Technical Slop

Circle Grads Continued

No more mucking about with just horizontal or vertical Displacement. Time to step it up.

This is our new target graphic. Pretty much the same. Only minor changes. I'll be discussing the extra white dots, but not in this discussion. For now, just note that they are pulled to the center.

Still basic.

Once again, our old friend. We have a good working relationship, so we'll stick with it. Same as before: White in the center and Grey on the outside.

Still basic, too.

Let's Displace with two *gasp* two positive values. We'll stick with 39% all around.

Horizontal: 39%
Vertical: 39%

Tada! That's what happens.

Horizontal grabbed from the right and vertical grabbed from below. They did it at the same time, which resulted in diagonal grabbitude.

Horizontal: -39%
Vertical: -39%

Here we have it with two negative values. It did the exact opposite of two positives. Grabbed from the left and above.

Does this sound familiar?

Horizontal: 39%
Vertical: - 39%

From the right and above.

Getting the hang of this?

Horizontal: -39%
Vertical: 39%

From the left and below.

And now we have this again.

What happens is that the above becomes "upside down" so to speak.

With positive values, Black grabs from the left and from above.

Horizontal: 39%
Vertical: 39%

See? The exact opposite all over again.

Are you starting to get the hang of this? I hope so. What I really hope is that you play with some of this stuff on your own and accurately predict the results. That would be too cool

That was all well and fun, but it was only a taste of gradients. Some basic warping. Let's take a closer look at gradients with Gradients.
