Redefine the extraordinary in hand sketching and 2D drawings.
We are providing a sketching approach that preserves many of the advantages of traditional freehand drawings, while simultaneously providing new capabilities that are beneficial for the explorative process.
It utilizes strokes as the main drawing primitive, thereby allowing for fluid interaction. This is in contrast to 3D modeling programs, which struggle with interfaces for specifying 3D geometry and dimensions.
To improves on traditional 2D systems by providing capabilities that are currently thought to be strictly within the domain of 3D modeling. By re-projecting the strokes into new views, we simulate camera motion (panning, tilting, and zooming), thus providing the visual experience of being immersed in the designed space.
At the same time, we provide the capability to draw complex geometric features such as trees, or annotate the drawing with comments and symbols. Such features and annotation are difficult to achieve using 3D geometry and remain a major shortcoming of conventional computer generated scenes.
Our approach also integrates paper sketching and computer drawing in a fashion that permits the selection of the desired mode at any point during the process.
Paper drawings can be superior to ones made with computers because of their fluidity, immediacy, and portability.
On the other hand, the computer facilitates re-projection, editing and refinement. Hence, this dual-mode approach combines the best of both worlds.
A floor plan can be drawn while looking down (a)
After that it will be re-projected into perspective views for vertical line extrusion in (b), (c).
A person starts sketching with the digital notepad (a),
Then imports the drawing into the system (b)
And translates and rotates it to fit the horizon (c).
Precious2D CAD tools are used to align the vanishing points (d).
The sketch can be printed with a different view and new strokes added on paper (e),
Then the import/align procedure is repeated (f).
