3d Modeling of Trees from Freehand Sketch
نویسنده
چکیده
We present an interface for quickly and easily modeling 3D trees from freehand sketch. The system generates a 3D geometry from 2D sketch on the basis of our observation that trees spread their branches uniformly. Our system also supports several interfaces for editing the 3D tree by drawing additional strokes. These editing operations include adding a branch, cutting a branch and erasing a branch. Besides these interfaces, we propose a method for modeling a 3D tree by selecting branches predicted and displayed. Our system predicts and displays branches that will grow on the existent 3D tree model produced from freehand sketch and gestures. And then a user can continue to model the 3D tree by selecting the predicted branches with gestures. This interface makes it possible to model more complex and natural-looking trees.

Interactive Geometric Modeling Using Freehand Sketches
CAD software and similar modeling systems can show 3D object models created by designers, but these advanced 3D systems demand precise data about the 3D object, especially in the steps of inputting data and making freeform surfaces. Although it has become common to use CAD/CAM systems to increase the efficiency of the industrial design process, traditional sketching is often more efficient in t...
متن کاملSketch-based modeling: A survey
User interfaces in modeling have traditionally followed the WIMP (Window, Icon, Menu, Pointer) paradigm. Though functional and very powerful, they can also be cumbersome and daunting to a novice user, and creating a complex model requires considerable expertise and effort. A recent trend is toward more accessible and natural interfaces, which has lead to sketch-based interfaces for modeling (SB...
متن کاملWhat You Sketch Is What You Get: 3D Sketching using Multi-View Deep Volumetric Prediction
Sketch-based modeling strives to bring the ease and immediacy of drawing to the 3D world. However, while drawings are easy for humans to create, they are very challenging for computers to interpret due to their sparsity and ambiguity. We propose a data-driven approach that tackles this challenge by learning to reconstruct 3D shapes from one or more drawings. At the core of our approach is a dee...
متن کاملOngoing Research on Adaptive Layered Manufacturing from Overtraced Freehand Sketch
Freehand sketch on a paper is commonly seen being used as it is an effective convenient way to express rough ideas. The sketch is typically transformed to be a 3D CAD model by a designer for subsequent operations such as rapid prototyping process where a physical prototype is fabricated from a 3D CAD model. To speed up the realization of an idea, a research called adaptive layered manufacturing...
متن کاملSMARTPAPER: An Interactive and User Friendly Sketching System
This paper describes an interactive sketching system for 3D design/modeling that diverts from the conventional menu and button interfaces of CAD tools. The system, dubbed SMARTPAPER, offers a unified sketching environment that supports direct sketching as well as gestured sketching with more emphasis on the former to encourage natural sketching styles. SMARTPAPER also provides a unified 2D and ...
