Geometry
Kaleidoscope
A kaleidoscope with N sectors mirrored around the centre.
Controls
- sectors
- How many wedges the circle is cut into. Six is the toy tube, twenty-four is a snowflake
- angle
- Turns the finished pattern rigidly, the way a hand turns the tube — it does not pick a different piece of the photo
- mirror
- Mirrored wedges meet without a seam; plain rotated copies break at every border, which is the harder, more graphic look
- zoom
- How close the picture is sampled around the centre. A ratio, so two means twice as large at any output size
- center x
- A number from 0 to 1, 0.5 by default.
- center y
- A number from 0 to 1, 0.5 by default.
