OpenGL es Shader language variables and data types (i) (Official document fourth)all variables and functions must be declared before they are used. Variables and function names are identifiers .Without a default type, all variables and function declarations must contain a claim type and an optional modifier. Variables are declared in the first place to indicate the type, followed by a number of variables, separated by commas. In many cases, a variable

What is hybrid? Mixing is to mix the two colors together. Specifically, the original color at a certain pixel location and the color to be painted are mixed together in some way to achieve special effects. Suppose we need to draw a scenario: to look at the green object through the red glass, we can first draw the green object, then draw the red glass. When drawing the red glass, use the "mix" function to mix the red and the original green to get a new color, it looks like the glass is translucen

Author: Rob 'phantom 'Jones Introduction In the previous article OpenGL framebuffer object 101, I introduced some basic FBO applications. The article mainly introduced how to generate a FBO, how to render data to a single texture and apply the texture elsewhere. However, FBO extensions are not the only method to achieve this. In the previous article, we mainly talked about a comprehensive feature of FBO: attachment point ). In this article, we will fu

This article translated from: http://developer.android.com/training/graphics/opengl/shapes.html The first step to create an advanced image is to define the image in the context of the view of OpenGL ES to be drawn. If you do not understand some basic requirements of OpenGL ES to define graphical objects, it is difficult to use

I. Summary By accident, I saw this tutorial on Android Developers and made it step by step. Below is a record. Ii. How to draw OpenGL ES in Android To use OpenGL to draw images in Android applications, we must create a view container. The most direct method is implement.GLSurfaceViewAndGlsurfaceview. Renderer.The former is the container, and the latter controls the rendered content in the view. There are t

Note: The following content is from OpenGL getting started tutorial. Select a part of content for learning ~~~ When we draw a geometric image above, do you think our plot scope is too narrow? Coordinates can only be from-1 to 1, and can only be the right X axis, Y axis up, Z axis vertical screen. These limitations cause a lot of inconvenience to our drawing. We live in a 3D world-if we want to observe an object, we can:1. Observe it from different lo

OpenGL-Non Uniform Rational B-Splines. Toolbox The OpenGL toolbox is collection of routines for the creation, and manipulation of Non-Uniform Rational B-Splines (OpenGL ). have to some extent become the de facto industry standard for representing complex geometric information in CAD, CAE and CAM, and are an integral part of each standard data exchange formats su

Recently, due to interest, I began to learn OpenGL plotting. This article uses "Draw sphere" as a point to summarize what we have learned recently. > OpenGL ES started with OpenGL from Android. As we all know, Android View is thread unsafe, so it is only allowed to operate on the View in the main thread. However, if we need to implement a complex interface, espec

Because of work, I don't have much time to focus on game development. Here we will list some previously collected OpenGL tutorials and share them with friends who like OpenGL and game development. Of course, there are still some good tutorial websites not included in it. You are welcome to add that the title "Top Ten" is completely designed to attract everyone's attention. However, I think for most people,

Original post address: http://ogldev.atspace.co.uk/www/tutorial16/tutorial16.html Texture ing maps an image (or texture) to one or more faces of a 3D model. Textures can be any image, and texture ing can increase the realism of 3D objects. Common textures include bricks, plant leaves, and so on. In comparison, texture ing is used, and texture ing is not used. To use texture ing, we must do the following: Install texture in OpenGL to provide texture c

There are too many good resources and you know too little about them. Now we are starting from scratch !! Fighting ...... Some OpenGL resource links This is a few simple links prepared by myself a few days ago.By the way, some of the tutorials on this http://www.spacesimulator.net website are charged, if you know where you can see the free to inform me, thank you!If you have any questions about how to use OpenGL
