Currently, the two mainstreamGraphics cardThe manufacturers are ATI and nvdia, and their graphics cards have their own unique characteristics. However, the functions and usage of the two brands of graphics cards are completely different. Nvdia video cards focus on the game picture and picture quality. ATI graphics card

The device is usually programmed by means of a read-write device register, which is programmed on the X86 system by a dedicated IO instruction, and on other systems such as MIPS, SPARC, by mapping the device's registers to the memory address space directly using read-write memory to program the device.Radeon graphics card provides two ways to program the hardware, a "push mode" is called the direct write register, the other is called pull mode, this b

The above section Code It is designed to call bitmap from a resource, but you can easily modify it to call bitmap from an external file, then try to call bitmap from an external file. For external calls, remember to add the lr_loadfromfile flag

PerformanceRunning Putimagedata () is slower than DrawImage () and takes precedence over DrawImage () under the same conditionsManipulating the image data requires traversing a large amount of data, which should be noted:1) Avoid direct access to

In general, the basic framework for game development typically includes the following modules:Window Management: This module is responsible for creating, running, pausing, and resuming the game interface on the Android platform.Input module: This module is closely related to the Windows Management module, which is used to monitor user input (such as touch events, key events, accelerometer events, etc.).File

Paths and sub-pathsAt some point, there can only be one path in the canvas, and the canvas specification is called the current path, which can contain many sub-paths (subpath), and the subpath is made up of two or more points.Context.beginpath

The canvas element can be said to be the most powerful one in the HTML5 element, and its true ability is expressed through the context object of the canvas (drawing contexts).The Filltext () method uses the FillStyle property to populate the

written cp_int_stat register.In the Radeon driver code, the Radeon_fence_emit function (referred to as the code in the GPU Command Pack chapter) is called after completion of filling the drawing command into the ring buffer, and the R600_fence_ring_emit function is eventually called on the R600 graphics card. The function has the following code:2327 void R600_fence_ring_emit (struct radeon_device *rdev,2328 struct radeon_fence *fence)......2347/* Emi
