Data-driven modeling of lighting effects
SynthLight's core competency is its high-quality training datasets built using a physical rendering engine. Using a professional light capture device (LightStage) and a physical rendering pipeline, the tool creates a synthetic face image dataset containing a variety of lighting conditions. This dataset accurately simulates the lighting characteristics of faces under different lighting angles, intensities, and color temperatures, including accurate diffuse, specular, and shadow effects.
- The dataset contains more than 100 base light conditions
- Generate multi-angle face images for each condition
- Accurate labeling of lighting parameters and environment mapping
- Includes multi-ethnic face data from Asia, Europe, Africa, etc.
This training on physically realistic datasets allows SynthLight to generate physically correct lighting effects better than comparable tools that use GAN technology alone, and especially excels when dealing with complex highlight and projection relationships.
