Camera problem

[Montynis]

Hello,

First, thanks for great tutorials.

Now I have got a little problem with a camera class. In third person camera, I call Revolve method when I want to go around the scene:

public void Revolve(Vector3 target, Vector3 axis, float angle)
{
      Rotate(axis, angle);
      axis = Vector3.Transform(axis, Matrix.CreateFromQuaternion(myRotation));
      Quaternion rotate = Quaternion.CreateFromAxisAngle(axis, angle);
      myPosition = Vector3.Transform(target - myPosition, Matrix.CreateFromQuaternion(rotate));

      Update();
}

While rotating it appears to blink and if you let go of the controls at the right moment the objects all dissappear. Why does it happen and how to solve this problem?

Thanks in advance.

Hey Montynis,

sounds like your rotation is performed too fast. I had that Problem when I implemented the Revolve-Function with the textured Quad. Try to decrease the Rotation-
Vaule in your Demoproject when you finally call Revolve.

WotanCameraManager.ActiveCamera.Revolve(Vector3.Zero,
                                                               new Vector3(0, 1, 0),
                                                               mouseDistance.X * 0.003f);

Maybe that helps

Thanks for answer, but this solution doesn't solve the problem. There is another reason which causes the object to appear and dissapear while moving around the scene. I don't have any idea about it
