. You can use similar Image Browsing tools on other pages to view all the displayed images.
When I load all the images on my Image Brow
have a title bar, and there is no smallest/big, close button, however, you can right-click the program button on any service bar, minimize, move, size, and close a lot of options, and the window also responds to these commands. If the ws_ex_toolwindow extension type is added to the window, the program will not appear on the taskbar, which is the same as QQ. However, currently, our program only implements the texture of the title bar, this extension t

Next we will introduce the texture-based feature method, which is well-known for its use of the string-based Image Processing (SLB) and the string-based Image Processing (siltp) features. This article is a texture-based method for
We are still exploring how to use html5 + webGL to implement 3D street view. The topic of this article is how to add multiple textures to a 3D model and why there are multiple textures: because it is a network application, you must consider the network bandwidth issue, if a texture image is directly transmitted from the server to the client without processing, the speed will be very slow. To solve this problem, we must cut a complete

If the ws_ex_toolwindow extension type is added to the window, the program will not appear on the taskbar, which is the same as QQ. However, currently, our program only implements the texture of the title bar, this extension type is not supported for the time being. You can ri
In the following tutorial, some texture materials are used in the cortex. In fact, the PS filter can also be used, which may be a little more complicated. With the leather texture, you can easily make a leather bag. it mainly involves the setting of relief and light and shade, as well as the production of edges. The tutorial may not be very detailed. you need to give full play to it on your own. In the foll
