natural sketch into parametric information
the program uses the enactive model of creativity to construct cognitive models of
how humans construct the entire 3D model from sketches at different levels, e.g.,
local, regional, and global. For the system, its local perceptual logic tries to under-
stand the relationship between the geometry, such as the angle between two sketch
lines. Regional perceptual logic attempts to compose nearby sketch lines into coher-
ent part of the model. Global perceptual logic composes those regional perceptual
logic groupings into a meaningful overall model. The second use of the enactive
model is to facilitate the conversation like creation process instead of having users
to execute commands explicitly one by one, such as the traditional CSTs that require
users to execute commands and input complicated equations explicitly. The enac-
tive agent in Solid Sketch sits in the background, perceives the user's actions, inter-
prets his intentions, and leverages its understanding of the user's intention to help
the user achieve their current goal. The fi nal products after interacting with the
system will include not only a 3D model but also a set of parametric rules that
describe how the user created the model (Fig.

Conclusions
Computational creativity has the potential to radically change what it means to
interact with computers. However, in order to reach its full potential, the fi eld needs
a cognitive theory of creativity that accounts for the enactive nature of creativity,
including improvisation, collaboration, and a tight feedback loop with the environ-
ment. In this chapter, we provided a brief summary of the current state of computa-
tional creativity and pointed out the shortcomings of the traditional information
processing view of cognition. We argued that the new cognitive science paradigm of
