OpenGL learning diary-2015.3.13 -- Multi-instance rendering, opengl-2015.3.13Instancing or instancd rendering is a method for continuously executing multiple identical rendering commands. The rendering results produced by each command are slightly different. It is a very effective method that uses a small number of api calls to render a large number of ry. OpenGL

Today's implementation is to draw a rectangle on the Window object, and you can customize the coordinates of the rectangle, the length width, the color of the border's size, whether it fills, and the color when it fills.The main idea is to draw a border with a line, then draw a rectangle inside, and then choose the transparency of the rectangle according to the pattern of whether it is filled or not, and if it shows, the opacity is 1, and the opacity is 0.The following is the code for the rectan

1.2 OpenGLArchitecture OpenGL supports multiple platforms, including Windows , liunx , and MACOs and UNIX . If the application Program does not use a large number of OS-related calls, therefore, porting the OpenGL program between different platforms is quite simple. Windows has an absolute advantage in the desktop operating system. therefore, the winodows application that develops

Http://developer.3dlabs.com/downloads/shadergen/ 3dlabs 'shadergen is a tool that automatically generates OpenGL shading language shaders that duplicate fixed function OpenGL behavior. the new V3.0 generates thousands of additional shaders with support for separate specular lighting, multiple texture objects, multiple texture coordinate sets and the texture combine environment mode. the purpose of shader

OpenGL is an open system independent of any window system or operating system. Although it contains many graphical functions, it does not have window functions or functions that read events from the keyboard or mouse. Therefore, it is quite difficult for beginners to write a complete graphic program. In addition, OpenGL graphic functions only provide the basic ry: points, lines, and polygon. Therefore, it i

It is a modeling language rather than a programming language. Compared with many programming languages, its biggest feature is parallelism. That is, in fact, it not only describes serial operations, but also describes parallel operations. If you understand the parallel design principles of the OpenGL, the designed system is not only well-defined, but also easy to understand and maintain. For example, for the streaming lamp of programming entry, assumi

This article is the second part of the two sections, discussing the obstacles to porting OpenGL games to Google Android. Before you start a game implant project (including differences in OpenGL extensions, floating point support, texture compression formats, and the GLU Library), you should recognize these obstacles. It also describes how to use OpenGL ES to set

OpenGL is a graphics library based on customer/server and pipeline. That is, an applicationProgram(Customer) writes various commands and data to the pipeline. This command and data will be temporarily saved, and the graphics library (server) will not start to process them until it receives a special command, and send the processing result to the user through a pipeline.Therefore, the basic structure of the OpenGL
