- Lighting is crucial in 3D data visualization to interpret space as 3D on 2D screens.
- Topographic maps use shadows to transform featureless color blobs into recognizable landscapes.
- Direct light with diffuse shading helps interpret surfaces as 3D, but can hide details.
- Animating light or the model over time can reveal hidden details by changing lighting angles.
- Cinematographers and photographers use fill lights to balance contrast and reveal contours.
- Arranging perfect 3D lighting is complex, involving positioning multiple lights and camera angles.
- Sunset lighting provides balanced direct and indirect light, reducing harsh contrasts.
- HDR environment maps offer natural lighting without micromanaging individual lights.
- The Prague and Hosek atmospheric models generate customizable sky lighting for 3D scenes.
- Real-world location lighting can be simulated using latitude, longitude, and time data.
- Manhattanhenge and Al-Khazneh examples demonstrate precise alignment of lighting with geospatial data.
- Abstract visualizations benefit from atmospheric lighting for soft shadows and highlights.
- The skymodelr package integrates realistic lighting into rayshader for 3D data visualization.
- Night sky modeling is planned for future updates to cover stars, the Moon, and planets.
