for Rapid Geometric Design

-
This drawing system beautifies your free hand strokes,
and predicts your next drawings.
This applet works only on
Microsoft InternetExplorer 4.0 !!
Detailed manual is here.
How to play
- Drawing lines
- You can draw a free stroke using left button dragging.
- The system beautifies it when you finish drawing.
Red line is the primary candidate, and magenta lines are secondary candidates.
- You can select another candidate by clicking a magenta candidate.
- Primary candidate is settled when you click other area then magenta candidates,
or you draw the next free stroke.
- Predictions
- When you settle the primary, the system predicts the next drawings,
and shows predicted magenata lines.
- If you like a predicted line, click it. The system generates next predictions.
If not, click somewhere else, or draw a free stroke.
- If you click on a black line, the system generates predictions around the line.
- Erasing
- You can erase existing line by drawing scribbling stroke.
Note that what is erased is one closest to the starting point of the scribble.
- You can also erase lines by click-dragging of left botton.
(click-drag is similar to double click, but not to release button after the second button down)
- View Control
- You can scroll screen using right button dragging.
- You can zoom in/out using right button click-dragging.
- Misc
- Save/load is not supported. Please use "Print Screen".
