Geometry-Aware Texture Generation for 3D Head Modeling with Artist-driven Control
This addresses the problem of streamlining artistic workflows in virtual character creation, offering incremental improvements in control and efficiency.
The paper tackles the labor-intensive process of creating realistic 3D head assets for virtual characters by introducing a framework that provides artists with intuitive control over geometry and texture generation, resulting in diverse outputs with clean geometries.
Creating realistic 3D head assets for virtual characters that match a precise artistic vision remains labor-intensive. We present a novel framework that streamlines this process by providing artists with intuitive control over generated 3D heads. Our approach uses a geometry-aware texture synthesis pipeline that learns correlations between head geometry and skin texture maps across different demographics. The framework offers three levels of artistic control: manipulation of overall head geometry, adjustment of skin tone while preserving facial characteristics, and fine-grained editing of details such as wrinkles or facial hair. Our pipeline allows artists to make edits to a single texture map using familiar tools, with our system automatically propagating these changes coherently across the remaining texture maps needed for realistic rendering. Experiments demonstrate that our method produces diverse results with clean geometries. We showcase practical applications focusing on intuitive control for artists, including skin tone adjustments and simplified editing workflows for adding age-related details or removing unwanted features from scanned models. This integrated approach aims to streamline the artistic workflow in virtual character creation.
