opengl とコマンド gl.glroate を使用してオブジェクトを回転させようとしていますが、何も起こっていないようです。どこが間違っているのか教えてもらえますか? 以下はコードです
import javax.media.opengl.*;
import javax.media.opengl.glu.GLU;
import javax.swing.JFrame;
import com.sun.opengl.util.Animator;
import com.sun.opengl.util.FPSAnimator;
public class Cube2 implements GLEventListener {
private float Rotate = 0.0f;
private static final GLU glu = new GLU ();
/**
* @param args
*/
public static void main(String[] args){
JFrame frame = new JFrame("A simple JOGL demo");
GLCanvas canvas = new GLCanvas ();
canvas.addGLEventListener(new Cube2());
frame.add(canvas);
frame.setSize(640, 480);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
Animator animator = new FPSAnimator(canvas, 60);
animator.add(canvas);
}
@Override
public void display (GLAutoDrawable glDrawable){
final GL gl = glDrawable.getGL();
//gl.glClear(GL.GL_COLOR_BUFFER_BIT);
gl.glClear(GL.GL_DEPTH_BUFFER_BIT);
gl.glLoadIdentity();
gl.glTranslatef(0.0f, 0.0f, -7.0f);
gl.glRotatef(Rotate++, 1.0f, 0.0f, 0.0f);
gl.glRotatef(Rotate++, 0.0f, 1.0f, 0.0f);
gl.glRotatef(Rotate++, 0.0f, 0.0f, 1.0f);
gl.glBegin(GL.GL_TRIANGLES);
//Counter Clockwise Front Face 1
gl.glColor3f(0.0f, 1.0f, 0.0f); //Green
gl.glVertex3f (1.0f, 1.0f, 0.0f); //Top
gl.glVertex3f(-1.0f, 1.0f, 0.0f); // left to right
gl.glVertex3f (-1.0f, -1.0f, 0.0f); //left
gl.glVertex3f (-1.0f, -1.0f, -0.0f); //left
gl.glVertex3f(1.0f, -1.0f, -0.0f); //left to right
gl.glVertex3f (1.0f, 1.0f, -0.0f); //left
// Right Face 2
gl.glColor3f(1.0f, 0.0f, 1.0f); //Pink
gl.glVertex3f (1.0f, 1.0f, 0.0f);
gl.glVertex3f(1.0f, -1.0f, -0.0f);
gl.glVertex3f (1.0f, 1.0f, 1.0f);
gl.glVertex3f (-1.0f, -1.0f, -0.0f);
gl.glVertex3f(-1.0f, 1.0f, 0.0f);
gl.glVertex3f (-1.0f, -1.0f, -1.0f);
gl.glEnd();
}
@Override
public void displayChanged (GLAutoDrawable arg0, boolean arg1, boolean arg2)
{
//TODO Auto-generated method stub
}
@Override
public void init(GLAutoDrawable glDrawable)
{
final GL gl = glDrawable.getGL();
int width = 640;
int height = 480;
//Set the state of out new OpenGL context
gl.glViewport(0, 0, width, height);
gl.glMatrixMode(GL.GL_PROJECTION);
gl.glLoadIdentity();
glu.gluPerspective(45.0f,(float)(width)/(float)(height),1.0f,100.0f);
gl.glMatrixMode(GL.GL_MODELVIEW);
gl.glLoadIdentity();
gl.glShadeModel(GL.GL_SMOOTH); //Enable Smooth Shading
gl.glClearColor(0.0f, 0.0f, 0.0f, 0.5f); //Black Background
gl.glClearDepth(1.0f); //Depth Buffer Setup
gl.glEnable(GL.GL_DEPTH_TEST); //Enables Depth Testing
gl.glDepthFunc(GL.GL_LEQUAL); //The Type of Depth Testing To Do
gl.glEnable(GL.GL_CULL_FACE); //Start culling back faces
gl.glHint(GL.GL_PERSPECTIVE_CORRECTION_HINT, GL.GL_NICEST); //Really Nice Perspective Calculations
}
@Override
public void reshape (GLAutoDrawable arg0, int arg1, int arg2, int arg3, int arg4){
//TODO Auto-generated method stub
}
}
よろしくお願いします。
