The UnderWorld CheatSheet page.

The aim of this page is to serve as a CheatSheet for UnderWorld users to either bookmark in their browser or print out and stick on the wall.

If you have good tips or tricks, commonly used commands or pieces of advice and you think it would be good to broadcast these to the UnderWorld community please add it to this page.

Some more ideas ...

• options that make the code run fast
• more handy aliases
• command line commands
• parallel debugging on valgrind
• useful svn commands, including svn update -r "{" 2007-05-18 "}"

Interactive Visualisation Controls

Note: an image and all those after it will be saved according to the camera view set when you close the interactive window. To avoid this, when you have finished trying out the controls, point to a viewport with your mouse and press the "r" key on your keyboard to reset the camera for the viewport - repeat for each viewport before closing the window or advancing to the next timestep.

The following controls are listed in the terminal window each time an image is displayed on the screen:

Mouse Interaction:

• Left Button: Rotate camera around model.
• Middle Button: Zoom camera in or out of the model.
• Right Button: Move camera's focal point (currently unavailable).

Keyboard Interaction:

• escape: Exit out of program.
• q, space: Close window and continue running program.
• h: Print this help message.
• i: Toggle Window Interactivity.
• r: Reset camera for viewport under cursor.
• s: Output information for camera associated with viewport under cursor.
• [: Zoom out with camera associated with viewport under cursor.
• ]: Zoom in with camera associated with viewport under cursor.
