HUD Controls
The HUD contains the same controls as the Inspector, with the exception of the Mix
control.
Ring Lens
This filter creates a ring of distortion over the image. The result can be a donut-like
bulge in the image. This filter causes rasterization in 3D groups.
Parameters in the Inspector
Center: Sets the position of the center of the lens.
Radius: Sets the radius of the ring. Values range from 0 to 1000.
Thickness: Sets the thickness of the ring as a percentage of the radius. Values range
from 0 (no thickness) to 1.00 (no hole in the center of the ring lens).
Refraction: Sets the amount of refraction of the lens. Values range from –5 to 5.
HUD Controls
The HUD contains the Radius, Thickness, and Refraction controls.
Ring Warp
Similar to the Ring Lens, but the image is distorted with multiple concentric rings. The
number of rings can be increased or decreased using the Radius and Refraction
parameters.
