Multi-scale Visualization of Molecular Architecture Using Real-Time Ambient Occlusion in Sculptor

Fig 2

Global illumination by ambient light rays (red) emanating from a hemisphere Ω.

The illumination is governed by a weighted sum of unblocked light rays (red) that reach the surface point p, where the weights are given by the cosine of the incident angle relative to the surface normal np. [16, 21, 22].
