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
I see a lot of friends on the internet asked "How to switch Dual graphics card", the following small set up in the WIN8 system Intel platform +AMD graphics card switching methods and settings, Nvidia's method is similar, a total of three ways to set up, should be relatively complete.
Method One
1. Right click on the desktop, choose to configure the swap display card;
2. Open to configure the
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,
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
