In: 3D View/HDRI Tools
Physical Sun and Sky implementation based on Hosek-Wikie skylight model. Provides an excellent base for an artifical HDRI.
- Sun Position:
range = [0,1]x[0,1] (longitude-latitude angles)
- Turbidity: 1.0 - 10.0
Turbidity ranges from 1 to 10
- Albedo: 0.0 - 1.0
Albedo ranges from 0 to 1.
- Ground Color: (Color value)
Color of the ground plane.
- Exposure (EV): -1.0 - 4.0
Exposure value of resulting output.
- Sun Size: 0.0 - 4.0
Scale of the Sun, any value different than 1 is non physically correct. Value has subtle effects!
- Sun Intensity: 0.0 - 1.0
Intensity of sun disc. Sun disc is fairly small so effect is not immediately visible.
- Sky Intensity: 0.0 - 1.0
Intensity of the sky. Also affects flaring of sun in the sky, not the disc itself.
