Hi All,
This is the implementation of my SurfaceView Class
@Override
public void surfaceCreated(SurfaceHolder holder)
{
Log.v("My3DClass", "surfaceCreated");
egl = (EGL10)EGLContext.getEGL();
if(egl == null)
Log.v("Error","unable to load EGL");
EGLDisplay dpy = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
if(dpy == null)
Log.v("Error","unable to load Display");
int[] version = new int[2];
egl.eglInitialize(dpy, version);
if(version[0]<1)
Log.v("Error"," unable to initilize version ");
int[] configSpec = {
EGL10.EGL_RED_SIZE, 5,
EGL10.EGL_GREEN_SIZE, 6,
EGL10.EGL_BLUE_SIZE, 5,
//EGL10.EGL_ALPHA_SIZE, 0,
EGL10.EGL_DEPTH_SIZE, 16,
// EGL11.EGL_STENCIL_SIZE, EGL11.EGL_DONT_CARE, //
don't care about stencils
EGL10.EGL_SURFACE_TYPE, EGL10.EGL_WINDOW_BIT,
EGL10.EGL_NONE
};
EGLConfig[] configs = new EGLConfig[1];
int[] num_config = new int[1];
if(!egl.eglChooseConfig(dpy, configSpec, configs, 1,
num_config))
Log.v("Error","unable to choose Config ");
EGLConfig config = configs[0];
EGLContext ctx = egl.eglCreateContext(dpy, config,
EGL10.EGL_NO_CONTEXT, null);
if(ctx == null)
Log.v("Error","unable to create context");
EGLSurface surface = egl.eglCreateWindowSurface(dpy, config,
this, null);
if(surface == null)
Log.v("Error","unable to create surface");
if(!egl.eglMakeCurrent(dpy, surface, surface, ctx))
Log.v("Error","unable to make surface current");
mEglContext = ctx;
mEglDisplay = dpy;
mEglSurface = surface;
}
@Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2,
int arg3)
{
gl = (GL10)mEglContext.getGL();
if(gl == null)
Log.v("Error","unable to load G L");
gl.glViewport(0, 0, getWidth(),getHeight());
gl.glDisable(GL10.GL_DITHER);
gl.glClearColor(0,1,1,0);
gl.glEnable(GL10.GL_SCISSOR_TEST);
gl.glScissor(0, 0, arg2, arg3);
gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
egl.eglWaitNative(EGL10.EGL_NATIVE_RENDERABLE, null);
gl.glMatrixMode(GL10.GL_PROJECTION);
gl.glLoadIdentity();
GLU.gluPerspective(gl, 45f, getWidth()/getHeight(), 0.1f,
100);
gl.glMatrixMode(GL10.GL_MODELVIEW);
mAnimate = true;
Draw3D();
}
public void Draw3D()
{
egl.eglWaitNative(EGL10.EGL_NATIVE_RENDERABLE, null);
gl.glClear(GL10.GL_COLOR_BUFFER_BIT |
GL10.GL_DEPTH_BUFFER_BIT);
gl.glLoadIdentity();
GLU.gluLookAt(gl, 0, 0, -20, 0, 0, 0, 0, 1, 0);
gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
gl.glFrontFace(GL10.GL_CCW);
gl.glVertexPointer(3, GL10.GL_FLOAT, 0, mVertexBuffer);
gl.glDrawElements(GL10.GL_TRIANGLE_STRIP, 3,
GL10.GL_UNSIGNED_SHORT, mIndexBuffer);
egl.eglWaitGL();
egl.eglSwapBuffers(mEglDisplay, mEglSurface);
}
@Override
public void run()
{
while(true)
{
Draw3D();
}
i don't find my screen rendering... is there any problem in my code...
Please suggest...
thanks & regards,
K.Prabhakar
