how to make circular section on a sphere
I want to render a 3D sphere and allow the user to click and drag somewhere. As he drags, render and resize a circular dark section on the sphere starting at the point he originally clicked and ending at the point where the mouse cursor is currently dragging. The circular section needs to be curved with the sphere as when i drag the mouse away from the initial position the circle will grow/expand on the sphere as a coating
