Walk Thru

Walk Thru animation tool.

The tool allows you to navigate in a scene. The navigation can be recorded and used in the following ways:

The tool uses the mouse and keyboard input to control the orientation of the camera similar to many games: moving the mouse controls the direction and the four keys a, w, d and s allow you to move forward, bacward and sideways. Collision detection system is used for automatic floor and wall detection.

To use the tool, press down the mouse in a view window. This will activate the navigation for the window and you can then control the orientation of the camera by moving the mouse.

The keys 'w', 'a', 'd' and 's' can be used for walking forward, left, right and backwards. The mouse wheel controls the focal lenght (zoom) of the camera.

The tool supports large number of options, well known from real world cameras.

Options

Action

Controls whether the tool creates an animated camera or animates the selected objects.

Walk

Set the maximum walking speed (m/s). The Shift key can be used for slowing the velocity down. The actual speed can also be slower when approaching walls: the tool automatically slows the user down near walls to give the user more time to react.

Turn

Controls the rotation speed.

Height

The height of the Observer (altitude). The camera will be elevated this much above the ground.

Threshold

Controls the key generation in motion recording. This value is relative to the defined turning and walking speed. The value of 0 means the motion is always recorded, no matter how much the camera moves or turns. This will result lots of key frames. The value of 1.0 means the motion is practically recorded only when the camera rotates full 360 degrees, or moves more than the given walking speed.

Gravity

Gravity on/off. If gravity is off, the user will be able to climb on the walls and fly.

Collision

Enable or disable Collision Detection. If the option is set, then the tool will detect floor and walls and it is not possible to pass through any surfaces.

Stabilizer

Image stabilizer. Smooths out shaking and sudden jumps.

Auto Focus

Auto Focus. Sets focusing distance automatically by detecting the distance to the nearest surface in front. When enabled, the tool renders a focusing frame representing the users dimensions on the scene. Autofocus option is useful when rendering animations with Dept-of-Field effect.

Input Plane

Manage Input Plane orientation. The orientation for the input plane is determined automatically from the surface in front of the camera. If the Input Grid is not shown, then the tool renders a small rectangle to visualize the input plane. This option is useful when modeling new objects to the scene: just walk thru the scene and create objects while you go.

Record

Enable camera motion recording. When set all navigation actions are recorded.
