LightKit is a system for lighting three-dimensional synthetic scenes. LightKit simpliﬁes the task of producing visually pleasing, easily interpretable images for visualization while making it harder to produce results where the scene illumination distracts from the visualization process. LightKit is based on lighting designs developed by artists and photographers and shown in previous studies to enhance shape perception. A key light provides natural overhead illumination of the scene, augmented by ﬁll, head, and back lights. By default, lights are attached to a normalized, subject-centric, camera-relative coordinate frame to ensure consistent lighting independent of camera location or orientation. This system allows all lights to be positioned by specifying just six parameters. The intensity of each light is speciﬁed as a ratio to the key light intensity, allowing the scene’s brightness to be adjusted using a single parameter. The color of each light is speciﬁed by a single ...
