A Reproducible AI-Assisted Workflow for Concept Development in Stage Art Design and Lighting Optimization through the GSAD Framework

Artificial intelligence (AI) is fundamentally reshaping creative design processes by enabling rapid ideation and consistent visualization, particularly within stage art and scenography. However, existing workflows remain heavily dependent on manual sketching and subjective interpretation, limiting scalability and reducing reproducibility across design teams. This gap underscores the need for a structured, AI-assisted generative stage art design (GSAD) framework that integrates deep learning, generative modeling, and optimization techniques to support systematic and repeatable concept development. The core objective of the GSAD framework is to combine diffusion models for initial concept generation, generative adversarial networks (GANs) for texture and lighting refinement, and intelligent elephant clan optimization (IECO) for optimizing stage layout and lighting placement. The Stage Art Design Dataset, comprising 2,500 high-resolution images, includes annotated theater scripts, lighting diagrams, and 3D layouts to facilitate multimodal learning. Experimental evaluation demonstrates substantial improvements in qualitative metrics, including improved semantic alignment between script content and generated visuals, and greater layout optimization efficiency achieved through IECO-driven spatial analysis. Implementing the framework in a Python-based environment resulted in 98.88% predictive accuracy, 26.58 mega floating-point operations per second (MFPOs), and a parameter quantity of 1.08 M. The GSAD framework presents a scalable, reproducible, and technically robust AI-assisted workflow that enhances creative output, ensures visual consistency, and supports efficient concept development in modern stage art design.
