java opengl tutorial

It is very simple to construct an OpenGL view on the andorid platform. There are two main tasks: Glsurfaceview The OpenGL es api provided by the Android platform is mainly defined in the package android. openGL, javax. microedition. khronos. EGL, javax. microedition. khronos. opengles, Java. among several packages such

Simon iPhone-OpenGL ES tutorial-04 OpenGL ES 04-color and texture As my last tutorial said, I'm tired of drawing white objects on the screen, so that we can add some colors, just like the project automatically generated by the apple module. Next I will introduce you to pay attention to these concepts, because these co

Android OpenGL ES plotting tutorial 3: Drawing GraphicsAfter defining the shapes to be drawn by OpenGL, you certainly want to draw them. 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

OpenGL ES Tutorial for Android-Part III-Transformations January 1st, 2010 by Per-Erik Bergman-Android,Embedded Last tutorial was about building your polygons. this tutorial is all about transformations, how to move the polygons around. I will continue this tutorial from wher

final Texture unit color based on the texture coordinates, and combine these colors with the color of the dot element or the color calculated based on the illumination to output the final color of the pixel. In the following tutorial, we will see that the Texture unit can contain different data and implement many special effects. OpenGL supports 1d, 2d, 3D, cube, and many other textures, which are used in

understand, now just need to know that this function can showwindow, and wait for the window to close before returning, which is enough. ）In the Glutdisplayfunc function, we set the "Call Mydisplay function when drawing is required." So the Mydisplay function isUsed for drawing. Observe the three function calls in Mydisplay and find that they all start with GL. This function, starting with GL, is OpenGL.Standard functions, the functions used are described below.1, Glclear, clear. Gl_color_buffe

Guidance: Modern OpenGL Tutorial 01--Getting Started GuideIn this article, we'll add a map to the triangle, which involves adding some new variables to the vertex and fragment shader, creating and using the mapped object, and learning a bit about the mapping unit and mapping coordinates.This article uses two new classes into the Tdogl namespace: Tdogl:bitmap and Tdogl:texture. These classes allow us to uplo

Lesson 1Image Font: In this lesson, we will create some fonts Based on 2D images that can be scaled but cannot be rotated and always oriented to the front, but as a basic display, I think it is enough.Welcome to another tutorial. This time I will teach you how to use bitmap fonts. Maybe you will say to yourself, "What is the difficulty of displaying text on the screen ?". But once you try it, you will know that it is really not that easy. Of course, y
