The yellow line shows the spectrum of direct illumination under optimal conditions.
2.
After that, all direct illumination ceases and astronomical darkness sets in.
3.
The other illumination conditions are scaled to show their relation to direct illumination.
4.
Images rendered using global illumination algorithms often appear more photorealistic than those using only direct illumination algorithms.
5.
This fluid may be visible upon direct illumination, but ultrasound may be used to confirm the diagnosis.
6.
The image on the left was rendered with a typical "'direct illumination renderer " '.
7.
For an accurate estimate of direct illumination, a ray is traced from the point of intersection to each light source.
8.
As long as a ray does not intersect another object, the light source is used to calculate the direct illumination.
9.
To facilitate efficiency, the equation is decomposed into four separate factors : direct illumination, specular reflection, caustics, and soft indirect illumination.
10.
The term mass spectroscope continued to be used even though the direct illumination of a phosphor screen was replaced by indirect measurements with an oscilloscope.
