  1. OpenGL Texture help in JOGL

    @Thorim a 32~*32 colours is 1024 int and 4096 bytes using arga. So I don't know what you are thinling but thanks for trying. @Glass_Knife thank you for pointing out my stupidity. I'm such a fool!
  2. I am having problems with textures. Please tell me where I'm going wrong. Here is all the code I used. I'm trying to add a texture to the square. This will eventually be part of an object making program. package ObjectMaker; import com.sun.opengl.util.Animator; import java.awt.Frame; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import java.nio.IntBuffer; import java.util.Random; import javax.media.opengl.GL; import javax.media.opengl.GLAutoDrawable; import javax.media.opengl.GLCanvas; import javax.media.opengl.GLEventListener; import javax.media.opengl.glu.GLU; /** * ObjectMaker.java <BR> * author: Brian Paul (converted to Java by Ron Cemer and Sven Goethel) <P> * * This version is equal to Brian Paul's version 1.2 1999/10/21 */ public class ObjectMaker implements GLEventListener { public static final Random rnd = new _Random( System.currentTimeMillis() ); public static final ObjectMaker objectmaker = new ObjectMaker(); private int[] textures, image; int width, height; private IntBuffer ib; private GLU glu; public ObjectMaker(){ width = 32; height = 32; image = new int[ width * height ]; for( int o = 0; o < image.length; o++ ){ int x = o % width, y = o / width; image[ o ] = (int)Math.floor( Math.sqrt(x * rnd.nextFloat() + y * rnd.nextFloat() )); } ib = IntBuffer.wrap( image ); glu = new GLU(); } public static void main(String[] args) { Frame frame = new Frame("Simple JOGL Application"); GLCanvas canvas = new GLCanvas(); canvas.addGLEventListener( objectmaker ); frame.add(canvas); frame.setSize(640, 480); final Animator animator = new Animator(canvas); frame.addWindowListener(new WindowAdapter() { @Override public void windowClosing(WindowEvent e) { // Run this on another thread than the AWT event queue to // make sure the call to Animator.stop() completes before // exiting new Thread(new Runnable() { public void run() { animator.stop(); System.exit(0); } }).start(); } }); // Center frame frame.setLocationRelativeTo(null); frame.setVisible(true); animator.start(); } public void init(GLAutoDrawable drawable) { // Use debug pipeline // drawable.setGL(new DebugGL(drawable.getGL())); GL gl = drawable.getGL(); System.err.println("INIT GL IS: " + gl.getClass().getName()); // Enable VSync gl.setSwapInterval(1); // Setup the drawing area and shading mode gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); gl.glShadeModel(GL.GL_SMOOTH); // try setting this to GL_FLAT and see what happens. textures = new int[ ]{ 0 }; buildTestTexture(gl); } public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) { GL gl = drawable.getGL(); GLU glu = new GLU(); if (height <= 0) { // avoid a divide by zero error!

  3. I have a big problen with Netbeans 7.1.2

    I just realized that i did not do something very elementary. I should have used new MemoryImageSource! Unlike c++ you new new to create a class in Java!!
  4. I have a big problen with Netbeans 7.1.2

    I did not define a classpath but the path for my library project is OK and is not where MemoryImageSource should be anyway and thus irrelevant.
  5. I have a big problen with Netbeans 7.1.2

    Now it finds the package but not the class!! I've copied and pasted to no effect. Thanks for the help LJ_1102
  6. I have a big problen with Netbeans 7.1.2

    NetBeans puts a red wiggly line under it and says it can't find it. In other words it is not defined anywhere. I found it by looking in a zip file and found that out by looking for Image. Here are the imports: import java.awt.Image.*; import java.awt.Image.MemoryImageSource;   MemoryImageSource package and class do not exist according to NetBeans but it does! I downloaded NetBeans 7.3 and get the same problem but also can't find it manually. I'm creating a library so breakpoints are worthless. It is simple symbol not found issue.
  7. I'm in the process of writing an alternative to hardware acceleration without using raycasting. Its based on taking the screen as a sheet and moving that as a whole. While i have much done the thing that is a current problem is getting it on the screen. The problem is how. In c/c++ i could use createbitmapindirect, slow but possible and there might be a faster way but i want to do it in Java. The problem is how? In the manual it saysuse MemoryImageSource. Tried and failed. Why? Netbeans can't find it! I searched and found it easily and can't see why Netbeans can't. Its been imported correctly, even copied and paste. Does anyone have a clue what to next?
