35.4.3 Ride and Fly

Walk and fly are two other methods of navigation through interrelated 3D models that precisely simulate the visualization of a three-dimensional object as if we were walking towards it, in the first case, or as if we were flying over it. In other words, with “Walk”, we view a model from the XY plane, while with “Fly” the XY plane constraint is overcome by moving the crosshair along the Z axis as well.
As you will recall, we could access the Ride and Fly options from the context menu of the Orbit command, although in fact they are in the section Animations of the Render tab, since its use is associated to the navigation of the models at the time we record Videos of said navigation.
When we activate the Ride mode, a window called Position Locator appears, which shows, from an aerial view, both our position with respect to the model and the position of our sights. In this window we can make the adjustment of both parameters and some others. Then we can use the cursor arrows or keys W, A, S and D to take steps towards our model. The movement of the mouse changes the focus, which is equivalent to turning in any direction.

In this navigation mode, Walk, our position with respect to the Z axis, ie the height of the crosshair, remains constant. Instead, in Flight mode, advancing with the keys also modifies the height of our position, just as if we were flying over our model. The use of the mouse remains the same: move the crosshair.

Finally, we have a dialog box where we can change the distance with which each step is progressed, ie with each keystroke, as well as the number of steps per second if it is kept pressed.
