opengl functions tutorial

tutorial code, we wrapped these common functions and created the technique class, its Inheritance class will focus mainly on shader special effects. Each technique must first call the init function for instantiation. The derived class of techniqu must first call the init function of the base class (this function creates an OpenGL program object ), you can also a

(openggl.gl_quads) This cube is the uint type, which is 7, Front OpenGL many open and close functions are also a UINT type) Gl.normal is the normal direction of the specified face, the orientation of the specified face can make the lighting effect more realistic, especially when importing large 3D objects, in fact, the complex 3D object is also composed of multiple triangular patches (TRIANGLE), if you do

Glsudo CP GL opengl.sh/bin/You can then use the command GL Test.cpp to create the OpenGL code template, and if you want to modify it, just modify the opengl.sh, do not need to recompile CPP--------------------------------------------------------------------------------------------------------------- --------Find yourself more and more like the Linux programming environment, the command line is really super awesome! I'm not used to writing code with V

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 and program lifecycles, are part of the code bu

at the same time. Now, click "Build and Go" to see what you get:Welcome to you, 3d objects. How does one map the texture?I think what we need now is not just a solid color object. Let's use the texture in the previous tutorial to map six faces to make the cube more exciting. Okay, let's keep the texture Loading Function in our project. We only need to modify our drawView function. Now, I will show you how to perform one-time rapid texture ing. First,

making objects move according to a preset program, such as a rotating triangle, can draw attention. But what if you want users to interact with your OpenGL ES graphics? The key to making your OpenGL ES app Touch Interactive is to extend the Glsurfaceview, Ontouchevent () method to listen for touch events. This tutorial shows how to listen for a revealing event an

This lesson will teach you how to use three different texture filtering methods. It also teaches you how to use a keyboard to move objects in a scenario and how to use simple light in an OpenGL scenario. This course contains a lot of content. If you have any questions about the previous course, first review it. Before entering the code below, it is very important to have a good understanding of the basic knowledge.We still modify the code in Lesson 1.

each frame. GLUT does not repeatedly call our rendering functions. Rendering operations are performed only when special events occur, such as window maximization and minimization, and the current window is blocked by other windows, if we do not make any changes after the program is executed, the rendering function will only execute once. We can add a print function to the rendering function to verify the function. When the window is maximized and min

GLUT Tutorial MouseIn the previous sections, we saw how to use the keyboard function of GLUT to increase the interaction of an OpenGL program. Now it's time to study the mouse. The glut mouse interface provides some column options to increase the interaction of the mouse. That is, to detect mouse clicks and move the mouse. Detect mouse ClicksLike keyboard processing, Glut provides a method for registering
