Abstract:
This thesis investigates the geometric representation of ideas during the early stages of design. When a designer’s ideas are still in gestation, the exploration of form is more important than its precise specification. Digital modelers facilitate such exploration, but only for forms built with discrete collections of high-level geometric primitives; we introduce techniques that operate on designers’ medium of choice, 2-D sketches. Designers’ explorations also shift between 2-D and 3-D, yet 3-D form must also be specified with these high-level primitives, requiring an entirely different mindset from 2-D sketching. We introduce a new approach to transform existing 2-D sketches directly into a new kind of sketch-like 3-D model. Finally, we present a novel sketching technique that removes the distinction between 2-D and 3-D altogether.
This thesis makes five contributions: point-dragging and curve-drawing techniques
for editing sketches; two techniques to help designers bring 2-D sketches to 3-D; and a
sketching interface that dissolves the boundaries between 2-D and 3-D representation.
The first two contributions of this thesis introduce smooth exploration techniques
that work on sketched form composed of strokes, in 2-D or 3-D. First, we present a
technique, inspired by classical painting practices, whereby the designer can explore
a range of curves with a single stroke. As the user draws near an existing curve, our
technique automatically and interactively replaces sections of the old curve with the
new one. Second, we present a method to enable smooth exploration of sketched form
by point-dragging. The user constructs a high-level “proxy” description that can be
used, somewhat like a skeleton, to deform a sketch independent of the internal stroke
description.
Next, we leverage the proxy deformation capability to help the designer move
directly from existing 2-D sketches to 3-D models. Our reconstruction techniques
generate a novel kind of 3-D model which maintains the appearance and stroke structure
of the original 2-D sketch. One technique transforms a single sketch with help
from annotations by the designer; the other combines two sketches. Since these interfaces are user-guided, they can operate on ambiguous sketches, relying on the designer to choose an interpretation.
Finally, we present an interface to build an even sparser, more suggestive, type of
3-D model, either from existing sketches or from scratch. “Camera planes” provide
a complex 3-D scaffolding on which to hang sketches, which can still be drawn as
rapidly and freely as before. A sparse set of 2-D sketches placed on planes provides
a novel visualization of 3-D form, with enough information present to suggest 3-D
shape, but enough missing that the designer can ‘read into’ the form, seeing multiple
possibilities. This unspecified information - this empty space - can spur the designer
on to new ideas.
