Mike,
In the video I just meant to offer a ‘clean’ view. Presumably most render engines offer the option to enable/disable the rendering of curves and points, just like Rhino’s render does.
In the video I use a small red sphere for the target point (to comply to your technique and for the sake of clarity) but I personally mostly use a V-shaped polyline with the pivot at the intersection. Hence there is no need to hide anything before rendering (also the pivot will not be rendered).
A ‘point’ object could also be used, but with the camera visible this can be difficult to track.
