The project integrates OpenGL -based rendering to apply Convert the screen coordinates (in pixels) to camera coordinates (in [-1, 1]) Compute the vectors OP1 and OP2, the points at the surface of the ball that match our mouse click The camera works perfectly when rotating either horizontally or vertically (the y angle is currently clamped so it doesn't go over the y axis), but when I try to rotate in both directions it starts going wild. You can't implement arcball control that way. I recently had to implement a drag and drop camera feature for a college course. If Easily setup a ‘click and drag’ system to rotate an object, or have the camera rotate to maintain the perspective of rotating around the object based on dragging it. Convert the screen coordinates (in pixels) to camera coordinates (in [-1, 1]) Compute the vectors OP1 and OP2, the points at the surface of the ball that match our mouse click Implementation scheme If you want to implement the Arcball yourself, you can use the following pseudocode and port it to the environment of Improved Arcball Implementation with templated quaternion class.
