Hello,
I can't understand why the Y rotation stays to 0 in the following example.
I use the device as a camera. I trace in the Label the 3 values I get from
rotation.
X and Z work fine, Y is 0.
If anybody have an idea of my mistake...
Thank you in advance
Denys
Initialisation
...
//View
matWorld = Matrix4.Identity; // permet d'initialiser la matrice avec une
valeur connue
aspectRatio = (float)(Size.Width) / (float)(Size.Height);
matProjection = Matrix4.CreatePerspectiveFieldOfView (((float)(Math.PI) /
180.0f) * 45.0f,
aspectRatio, 1.0f,
20.0f);
matView = Matrix4.CreateTranslation (0f, 0f, 8f);
matWorldViewProjection = matWorld * matView * matProjection;

GyroData_Received);

gyroRotX = -(float)currentDeviceMotion.Attitude.Pitch;
gyroRotY = -(float)currentDeviceMotion.Attitude.Yaw;
gyroRotZ = -(float)currentDeviceMotion.Attitude.Roll;
la_debug.Text = string.Format
("gyro X: {0:00000} \nY: {1:00000} \nZ:
{2:00000}",
gyroRotX, gyroRotY, gyroRotZ);
}
}
