Navigating a LiveCube
In LumenRT, the mouse is the primary device used to navigate the LiveCube in a manner similar to walking through a 3D video game or orbiting inside a 3D application.
- Walk-Thru
Mode - (The default mode, activated by pressing the F3 key) It is
like a first person video game. The user operates the mouse controls to
"wander" through the model as if he/she was walking through the scene. Pressing
the left mouse button will cause the camera to walk forward. The speed of
walking increases if you keep the mouse button pressed. Simply release mouse
button to reset speed.
The camera is fixed to a height of 1.6 meters above the ground (about the eye level of an average-sized adult). You can move up or down using the Page Up and Page Down keys. The camera will revert to its standard height as soon as you start walking again.
Walk-thru mode is sensitive to obstacles such as walls which will halt movement (and display a halt icon) until the user clicks and releases the mouse to walk through the wall. Features such as stairs will cause the movement to simulate walking up or down the flight of stairs. Users can move up or down to a different floor.
- Fly-thru Mode - (Activated by pressing the F4 key) It is similar to the navigation controls you find in most CAD and CG systems. It allows you to fly around the scene by panning, zooming and rotating the camera.
- Animation Mode - (Activated by pressing the F2 key) It is an optional form of navigation that becomes available if the scene contains an animation path. Animation mode also allows a slide show style of navigation similar to a PowerPoint presentation by moving forward or backward to various scene snapshots using the arrow keys. You can stop animation playback anytime by pressing the left mouse button which will switch to walk-thru mode and start walking from where the camera is (and restore the default height).
First-Person Drive Mode
Included with LumenRT is a python script that enables users to drive through the LumenRT scene using a gaming type driving or racing wheel. The script is also user editable which allows custom driver wheel devices to be interfaced.
To access the Drive Mode script:
- Open the LumenRT Python menu (File)
- Select the menu and run a script
- Navigate to:
C:\Program Files\Bentley\Bentley LumenRT CONNECTtion_UD14\Python\PythonExamples\SDK\DriveMode.py
- The script will then load and run
You can also operate the car mode using the arrow keys.
