To improve browsing performance, ArcGIS Server is usually used for map caching (commonly referred to as "tile technology "). For example, mapabc and GoogleMap currently use this technology.The so-called map cache technology refers to cutting a map into images of certain specifications and saving it to a computer hard disk according to certain mathematical rules. When a user accesses the map service through a client browser, the server directly returns

In openlayers learning-layer system (1), draw the entire openlayers UML architecture diagram.
Here we will focus on the process of drawing the network tile map of openlayers. Here we will use the XYZ layer as an example for debugging and learning.
Before the discussion, we should first clarify some basic concepts:

Aesthetics is essential in mobile applications and is synonymous with intuitive operation. In Windows Phone, the visual elements of your tiles, splash screens, icons, controls, and navigation cause users to be aware of the tasks, priorities, or actions within the application, and to display information in a novel and compelling way. Your app will require a custom design of live tiles, animated icons, and splash screen images (to introduce the app to users when they load the app). These designs a

. Another disadvantage of IMR is that its render commands are required to read and write frame buffer,depth buffer and stencil buffer at any time, which leads to a large amount of memory bandwidth consumption, which is the most consumed and time-consuming operation for accessing the external memory on the mobile platform.Therefore, in the field of desktop GPU, TBR save bandwidth and low performance is not in line with the requirements of PC, IMR Unified Lake. But in the mobile GPU field, TBR low
Original: Windows 8.1 app re-start-tile updateThis article together with you to learn about the update of tiles in Windows 8.1, we look at how to use it to make a better app tile.First, let's compare the tiles in Windows 8 and Windows 8.1 in the form of presentation:Windows 8 supports two sizes of tiles, square tiles (150 * 150 pixels) and rectangular tiles (310 * 150 pixels). For example, messages and calendars belong to a rectangular
Coordinate System and map image encoding]
To optimize the map system performance and increase the speed of map download and display, all maps are divided into small square blocks of 256x256 pixels. Because the number of pixels varies at each zoom level, the number of Map Images (tile) is also different:
map width = map height = 2^Leveltiles
Each tile has an XY coordinate value from (0, 0) in the upper left

Brief introduction
Magnets are an important element in the application of the user experience in the Windows application store. When an application is installed, its tiles will be created at the Windows 8 Start screen. The tile (called the primary tile) is used as a shortcut to start the application. By default, the primary

Shared memory (SMEM) is an important component of GPU. Physically, each SM contains a low-latency memory pool shared by all threads in the currently executed block. SMEM enables the threads in the same block to cooperate with each other, Reuse on-chip data, and significantly reduce the global memory bandwidth required by the kernel. Because the APP can directly and explicitly operate SMEM content, it is also called programmable cache.
Because shared memory and L1 are closer to SM than L2 and g
The path to cocos2d-x ~ Make the first text game (1), use the cocos2d-x to display the main interface, each level provides the initial phrase TileView, and the target phrase TargetView. The basic concepts and usage of cocos2d-x are introduced. This blog will basically implement the game logic and complete the main part of the game. Follow these steps:
