 Modeling by Sketch-Based 3D Parts Composition
|
Jeehyung Lee and Thomas Funkhouser
Two popular approaches in easy 3D modeling methods are sketch
based modeling and modeling by composition of parts from existing
models. While both approaches are easier to use than commercial
modeling systems, sketch based modeling is limited to creating
simple models and modeling by composition requires a lot of user
interventions.
In this project, we introduce a new modeling method
that overcomes these limitations by combining both approaches.
We introduce a modeling system for parts composition with sketching
interface. Our system does not require the user to perform any
complicated geometric operation. The system allows the user to
search a part and composite it to a desired location in the modeling
scene with a single sketch. The main benefit of this approach is that
while it allows to create highly detailed models/scenes - as details
come from parts themselves - the modeling method is still very intuitive
and requires minimal amount of training time.
To enable this
modeling method, we investigate an algorithm for 3D shape search
with 2D sketch as a shape query and an intelligent composition
algorithm which automatically orients/translates/sclaes/attaches a
new part into the modeling scene by taking the user sketch as a hint.
User experiences with our prototype system, SketchParts, show that
even novice users can create interesting and detailed models.
