Here is a Screenshot that maybe makes clear what my problem ist. http://img69.imageshack.us/img69/1030/screenshotedges.png I'm only drawing 2D circles with OpenGL. I allready read the following: - http://stackoverflow.com/questions/3512456/how-to-draw-smooth-line-with-antialias - http://gamedev.stackexchange.com/questions/47584/how-to-draw-a-smooth-circle-in-android-using-opengl?answertab=votes#tab-top - http://stackoverflow.com/questions/4934367/how-to-get-rid-of-jagged-edges-in-android-opengl-es and added the Blender Funktion. But nothing worked or even made a diffrence. This is my Renderer: public class GLRendererTamago implements Renderer{ private GLTamago tama; public GLRendererTamago(){ tama = new GLTamago(); } @Override public void onSurfaceCreated(GL10 gl, EGLConfig config) { gl.glDisable(GL10.GL_DITHER); gl.glDisable(GL10.GL_DEPTH_TEST); gl.glEnable(GL10.GL_BLEND); gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_FASTEST); gl.glClearColor(.8f, 0f, .2f, 1f); gl.glClearDepthf(1f); } @Override public void onDrawFrame(GL10 gl) { gl.glDisable(GL10.GL_DITHER); gl.glDisable(GL10.GL_DEPTH_TEST); gl.glMatrixMode(GL10.GL_MODELVIEW); gl.glLoadIdentity(); GLU.gluLookAt(gl, 0, 0, -5, 0, 0, 0, 0, 2, 0); tama.draw(gl); } @Override public void onSurfaceChanged(GL10 gl, int width, int height) { // TODO Automatisch generierter Methodenstub 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, 20); } and this my object: public class GLTamago{ private int points = 1000; private float vertices[]={0.0f,0.0f,0.0f}; private FloatBuffer vertBuff; public GLTamago(){ vertices = new float[points * 2]; for(int i=0; i< points; i+=3) { double rad = 2*(Math.PI *i) / points; vertices[i]=(float)Math.cos(rad); vertices[i+1]=(float)Math.sin(rad); vertices[i+2]=0; } ByteBuffer bBuff=ByteBuffer.allocateDirect(vertices.length*4); bBuff.order(ByteOrder.nativeOrder()); vertBuff=bBuff.asFloatBuffer(); vertBuff.put(vertices); vertBuff.position(0); } public void draw(GL10 gl){ body(gl); lefteye(gl); righteye(gl); mouth(gl); } private void body (GL10 gl){ gl.glPushMatrix(); gl.glTranslatef(0, 0, 0); gl.glScalef(2.0f, 3.0f, 1.0f); //Skalierung einstellen gl.glColor4f(1.0f,1.0f,1.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); } private void lefteye (GL10 gl){ gl.glPushMatrix(); gl.glTranslatef(1, 1, 0); gl.glScalef(0.5f, 0.5f, 1.0f); //Skalierung einstellen gl.glColor4f(0.0f,0.0f,0.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); gl.glPushMatrix(); gl.glTranslatef(1, 1, 0); gl.glScalef(0.1f, 0.1f, 1.0f); //Skalierung einstellen gl.glColor4f(1.0f,1.0f,1.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); } private void righteye (GL10 gl){ gl.glPushMatrix(); gl.glTranslatef(-1, 1, 0); gl.glScalef(0.5f, 0.5f, 1.0f); //Skalierung einstellen gl.glColor4f(0.0f,0.0f,0.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); gl.glPushMatrix(); gl.glTranslatef(-1, 1, 0); gl.glScalef(0.1f, 0.1f, 1.0f); //Skalierung einstellen gl.glColor4f(1.0f,1.0f,1.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); } private void mouth (GL10 gl){ gl.glPushMatrix(); gl.glTranslatef(0.0f, -1.0f, 0.0f); gl.glScalef(1.8f, 0.5f, 1.0f); //Skalierung einstellen gl.glColor4f(0.0f,0.0f,0.0f, 1.0f); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertBuff); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points/2); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glPopMatrix(); } } At the edges you can see pixels... and i have no idea how i can fix this. Can someone pls help me? thx I often heard to try anti-aliasing and/or shaders... but i don't have any idear how that works etc. [1]: https://i.sstatic.net/N1rEB.png
