Benefits of technology
Enables seamless integration of paper-based sketches into digital models, reducing the complexity of the design process and maintaining the richness of data, while providing intuitive suggestions for designers, thus improving efficiency and usability.
Problems solved by technology
However, as illustrated below, there are disadvantages in rising such prior art technologies for the purpose of three-dimensional sketching for effective and easy integration into paper / pencil based sketching processes involved in many creative processes.
The user interfaces for these three-dimensional modelers, however, are typically quite complex, relying on the standard WIMP (Windows, Icons, Menus and Pointing devices) interaction metaphor to perform ail tasks, typically using a mouse and keyboard as the primary input devices.
The principal disadvantage in using the current digital three-dimensional modeling software is that the ability of individuals involved in creative processes such as designers (in many different fields of endeavour), artists, and architects (collectively referred to in this disclosure as “designers”) to work in rich physical media is generally not fully leveraged in current WIMP based solutions, as particularized below.
However, there is currently no mechanism for easily integrating the concept sketches into the three-dimensional modeling pipeline and related digital processes.
The disadvantage is that at present, pencil and paper sketches are generally not used for anything more than an external visual reference when designs are created by or for designers using digital creative tools.
This not only represents additional work, but can result in the loss of certain layers of or richness of data.
However, even such interfaces do not adequately leverage the invaluable pencil and paper sketches.
The main disadvantage inherent in the TEDDY and SKETCH systems is that they tend to reproduce the feature curves of the input image on a blank canvas with the designers drawing all parts of the new model.
A further disadvantage of blank canvas and matching algorithm based solutions is that the algorithms in these systems are not robust enough to recognize the hints from human-drawn sketches so as to infer suggestions from the user's hints.
However, the disadvantage of generating too many potential candidates on the scene is that it clutters the scene and presents problems for the average user.
There are also recognition-based systems for handwriting, speech, and text input techniques that also face the problem of resolving ambiguity of among multiple candidates.
Another disadvantage of the prior art inventions is that even if they are able to generate multiple candidate suggestions, the user interface is not conducive to integration of such multiple candidate suggestions into the creative process of designers.
Also, the current digital tools generally require that users learn a new skill set, which constitutes a relatively significant barrier to adoption and use.

Embodiment Construction
[0041]The system of the present invention, in one aspect thereof is best understood as a computer-implemented system for rendering sketches. FIG. 1 illustrates a representative embodiment of the system that includes a computer 10, which computer generally consists of a personal computer including a lap top or table PC, provided that they have a suitable graphics card (not shown) and suitable graphics acceleration to process graphics as described below. The computer is preferably linked to a database 11. The primary input device is a pen 12 on a digitizing tablet 14 such as a WACOM™ tablet. The pen 12 preferably has a barrel button with two click actions—forward, backward, and an active eraser end. Loaded on the computer 10 is the computer application 16 of the present invention, which is the computer program aspect of the present invention. The computer application 16 consists of a special application three-dimensional modeling tool, programmed in a manner that is known, to include ...

A method, computer system and computer program is provided for using a suggestive modeling interface. The method consists of a method of a computer-implemented rendering of sketches, the method comprising the steps of: (1) a user activating a sketching application: (2) in response, the sketching application displaying on a screen a suggestive modeling interface; (3) the sketching application importing a sketch to the suggestive modeling interface; and (4) the sketching application retrieving from a database one or more suggestions based on the sketch. The method is operable to allow a user interactively using the sketching application to create a drawing that is guided by the imported sketch by selectively using one or more image guided drawing tools provided by the sketching application. The present invention is well-suited for three-dimensional modeling applications.
