android opengl es 2 0 tutorial

compatibility-developers should consider the device type, Android version and opengles version. Coding convenience-OpenGL es1.0/1.1 API provides a fixed function pipeline and convenient functions, but these functions are not available in es2.0 API. new OpenGL developers may find that writing code with opengles 1.0/1.1 is faster and more convenient.

the gldeletebuffers function to display the delete object handle. glBindBuffer(GL_ARRAY_BUFFER, VBO); In OpenGL, an object is usually bound to a target name. For example, a VBO object is bound to gl_array_buffer (indicating that the buffer is a vertex array, and another common target name is gl_element_array_buffer, index Array), and then execute commands on the target name. These commands will always affect the bound object unless we bind the target

These Android 3D Game Development articles are originally written by Martin, a German, at droidnova.com. lixinso is translated into Chinese. The first part first introduces OpenGL-related terms and guides you to start the first step of 3D development. This series of 3D games is called Vortex. This tutorial focuses on 3D programming. Other things, such as menus an

program handle and the uniform variable name. If the function is successfully called, the index value is returned. If the function fails,-1 is returned. It is also important to check the returned value for errors. This ensures that the shader value is correctly updated. In both cases, the function fails to be called. The first one is the misspelling of the variable name or the optimization operation performed by compiler. In this case, the correct index value cannot be obtained. static float Sc
