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
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

How to set up the NVIDIA graphics card
1. Right click on the desktop to select Nvidia control Panel;
2. "3D setting"---"To adjust the image settings by previewing"---"Use my preferences, focusing on"---"Performance---" Application ";
3. If the game still feels there will be cotton can choose to "Manage 3d settings"-"Maximum number of pre-render frames";

1, this time we draw a smaller figure, convenient for us to explain the bulk copy method.
2, after a good copy of a rectangle, is not every time to hold down the "alt" key, and then move with the mouse, a copy? That's too much trouble. After we copy the first one, you can press the CTRL key and the "D" key to quickly copy the second
3, repeatedly hold down the "CTRL" Key Plus "D" key, you can quickly copy many, forming a row of small rectangles
4, and then use the "selection Tool", all
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

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,
