Local coordinates and world coordinates The local coordinate is a relative coordinate, which is relative to the parent node or the relative position of a node you specify. The origin of the local coordinate is in the lower left corner of the reference node. The world coordinate is an absolute coordinate. It is based on the coordinate origin in

matrix creates a transformation of the object to be presented from a special perspective. Projection and photography views in OpenGL ES 1.0 In es 1.0 API, you need to create projection and photo views respectively and add them to the OpenGL environment. 1. Projection Matrix ---To recalculate the coordinates of graphic objects so that they can be drawn at the correct ratio, you need to create a projection matrix using the geometric shape of the device screen. The following sample code demonstrat

I installed the software in the Linux system:/lib/ld-linux.so.2:bad ELF interpreter How to solve, here I analyze there are two, one is commonly used installation because of the system software bit problems, such as: 64-bit system installed 32-bit programs, The other is that cross-compiling does not have that file or directory, so let's look at how to solve the problem.Problem one, 32-bit program resolution is installed on 64-bit systemsis because a 32-bit program is installed in a 64-bit systemW

After reading Metal's development documentation, in addition to some of the official claims for benefits (such as easier to understand and use the API, more direct and granular hardware control, less CPU overhead in GPU usage, etc.), some of the following are more exciting from my limited GLES development experience.More convenient and friendly multi-threaded GPU rendering supportGLES's design, everything must be bound to a GL context, driven by the s

It is very simple to construct an OpenGL view on the andorid platform. There are two main tasks: Glsurfaceview The OpenGL es api provided by the Android platform is mainly defined in the package android. openGL, javax. microedition. khronos. EGL, javax. microedition. khronos. opengles, Java. among several packages such as NiO, glsurfaceview is the core class in these packages: It serves as a bridge between OpenGL ES and Android's view hierarchy. Makes the open

The implementation of common pro merge le will involve floating point computation and must satisfy the range and accuracy defined in the following "Floating-pointcomputation. The implementation of common pro fi le lite involves fixed-point computing and must meet the range and accuracy defined by "fixed-pointcomputation. However, common pro fi le lite

This problem is not my own encountered is a classmate asked me to install software in linux:/lib/ld-linux.so.2: bad ELF interpreter how to solve, here I have two kinds of analysis, one is commonly used installation because of the number of digits of the system software, for example, 32-bit programs are installed in 64-bit systems, and the other is that the files or directories are not cross-compiled, let's take a look at the solution.

1. Using a buffer object to pass data from multiple vertices to the vertex shader requires the following five steps: 1.1 Create Buffer Object (Gl.createbuffer ()). 1.2 Bind Buffer Object (Gl.bindbuffer ()). 1.3 writes data to the buffer object (Gl.bufferdata ()). 1.4 Assigns the buffer object to a attribute variable (gl.vertexattribpointer ()). 1.5 Turn on the attribute variable (Gl.enablevertexattribarray ()). 2. Create a Buffer object (Gl.createbuffer ()) When using WebGL, you need to call the

judging the inner and outer sides of polygons is explained in detail in the previous article. To deepen the impression, say it again.In WebGL, occlusion culling is not valid by default, and all polygons are drawn regardless of the order in which the vertices are defined. However, when occlusion culling is effective, only polygons that meet certain conditions will be drawn and invisible parts will not be drawn, which will weaken the burden of coordinate calculations. In order to set the occlusio

500px, 300px high. Of course, the size of this canvas can be set according to your needs freely. I set it casually here, nothing special.Next, to get the context of WEBGL, you need to use the GetContext function, the GetContext function is to get the context object from the canvas, the argument is a string, specify the name of the context you want to get.When this article was written (February 2012), the context of WEBGL is not yet available through the official name WebGL, and the context obje

Python is an object-oriented development language, the use of global variables in functions, generally should be described as global variables, only in the function of the described global variables can be used, the following describes the Python global variables related issues. You should try to avoid using Python global variables. Different modules are free to access global variables, which can lead to the unpredictability of global variables. For global variables, if programmer a modifies the

Client-server mode, the command issued by the client does not require an immediate response from the server, if the client and the server in a network, one command will appear inefficient, so the command will be cached in the client and then sent together, so the client needs a mechanism to confirm that the server has completed the execution of the command, Given that OpenGL ES is multithreaded, the execution of thread A is important to synchronize the execution of individual threads, such as th
