Its slower than mixare

[GoogleCodeExporter]

Its based on mixare but objects on camera screen are moving way more slowly 
than mixare's. Can it be fixed?

It seems much faster at rendering on my phone. I am doing some additional 
filtering to smooth the compass data, you can turn that off and see if it helps.

In the class LowPassFilter there is an ALPHA variable. If you make that value 
closer to 1 it should do less smoothing.

You could also trying not using the smoothing at all, in class SensorsActivity:
Change:
        if (evt.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
            smooth = LowPassFilter.filter(evt.values, grav);
            grav[0] = smooth[0];
            grav[1] = smooth[1];
            grav[2] = smooth[2];
        } else if (evt.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD) {
            smooth = LowPassFilter.filter(evt.values, mag);
            mag[0] = smooth[0];
            mag[1] = smooth[1];
            mag[2] = smooth[2];
        }
To:
        if (evt.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
            //smooth = LowPassFilter.filter(evt.values, grav);
            grav[0] = evt[0];
            grav[1] = evt[1];
            grav[2] = evt[2];
        } else if (evt.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD) {
            //smooth = LowPassFilter.filter(evt.values, mag);
            mag[0] = evt[0];
            mag[1] = evt[1];
            mag[2] = evt[2];
        }

You can also try disabling collision detection:

In class AugmentedReality, set the variable useCollisionDetection to false.

They didn't work quite but changing this line

sensorMgr.registerListener(this, sensorGrav, SensorManager.SENSOR_DELAY_NORMAL);
sensorMgr.registerListener(this, sensorMag, SensorManager.SENSOR_DELAY_NORMAL);

to

sensorMgr.registerListener(this, sensorGrav, SensorManager.SENSOR_DELAY_UI);
sensorMgr.registerListener(this, sensorMag, SensorManager.SENSOR_DELAY_UI);

worked. 
Thanks for this project by the way, its really cool.

Yea, That's another good option to speed things up. I am guessing I don't see 
the same problems because my processor is a bit quicker.
