This page describes the navigation modes of VRweb. You can switch among them by pressing the appropriate button in the toolbar or using the accelerator keys F4 - F8.
Every time you switch the navigation mode you get a short one-line message in the status line describing the functions of the mode. If the line is too long for reading you can scroll it with the middle mouse button.
Note: If your mouse has no 3rd button, the mouse driver of your X-server will emulate the middle one when pressing both mouse buttons simultaneously.
For complementary navigation tools and options see page Navigation Techniques.
Use the flip mode for examination of objects. You manipulate
the object whereas the viewpoint remains stationary.
Tip: To examine details of objects use the fly to tool. After having set a point
of interest, it serves as roation center with control+middle
mouse button in flip mode.
You may also rotate around the center of the selected object
(shift+click) by dragging with shift+middle mouse button in
flip mode.
The walk mode is designed for navigation in scenes. Beginners
may prefer to use the heads up
mode instead. The point where you press the mouse button is marked by
a cross and is used as the origin for speed controls (unless you turn
off the option velocity control).
The fly mode simulates flying through the world with an
aeroplane. The bar on the right side indicates your current flying
speed, the position of the airplane cursor relative to the cross in
the middle indicates your flight direction.
The heads up mode is very simple to use. Icons superimposed on
the scene show you the possible actions. All navigation can be done
using the left mouse button only. Drag the mouse out of an icon and
you perform the appropriate motion.
If you get more experienced (or if you find the icons annoying), the
walk mode offers you the same
possibilities: walking (left), panning (middle), and looking (right).
The fly to mode is an additional tool for examining details in
the scene. A point of interest can be approached rapidly but in a
controlled manner. The target point can also be used as rotation
center for the flip mode.
Tip: scene creators interested in actual 3D coordinates may hold down
the meta (alt) key while setting the point of interest; the
coordinate and normal vector of the hitpoint are written to the
terminal (world coordinate system).
