ねえ、私はopenglで三角形を描こうとしています. 私はそれを行うためにチュートリアルに従っただけです。すべてがうまくいっているように見えても、うまくいきません。コードを実行するたびに、メイン メニューに戻ります。
デバッグ後、アプリケーションがその行で停止していることに気付きました
gl.glDrawElements(GL10.GL_TRIANGLES, pIndex.length, GL10.GL_UNSIGNED_SHORT, pBuff);
これは私の GLExample.java クラスです
public class GLExample extends Activity {
GLSurfaceView ourSurface;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ourSurface = new GLSurfaceView(this);
ourSurface.setRenderer(new GLRendererEx());
setContentView(ourSurface);
}
@Override
protected void onPause() {
super.onPause();
ourSurface.onPause();
}
@Override
protected void onResume() {
super.onResume();
ourSurface.onResume();
}
}
これは私の GLTriangleEX クラスです
public class GLTriangleEx {
private float vertices[] = {
0f, 1f, // p0
1f, -1f, // p1
-1f, -1f // p2
};
private FloatBuffer vertBuff;
private short[] pIndex = { 0, 1, 2 };
private ShortBuffer pBuff;
public GLTriangleEx() {
// her bir float için 4 byte gerektiğinden length * 4 oldu
ByteBuffer bBuff = ByteBuffer.allocateDirect(vertices.length * 4);
bBuff.order(ByteOrder.nativeOrder());
vertBuff = bBuff.asFloatBuffer();
vertBuff.put(vertices);
vertBuff.position(0);
ByteBuffer pbBuff = ByteBuffer.allocate(pIndex.length * 2);
pbBuff.order(ByteOrder.nativeOrder());
pBuff = pbBuff.asShortBuffer();
pBuff.put(pIndex);
pBuff.position(0);
}
public void Draw(GL10 gl) {
gl.glFrontFace(GL10.GL_CW);
gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
gl.glVertexPointer(2, GL10.GL_FLOAT, 0, vertBuff);
gl.glDrawElements(GL10.GL_TRIANGLES, pIndex.length,
GL10.GL_UNSIGNED_SHORT, pBuff);
gl.glDisableClientState(GL10.GL_VERTEX_ARRAY);
}
}
これは私の GLRendererEx.java クラスです
public class GLRendererEx implements Renderer {
private GLTriangleEx tri;
public GLRendererEx() {
tri = new GLTriangleEx();
}
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig eglConfig) {
gl.glDisable(GL10.GL_DITHER);
gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_FASTEST);
gl.glClearColor(.1f, 0f, .9f, 1f);// set background color
gl.glClearDepthf(1f);
}
@Override
public void onDrawFrame(GL10 gl) {
gl.glDisable(GL10.GL_DITHER);
gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
gl.glMatrixMode(GL10.GL_MODELVIEW);
gl.glLoadIdentity();
GLU.gluLookAt(gl, 0, 0, -5, 0, 0, 0, 0, 2, 0);
tri.Draw(gl);
}
@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
gl.glViewport(0, 0, width, height);
float ratio = (float) width / height;
gl.glMatrixMode(GL10.GL_PROJECTION);
gl.glLoadIdentity();
gl.glFrustumf(-ratio, ratio, -1, 1, 1, 25);
}
}
