has its strengths and weaknesses (see table 1 ). This document does not describe any of the four methods. There are only two ways to transplant OpenGL code from other platforms: the SDK package class for OpenGL ES and the NDK that can be used to develop OpenGL ES in C/C ++. For the other two methods, the SDK Canvas ap

What is 1,opengl? OpenGL (Full-write open graphics Library) is a professional graphics program interface that defines a cross-programming language, cross-platform programming interface specification. It is used for three-dimensional image (two-dimensional also), is a powerful, easy to call the bottom-level graphics library.What 2,
OpenGL rendering Pipeline
OpenGL first receives the user-provided geometry data (vertices and geometry) and enters it into a series of shader stages for processing, including vertex coloring, subdivision coloring (which itself contains two shaders), and the final geometry coloring, which is then fed into the rasterization unit (rasterizer). The Rasterization unit is responsible for Tu Yuanshong the metadat

The general process has been explained in the first two chapters. When designing an Http server, I designed a four-layer structure. The bottom layer is the network transmission layer, that is, socket programming. The next layer is the Request and Response layer, called Request and Response. The

vertices of the triangle, it is time to start setting up the Vao. First, we should enable the vert variable in the shader program. These variables can be turned on or off, which is off by default, so we need to turn it on. The vert variable is a "property variable (attribute variable)", which is why there is a "Attrib" in the OpenGL function name. We can see more types in the subsequent articles.

After creating a model in 3dmax, save the model as an ASE file (ASCII file) in a triangular mesh mode. in the program, we need to create a corresponding model data structure. This article uses the C language data structure as an example.
The example ASE file contains a simple pyramid and sphere. The specific content is as follows (the header is omitted ):

Using OpenGL ES 2.0 to draw a graph may require more code than you think, because the API provides a large number of graphic rendering pipeline control interfaces.This chapter describ
