The BCC Spiral Blur ﬁlter creates a blur or smear that appears as though
it is spiraling toward the center of the image.
In addition to the ability to adjust the amount of blur, users are able to
fine tune other aspects of the filter:
- The Blur Type menu sets the type of motion blur that is created. The choices are _Blur _or Smear. Smear blurs the pixels in one direction. Blur blurs the pixels symmetrically.
- Center sets the coordinates of the center of the spiral effect. The following example shows a Zoom Amount of 25 applied as a Smear, with no Spin Angle.
- Spin Angle sets the angle of the spiral effect. When Spin Angle is set to 0, no spiral is applied. The following examples show the ﬁrst image above with Spin Angle applied.
The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the ﬁlter should affect.
