A 3D modeling system for creative design

Abstract

We propose a new approach to easily creating 3 0 geometric models. A technique called interactive evolutionary computation (IEC) is introduced to accelerate user's invention and inspiration of new shapes. The proposed IEC-based design system generates aesthetically pleasing shapes through the simulation of natural evolutionary processes. The user only is required to specrfi hidher subjective preference of each shape generated by the IEC. The system allows even beginners with little knowledge and experiences of the 3 0 modeling to acquire innovative shapes. Because the system is developed based on a 3 0 geometric modeler using implicit surface method, it also provides skilled experts with an advanced modeling interface. The experts can directly modrfi the internal parameters of the 3 0 models to make them more elaborate ones. Some experimental results are presented to show the potential of the proposed modeling method.

Interactive Evolution of Particle Systems for Computer Graphics and Animation

“…for aesthetic appeal). Thus, graphical content generation is a common application of IEC [20], [21], [22], [23], [24], [25].…”

“…IEC applied to art) often vary, including linear or non-linear functions, fractals, and automata. Some notable examples include (1) Mutator [21], a cartoon and facial animation system, (2) SBART (figure 2b) [22], a two-dimensional art exploration tool, (3) a tool that evolves implicit surface models such as fruits and pots (figure 2c) [23], [27], [28], and (4) a system for evolving quadric models used as machine components (figure 2d) [24]. Figure 3 illustrates IEC's content generation capabilities.…”

Compositional pattern producing networks: A novel abstraction of development

“…In general, the encodings used in genetic art systems are not motivated by or based upon natural development. Rather, they are often designed to include intuitive aesthetic features such as shape descriptors [80]. Nevertheless, many such systems do in effect implement what can be described in retrospect as a rough abstraction of development.…”

“…Husbands et al [82] describe a system for interactively evolving three-dimensional shapes that includes both assembling primitives and transform functions such as scaling and twisting that are combined like CPPN function compositions. Nishino et al [80] introduces a similar system that combines deformable three-dimensional primitives, which effectively encodes visual artifacts.…”

Interactively evolving harmonies through functional scaffolding

“…IEC can encompass a variety of digital media [15,22], including images [11,26,6], movies [25], three dimensional models [14], and music [9,13,3,4,8,24]. GenJam is an example IEC application in which users help to build improvisational accompaniments or soloists by rating the measures and phrases as either good or bad [3].…”
