Sun/Moon Size

The size of the sun or moon can affect the overall mood of your scene, especially when simulating a sunset's horizon illusion. The Disk Size can be used alone to modify the size of the sun and moon but the Horizon Illusion is dependent on the Disk Size.

If you've ever watched a sunset, you probably noticed that the sun appeared to get larger as it approached the horizon. The same is true for the moon. At certain times of the month it appears huge. This illusion can be simulated using Sun/Moon size. When the illusion is active, the sun or moon will appear to grow larger as it approaches the horizon.

To change the size of the Sun or Moon as it approaches the horizon:

1. Display the Sky & Fog palette by clicking the Sky & Fog button at the top of the Bryce window.
   
   
2. Click the Sky Lab button. The Sky Lab appears.
   
   
3. Click the Sun & Moon tab.
   
   
4. Enable the Sun/Moon Visible option.
   
   
5. Enable the Sun/Moon Size option.
   
   
6. In the Sun/Moon Size area, enter a value in the Disk Size field or drag the slider to set the overall size of the sun/moon anywhere in the sky.
   
   
7. Enter a value in the Horizon Illusion field or drag the slider to set multiplier used to determine how much larger the sun or moon gets as it approaches the horizon.
   
   
8. Click the OK icon to exit the dialog.

Examples:

• Disk Size = 25; Horizon Illusion = 5
  
  
• Disk Size = 25; Horizon Illusion = 25
  
  
• Disk Size = 10; Horizon Illusion = 25
  
  
• Disk Size = 35; Horizon Illusion = 25
