Kaleidoscopes Unveiled

From Filter Forge Wiki

Jump to: navigation, search

Kaleidoscopes can add many a nice detail to your filter, and they have a nice help page, but what that help page is missing is an exact description of what each Kaleidoscope mode is and does. This makes it hard to find the mode you want, and where the offsets must be to achieve the effect wanted.

So, to remedy this shortcoming, lets go through the Kaleidoscope modes. In the following, the source image shows you where the Kaleidoscope will get the part of the picture it uses, and which parts it doesn't (the last in black). Three colored blobs were added to make it easier to spot which orientation the sub image is used in. These are for the default Shape Size of 50.

Shape Size

Secondly, how does the Shape Size affect where the image comes from ? Well, here is how Shape Size affects the original area:

Image:ShpSz25.jpg Image:Kal_Tr1.jpg
Shape Size 25 Shape Size 50
Image:ShpSz75.jpg Image:ShpSz100.jpg
Shape Size 75 Shape Size 100
Image:Res_Tr1.jpg
Result (same for all above)

As you can see, Shape Size increases the selected aea as it increaes, with the top left corner staying fixed where it is.


Offsets H & V

Offset H and V just offset the area selected, as you can see here:

Image:Kal_Rm1.jpg Image:Kal_Offs33x00.jpg
Offset H 0,00 V 0,00 Offset H 33,33 V 0,00
Image:Kal_Offs66x00.jpg Image:Kal_Offs33x40.jpg
Offset H 66,67 V 0,00 Offset H 33,33 V 40,00


Repeat H & V

Repeat H and V just give you a free repeat of the result image in a rectangular tiling:

Image:Res_Rm2.jpg Image:ResDbl.jpg
Repeat H 1 V 1 Repeat H 2 V 2
Image:ResTri.jpg Image:ResTriOne.jpg
Repeat H 3 V 3 Repeat H 3 V 1
