android - How to use sensors rotation matrix in min3d to rotate parsed object -


i want rotate objects parsed .obj file in min3d. need use rotation matrix got sensors. know how in pure opengl can't figure out use (min3d.core.renderer probably?) , how in min3d.
min3d , parses .obj files nicely don't want abandon , use pure opengl. know can use rotate() method uses eulers angles , need use rotation matrix. here's code:

public class hurleyloading extends rendereractivity implements sensoreventlistener{  private object3dcontainer hurleymodel; private sensormanager sensormanager; private sensor sensoracc; private sensor sensormagnetic;   private float[] acceldata = new float[3];  private float[] magnetdata = new float[3];  private final float[] rotationmatrix = new float[16]; float[] orientation = new float[3];  @override public void oncreate(bundle b){     super.oncreate(b);     setrequestedorientation(activityinfo.screen_orientation_portrait);     sensormanager = (sensormanager)getsystemservice(sensor_service);     sensoracc = sensormanager.getdefaultsensor(sensor.type_accelerometer);     sensormagnetic =  sensormanager.getdefaultsensor(sensor.type_magnetic_field);  } public void onresume() {     super.onresume();     sensormanager.registerlistener(this, sensoracc, sensormanager.sensor_delay_game);     sensormanager.registerlistener(this, sensormagnetic, sensormanager.sensor_delay_game); } public void onstart() {     super.onstart();     sensormanager.registerlistener(this, sensoracc, sensormanager.sensor_delay_game);     sensormanager.registerlistener(this, sensormagnetic, sensormanager.sensor_delay_game);     //this.onresume(); } public void onpause() {     super.onpause();     sensormanager.unregisterlistener(this); }  @override public void initscene() {      scene.lights().add(new light());     scene.lights().add(new light());     scene.lights().add(new light());     scene.lights().add(new light());     scene.lights().add(new light());     scene.lights().add(new light());     scene.lights().add(new light());      iparser parser = parser.createparser(parser.type.obj,             getresources(), "ie.tyndall.hurleyopengl:raw/hurley_obj", true);     parser.parse();      hurleymodel = parser.getparsedobject();     hurleymodel.scale().x = hurleymodel.scale().y =  hurleymodel.scale().z = 1.4f;     hurleymodel.position().y = -1.8f;     hurleymodel.position().x = .4f;      scene.addchild(hurleymodel);         } @override public void updatescene() {     /**some rotation code can go here rotation() method has use       * eulers angles (x/y/z euler rotation of object, using euler angles.       * units should in degrees, match opengl usage)which no use me      * need use rotation matrix      **/         }  //@override public void onaccuracychanged(sensor arg0, int arg1) {     // todo auto-generated method stub       } @override public void onsensorchanged(sensorevent event) {       loadsensordata(event);       sensormanager.getrotationmatrix(rotationmatrix, null, acceldata,                  magnetdata); } private void loadsensordata(sensorevent event) {       final int type = event.sensor.gettype();       if (type == sensor.type_accelerometer) {        acceldata = event.values.clone();       }       if (type == sensor.type_magnetic_field) {        magnetdata = event.values.clone();       } } }

i think have calculate angle rotation matrix , set in updatescene() this: obj.rotation().x = ? obj.rotation().y = ? obj.rotation().z = ?

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
