A Tool for Adaptive Lighting Design

This research introduces an adaptive lighting design tool for 3D interactive environments, designed to solve the challenge of maintaining aesthetic lighting quality despite unpredictable user interaction.

• The proposed adaptive lighting tool utilizes a design-by-example approach, allowing artists to define target aesthetics by providing a reference image from which the system extracts lighting direction and intensity contrast metrics.
• To maintain real-time performance, the system pre-calculates a five-dimensional response surface that maps camera direction, key light direction, and fill intensity to specific shading outcomes.
• The engine employs stochastic gradient descent at runtime to dynamically adjust lighting parameters, balancing natural scene illumination with the artist's predefined aesthetic goals.
