Channels Visual

Coming up with a visual example of the difference hasn't been easy, but I think I finally got it.

 

-Here is our one channel D-Map. Same thing as Solid Page 3.

 

-Here is our two channel D-Map.

 

So I took a really basic target and it through both D-Maps. I Displaced both of them in a series and animated them. You should be able to see the difference:

For both, I used slightly increased values for Horizontal and Vertical. Started with 3% and went all the way to 15% in increments of 3%. Horizontal and Vertical were the same each time.

In the first one, the Grabitude line is 45° to the lower-right for values above 128 and to the upper-left for values below 128. The brightness value in the D-Map itself determines how far down the line Grabitude grabs from. As you can see, Grabitude, or apparent motion, is limited to those 45° lines.

In the second one, Grabitude is a rectangle. Notice that Grabitude, or apparent motion, is in all sorts of directions.

:whew:

Are you confused?
