Left-clicking * and dragging will rotate the camera position about the center of the sketch, * right-clicking and dragging will pan the camera position without rotation, * and using the mouse wheel (scrolling) will move the camera closer or further * from the center of the sketch. This function can be called with parameters * dictating sensitivity to mouse movement along the X and Y axes. Calling * this function without parameters is equivalent to calling orbitControl(1,1). * To reverse direction of movement in either axis, enter a negative number * for sensitivity. * @method orbitControl * @for p5 * @param {Number} [sensitivityX] sensitivity to mouse movement along X axis * @param {Number} [sensitivityY] sensitivity to mouse movement along Y axis * @param {Number} [sensitivityZ] sensitivity to scroll movement along Z axis * @chainable * @example *

This function can be called without parameters to create a * default grid and axes icon, or it can be called according to the examples * above to customize the size and position of the grid and/or axes icon. The * grid is drawn using the most recently set stroke color and weight. To * specify these parameters, add a call to stroke() and strokeWeight() * just before the end of the draw() loop. * * By default, the grid will run through the origin (0,0,0) of the sketch * along the XZ plane * and the axes icon will be offset from the origin. Both the grid and axes * icon will be sized according to the current canvas size. Note that because the * grid runs parallel to the default camera view, it is often helpful to use * debugMode along with orbitControl to allow full view of the grid. * @method debugMode * @example *
