GLOBAL ILLUMINATION AND PRINTED LAYER LIGHT TRANSPORT MODELS FOR CUSTOMIZING PHYSICAL PRODUCTS DESIGNED DIGITALLY

A method comprises: generating a user interface; receiving user content to be applied to a surface of a digital product; generating a product description describing the digital product; generating a three-dimensional representation of the digital; generating a texture input-light output map for the digital product; generating calibrated color layers and calibrated luminance layers for the digital product; generating a printed layer light transport model based on the calibrated color layers and the calibrated luminance layers; generating a rendering based on the printed layer light transport model, the calibrated color layers, the calibrated luminance layers, the product description, and the three-dimensional representation of the digital product; transmitting the printed layer light transport model, the calibrated color layers, the calibrated luminance layers, the product description, and the three-dimensional representation of the digital product to a manufacture to cause the manufacturer to manufacture a physical product corresponding to the digital product.
