Agisoft has released De-Lighter, a new free stand-alone tool designed to remove shadows from model textures. This innovative application is designed to eliminate cast shadows and ambient occlusion from 3D models. It empowers users to paint on models, marking approximate areas that are lit or in shadow.
The tool utilizes “rough illumination maps” to classify texture pixels into lit and shadowed groups. The beauty of De-Lighter lies in its user-friendly approach: brush strokes don’t need to be precise, and meticulous painting around boundaries isn’t necessary. According to the documentation, a good markup requires spatially uniform strokes, with one stroke per material to indicate whether it is lit or shadowed.
The de-lighting algorithm is optimized for 8-bit JPEG compressed textures.
