• This command shows the effect of placing images on tunnels along the Z-axis and bending them toward a specific point. These images may be placed above, below, to the left or to the right of the Z-axis. An external light source of the specified color and brightness may be shined on the images. The brightness may vary along the z-axis according to the BrightLength value.
• Changing the camera center point, the rotation angle and the viewing screen Z-offset will simulate moving along the axis.
• For an example, see the following figure:
  
  The following figure shows the same image, after the effect has been applied:
  
  To obtain this effect, the following settings were used with the command:
  
  1. CenterPoint = new Point(320, 256)
  2. ZValue = 0
  3. Distance = 200
  4. Radius = 200
  5. Repeat = -1
  6. RotationOffset = 75
  7. Stretch = 25
  8. StartBright = 0
  9. EndBright = 100
  10. BrightLength = 45
  11. BrightColor = FromRgb(255, 255, 255)
  12. FillColor = FromRgb(255, 255, 255)
  13. Flags = TunnelCommandBitmapEffectsFlags.WidthAxis | TunnelCommandBitmapEffectsFlags.Color
• This command does not support signed data images.
