Map Channel: Sets the channel used to calculate the height vertices. If a height map is

from the source object. Values can be selected from the following: Luminance (default),
Red, Green, Blue, or Alpha.
Mix: Sets the amount of the filtered frame to be mixed with the original source frame.
Values range from 0 to 100%.
HUD Controls
The HUD contains the Front Size, Back Size, Fuzziness, Height Map, and Map Channel
controls.
Slit Scan
Create an animated fly-through effect by simulating the slit scan process used to create
“stargate” images in science fiction films.
This filter causes rasterization in 3D groups.
Parameters in the Inspector

Rotation: Sets the angle of rotation of the slit.
Speed: Sets the speed of the simulation. Values range from 0 to 400.
Perspective: Sets the angle of perspective on the object. Values range from 0 to 1.
Glow: Sets the amount of the glow on the slit. Values range from 0 to 1.
