This chapter is mainly about deriving Viewmatrix and designing a basic camera function.Note I. Derivation of ViewmatrixKey statement:1. How objects in the world coordinate system are described in the camera coordinate system, equivalent to the object in the world coordinate system with the camera transformation, so that the camera and the world coordinate system coincident.2. Inverse and transpose equivalence of standard orthogonal matricesKnown param

swap by using the fsck command to divide a partition into a swap, and then use the MKSWAP command to format the partition as swap, and then use the Swapon The device file name "to start the swap device. can use Free This memory view command to see if swap is loaded correctly. In addition to building a partition into swap, you can use a large file to construct the swap, which is similar. you can also use Swapoff to release swap files when you use a file to build swap.

I tested VB6 in the dormitory last night to call XMLHTTP for communication. synchronous calling is still very easy, but asynchronous calling is confusing, mainly because XMLHttpRequest. the onreadystatechange attribute is unclear about how to use it. It is easy to directly use the callback function in Javascript, but it is very confusing in VB.

load them into an MDI application. To make them available, compile them as class libraries, and then add references to them in the configuration file. Dynamically loading other types of classes This technique can be used in addition to forms for other types of classes. However, the situation is relatively complex. In the previous example, the System.Windows.Forms.Form class interface was able to be bound early because we knew it was a form. Therefore, you can use the method of the form (for ex
