To talk about coordinate system transformation, what is the coordinate system? In order: Object coordinate system, world coordinate system, camera coordinate system, projection coordinate system and screen coordinate system. What I'm going to talk about is the transformation between these coordinate systems. These coordinate systems do not come out of thin air, and they are all designed to accomplish the most fundamental goal of co
Operation Steps:
Applicable graphics: Nvidia dual graphics machine
Applicable system: Windows 7
The first video card hardware switch machine, please refer to the manual, to determine the card switch in the open position, and the correct installation of the video card driver, see the following Turielle switch dual graphics function:
Special NOTE: If the switch
We have released a number of two-dimensional curve graphs. In fact, all two-dimensional graphs can be converted into three-dimensional images by adding one dimension value. the content of this section is to post a two-dimensional curve to a sphere to generate a three-dimensional curve.
The following formula is used to generate the value of the third dimension:
Y = SQRT (A * A-x * X-z * z)
Here is an example of a two-dimensional curve:Mathematical graphics
In May January, I installed Windows 7 Beta on my laptop (integrated with Intel 965 graphics card), but I found a very serious problem. In some real interfaces, A video card driver error occurs. Once an error occurs, aero will become invalid, but Windows 7 will immediately be able to recover the driver. This problem has actually been encountered in Vista, but with the official HP driver installed, there is no problem. Unfortunately, the official driver

1 Low-level coloring language TgsiThe OpenGL program uses the GLSL language to program the programmable graphics processor, the GLSL language (the following high-level coloring language refers to GLSL) is a high-level language of syntax similar to C, in the GLSL specification, GLSL language is first translated into the teaching of low-level class assembly language, and then translated into a hardware-specific instruction set. The OpenGL System Managem
1. IntroductionGUI graphic screen is a "graphic LCD Controller + TFT LCD Screen" LCD module, can be used as a third-party graphics library Emwin/ucgui, Microchip-gui, EGUI, Stellarisware-grlib, Microwindows, UGFX and so on graphic display device, GUI graphic screen and traditional TFT LCD screen The biggest difference is that it has 2D graphics acceleration function as well as the font and picture can be st
Recently study Ros operating system, need to use Ubuntu as the basis, so installed a, used to do the development has been used in CentOS, with Ubuntu some not used to. Because the Ros simulator needs to use the 3D simulation, so installed ubuntu12.04 after a look at the video card to identify the No, the results are very sad to find that the graphics drive is unknown. It seems that Ubuntu support for my dual graph

Every time you install a computer, you need to install a graphics driver, but many beginners do not know how to find and install the driver, in fact, we can use to drive life to install updates, and then take a look at it!
What happens if you don't update or even install a video driver?
Graphics drivers if not installed, Windows system color display will be very poor and bad. Because Win7 integrates a lar
DIRECTX12 is a major upgrade to the WIN10 system, but its hardware needs have been upgraded, and not all graphics cards can support the latest DX12. So, what are the graphics cards supported by dx12? This article computer Pepsi Small series for you to summarize the NVIDIA, AMD, Intel graphics support DX12 model list.
Although a number of
1, we first find the "computer" on the desktop and then right-click it pop-up menu Device Manager-Display adapter Click "Update Driver Software";
2, then our computer will automatically scan all updatable or problematic drivers, such as will display "automatic search updated driver software";
Okay, if you have a problem, it will be automatically updated, if you update the graphics driver in this way or no problem,
1. Paint (Graphics g)In Java drawing, the most common use is paint (Graphics g) {... Content... } method to get the brush, and then use containers such as jpanel as the canvas, the content is rendered within the jframe, in many cases this approach is still very useful, the following example:ImportJava.awt.Color; ImportJava.awt.Graphics; ImportJavax.swing.JFrame; ImportJavax.swing.JPanel; Public classTest//
