Using 3D Mapping
It is possible to add more than one transformation to the same fractal layer, so let’s do just that.
The idea of the 3D Mapping transformation is to map the fractal layer onto a three-dimensional surface. Let’s first use the default, Plane shape. |

As you can see, our kaleidoscopic flower shape has been mapped onto the lower half of the fractal and the top half of the image is now black. This gives the effect of a floor extending toward the horizon. We can make this mapping shift to the top half of the image, to become more of a sky-effect, by changing one of the transformation parameters. It is not immediately clear which of the parameters effects this change, so now is a good time to learn another way to get Help. | ||||
The tool window will display a help text for the parameter currently under the mouse cursor. In this case, a little investigation tells us that the parameter we need to change in order to make our fractal appear in the “sky” is the Y Translation parameter. It is currently set to -0.5.

Now… what is this big black area doing in our image? Some transformations, like Lake and Kaleidoscope warp the fractal but still fill the entire image. |

Others, like the 3D Mapping transform, map the fractal onto an object or create a mask that does not fill the entire image. The leftover area that is not fractal is filled with a solid color, which is designated on the Mapping tab.
To change the solid color from the default Black to another color, adjust the sliders. You will see the changes immediately on your image. But what we really want to do in this image is to make the black area transparent.
Now we can see both the Lake effect from the bottom layer and the Kaleidoscopic flower in the sky plane of our top layer.
