Three. js source code annotation (36) Texture/CubeTexture. js I also just started learning. Sorry for the errors in many places. The following code is a comment on the Texture/CubeTexture. JS file in the THREE. js source code file. /*** @ Author mrdoob/http://mrdoob.com/* // The CubeTexture class is used to create a cube composed of a reflection, refraction, or texture Paster object for the surface, here and THREE. the Texture method is different.

36. IO model, 36io Model In particular, this essay is copied to egon (Lin Haifeng ). I. IO model Introduction To better understand the IO model, we need to review in advance: synchronous, asynchronous, blocking, non-blocking What are the differences between synchronous I/O and asynchronous I/O, blocking I/O, and non-blocking I/O? Different people may give different answers to this question. For example, wiki considers asynchronous IO and non-blocking

."Continuation" Design 21.The method above is perfect, the following is an imperfect method, do not use sub-reports. Put the grouping information and the "continuation table" in the group header. Implemented using the Printon property of the control object (above is implemented using the Printon property of the report column band).Sets the Printon of the group and the Printon of the text for the continuation table, respectively.Look at the effect, not very perfect, but also realized.Imperfect pl

effect. The actual template output may be just the current operation, and the front and rear operations generally do not have any output.2. It is important to note that there are some methods in which exit or error output is used, and it is possible that the Post method will not be executed. For example, if the error method of the system action is called in the current operation, then the post operation will no longer be performed, but the post-method execution of the success method is not affe

Java record-36-Bubble SortingBubble Sort is a simple Sorting Algorithm in the computer science field. It repeatedly visits the series to be sorted, compares two elements at a time, and exchanges them if their order is wrong. The work of visiting a sequence is repeated until there is no need for exchange, that is, the sequence has been sorted. The name of this algorithm comes from because the larger element will slowly "float" to the top of the series

database spends a lot of time querying, the script will not stop executing. Subject to availability. 34. Using the extension library Some examples: >>mpdf-can generate PDF documents from HTML >>phpexcel-Reading and writing Excel >>phpmailer-easily handle sending messages that contain nearby >>pchart-using PHP to generate reports Use the open Source library for complex tasks such as generating PDFs, ms-excel files, reports, and more. 35. Using the MVC framework It's ti

to use an MVC framework like CodeIgniter. The MVC framework does not force you to write object-oriented code. They only separate PHP code from HTML. >> clearly distinguishes between PHP and HTML code. There are benefits in team collaboration, and designers and programmers can work at the same time. >> Object-oriented design functions that make it easier for you to maintain >> built-in functions do a lot of work and you don't need to write them repeatedly >> development of large appl
