 The Blend Function provides a way of completely changing
the look of a component by re-mapping the transition blend between the two primary colors (or percent or bump). This is done by linking the Blend Function to a Generator component.
Figure F1shows several examples of Blobs Blend Function linked to different generators. In the first example, the Blend
Function is linked to a linear function. This results in no change in the texture since the linear function maps the gradient to an identical gradient. The second example uses
an inverted linear gradient which inverts Blobs color gradient which in turn inverts the Blobs.
The third example shows Blobs linked to the Bell generator. As you can see, this results in rings instead of the blob
shape. To understand this better, look at Figure F2. To see how an original color is mapped to a new color, follow a specific shade of color from the Input Blend Axis up to
the curve and then left to the color on the Output Blend Axis. The input shade is re-mapped to the output shade. In Figure F2, you can see that the darkest and lightest shades of the original gradient (input) are both
mapped to the darkest shade of purple. The middle shade of purple is mapped to the lightest shade of purple.
The right side of Figure F2 shows what the original gradient looked like and what it will become after the Blend Function is linked to a Bell generator. |
