A graphics subsystem having a programmable shader controllable by both state-based control information, such as DirectX 8 control information, and program instructions, such as DirectX 9 shader program instructions. The programmable shader translates state-based control information received from a host computer into native control information. The programmable shader translates into native control information program instructions fetched from memory locations identified by a received memory reference and program instructions received from the graphics subsystem. Native control information configures computation units of the programmable shader. The programmable shader optimizes the generated native control information by combining certain operations. The graphics subsystem detects memory references sent from the host computer and pre-fetches program instructions for transmission to the programmable shader. Native control information from multiple control sources is concurrently used in the programmable shader.

The invention provides a spherical display image processing method and system, and the method comprises the steps: enabling a to-be-displayed image to serve as a texture map and to be pasted on a model or a curved surface, and rendering the model or curved surface till a cubic texture or directly carrying out rendering; building a target image of a plane for spherical display according to the cubic texture, wherein the corresponding relation between the target image and the cubic texture is that the target image is located in a polar coordinate system and the pixel coordinates corresponding to each pixel of the target image are expressed through polar coordinates; enabling the polar coordinates of each pixel to be correspondingly converted into a three-dimensional coordinate point on the a spherical surface in a three-dimensional coordinate system, and enabling the color value, obtained through the sampling of the cubic texture at each three-dimensional coordinate point, of each point to be given to a corresponding pixel of the target image; carrying out the algorithm transformation in an actual implementation process with the help of a top point shader of a graphic platform directx or opengl, and achieving the high-efficiency and high-quality conversion output through a graphic display card, thereby enabling display to have no blind region, enabling display to be flexible, and enabling the operation efficiency to be high.

A direct access driver solves limitations of DirectX operation under the Microsoft architecture when using multiple monitors. The direct access driver allows applications employing DirectX application program interfaces to use hardware acceleration without display errors on the monitors. Display errors can occur if multiple frame buffer addresses are returned in response to “GetFrameBufferAddress” DirectX calls. A single address is returned for two or more frame buffers on a display driver card by performing, without the DirectX application's knowledge, background operations that track hardware acceleration demands from two or more graphic user interfaces and frame buffers. The background operations entail constantly changing the frame buffer pointers relative to the location of offscreen DirectX application data, while one or more DirectX applications are moved in the display space from monitor to monitor.

The invention provides a Web-end three-dimensional GIS (geographic information system) software design method with geographic spatial data confidentiality. The method comprises the following steps that: a client applies for server resources from a three-dimensional GIS cloud service resource scheduling center, and the resource scheduling center allocates idle servers to the client; the client sideresponds to mouse and keyboard operation of the user and encodes the corresponding operation message to obtain an encoded control flow message, and then the encoded control flow message is sent to the server side; the server decodes the received encoded control flow message; the method comprises the following steps: receiving space data, decoding the space data, executing a corresponding functionaccording to operation information of a mouse and a keyboard obtained after decoding, rendering a three-dimensional scene corresponding to the space data into a two-dimensional image, converting thetwo-dimensional image into a corresponding video stream, and sending the video stream to a client to prevent data leakage caused by sending real space three-dimensional data to the client; the serverside is provided with an image buffer area compatible with the OpenGL and the Directx. The method has the advantages that data leakage is effectively avoided, and graphics card resources are reasonably utilized.

The invention is applicable to the technical field of computers, and provides an interface rendering method and terminal equipment. A first request message is sent to a server according to an instruction input by a user, so that a first hypertext markup language (HTML) file returned by the server based on the first request message is received; a DirectX interface is called; the first HTML file isrendered to display a starting interface of an application program; a second request message is sent to the server according to a JS file in the first HTML file, so that an encryption file returned bythe server based on the second request message is received; the encryption file is decrypted to generate a second HTML file; and the second HTML file is rendered to display contents except the starting interface of the application program, so that the rendering efficiency and the rendering effect are improved, and the time of white screen is shortened.

Disclosed is a method for capturing a directX moving picture. The method consists of (a) allowing the control unit to generate a multisampled rendertarget surface of a moving picture using an anti-aliasing technique for a capturing target moving picture of the directX multimedia contents in a buffer; (b) allowing the control unit to detect the capturing target moving picture using the anti-aliasing technique, which is provided in a back-buffer by executing the directX multimedia contents and copy and temporarily store the detected capturing target moving picture to and in the multisampled rendertarget surface; (c) allowing the control unit to output the temporarily stored capturing target moving picture on the basis of an FIFO method when the capturing target moving picture is stored in the multisampled rendertarget surface at a reference value or higher; and (d) allowing the control unit to convert and store the output capturing target moving picture.

The invention provides a method for image processing with the following steps of replacing a DLL file of a system video driver and a delineation driver interface (DDI) defined in the file with the pre-structured DLL file of a screen-grasping shell and a delineation driver interface (DDI) defined in the screen-grasping shell, obtaining the corresponding parameters of the system surface and settinga user-defined mapping surface according to the corresponding parameters of the system surface in the screen-grasping shell, and image-mapping on the user-defined mapping surface via system invoking the DLL of the screen-grasping shell.

The invention provides a method for achieving real-time mutual embedding of a two-dimensional scene and a three-dimensional scene. The method comprises the steps that a shared display control end creates a new thread on a CPU; A new thread creates a new second DirectX rendering module on the GPU; the current video memory data is copied in the video memory; After being compressed, the data is sentto the shared display control end through a network; And the shared display and control end renders the M-dimensional scene frame, so that the M-dimensional scene frame rendered by the shared displayand control end is embedded into the N-dimensional scene rendered by the shared display and control end. The method has the advantages that the mutual embedding of the two-dimensional scene and the three-dimensional scene can be realized, and the real-time mutual embedding of the two-dimensional scene and the three-dimensional scene can be realized, so that the M-dimensional scene rendered by theshared display and control end is embedded into the N-dimensional scene rendered by the shared display and control end; Moreover, at the shared display control end, native interaction and display canbe directly carried out on the embedded M-dimensional scene, so that various use requirements of people are met.
