A synthetic approach to effectively support 3D computer graphics (3DCG) authoring is proposed. Interactive Evolutionary Computation (IEC) has been applied for the 3D authoring domain and proven to be useful for easily generating aesthetic 3DCG contents even for the novices. The previous systems, however, only focus on a specific subtask out of a whole 3DCG production process. All dominant tasks in the 3DCG production such as geometric modeling, rendering, animation, and 3D data management are covered in our approach. The proposed method reorganizes a monolithic IEC system into a combination of front-end IEC explorer and back-end graphics engines. Because it works on the Internet, some critical applications such as digital prototyping and e-learning come within the range.
