,glRotateAndglScale. OpenGL ES 2.0 does not have the above functions or projection functions, because the fixed function pipeline is replaced by the coloring program module. For OpenGL ES 2.0, standard and projection calculations should be performed in the vertex shader.
In addition, the coloring language for OpenGL ES 2.0 (glsl es) is also a subset of the desktop OpenGL 2.0 (GLSL) Coloring language. The main difference is that GLSL has built-in varia
Recently, I will slow down to update my blog. The key is that many things have not been completed. Sometimes the program has come out, but I still don't know much about it. It's a bit dumb at first. This application is available inWonderfl has read it, but it has been hard to understand this program. Today I learned it step by step. Obtain the pixels of the image and combine these pixels into the above patt
First, we recommend a book: The English version of opencv 2 computer vision application programming Cookbook can be downloaded from the Internet. It seems that there is no translation. This book is characterized by the fact that the program in it is not a process-oriented small program written to demonstrate function functions, but a large
provides the driver independence between the process of getting data as required by Vs and vs itself.
2,Geometric coloring machine (GS)-- Read the elements from the vs ring cache and write one or more elements for each input element as output to the GS ring cache. This program type is optional; when active, it requires a DMA copy (DC) program to be active. GS re
instruction to promote the condition branch. This status continues only for one ALU clause.
Pixel status-- No; no; 1; 192 (64*2-bit ??? :)); The status bit reflects the activity status of each pixel when the condition command is executed. The status can beActivity,Inactive Branch, OrInactive termination.
Effective mask-- No; no; 1; 64; a mask that indicates wh
Procedures A stored procedure is a set of precompiled SQL statements stored on a server, similar to a batch file in a DOS system. The stored procedure has the function of immediate access to the database, and the information processing is very rapid. By using stored procedures, you can avoid multiple compilations of commands, which reside in the cache after a single execution, and need to call only the binary code in the cache at a later time. In addition, the stored procedure runs on the serve
), and you can secretly build another screen from lines 400 to lines 799. When the build ends, set yoffset to 400, and the new screen will be displayed immediately. Now we will start to build the data for the next screen in the first memory area. This is very useful in animation.Another application is used to smoothly scroll the entire screen. Just as on the front screen, allocate 800 rows of space in the memory. Set a timer every 10 milliseconds. For more information, see man settimer and man.S
stored proceduresStored procedures are a set of pre-compiled SQL statements stored on the server, similar to the batch processing files in the DOS system. Stored Procedures provide the ability to access databases immediately and process information quickly. Using the stored procedure can avoid multiple compilation of commands. After one execution, the execution plan will reside in the cache. In the future, you only need to directly call the binary code in the cache. In addition, the stored proc
Based on the Zhang Zhengyu calibration method of the Opencv3.1 calibration program, first use Findchessboard to find the board, with Cornersubpix sub-pixel positioning, and then use Calibratecamera to the calibration, and finally the calibration results stored in the XML fileThe program is based on vs2013 and opencv3.1, to note that there are 3.1 before 2XX serie
