Hello everyone.
I'm currently working on some kind of strategy game. My idea was to have a camera that moves along a dome. The camera position is defined by two angles and the distance from the center of the world, because the camera always looks at (0;0;0). This might change later. I now have to restrict the camera not to move up to (0;distance;0) because that is where it flips over and I also need to have a limit, so that it cannot look at the world from below.
My first approach was mostly vector-algebra based and didn't seem to work at all. I then thought about using lookAt, but the camera acts kinda strange.
Here is the code (the constraints are still missing):
// Position on the sphere
Vector3f pos = new Vector3f((float)(distance * Math.sin(angleX) * Math.cos(angleY)),
(float)(distance * Math.sin(angleX) * Math.sin(angleY)),
(float)(distance * Math.cos(angleX)));
// Update the camera
cam.setLocation(pos);
cam.lookAt(new Vector3f(), new Vector3f(0.0f, 1.0f, 0.0f));
cam.update();
Is there maybe another camera class, that could deal with this problems easier?
thank you.
