The BCC Directional Blur filter blurs the image by displacing it in one direction. The effect is similar to how a photograph of a speeding object appears if taken with a slower shutter speed.
In addition to advanced controls to fine tune the quality of the blur, the filter allows for detailed control over:
Blur Amount controls the amount of blur applied to the image. Increasing Blur Amount displaces pixels farther in the chosen direction and creates more blur.
Angle sets the direction in which pixels are displaced to create the blur.
- Thin reduces the number of pixels used to compute each point in the blur. Increasing Thin decreases the smoothness of the blur but reduces render time. Higher Thin values produce a “double vision” effect
- Increasing Spread causes each point in the rendered output to be affected more by points farther away from it in the blur, producing a blurred “double vision” effect.
Blur Threshold reduces the amount of color change to each pixel by the threshold amount. Increasing Blur Threshold causes the parts of the image with abrupt changes in color to blur, while areas with subtle details remain unchanged.
The built in PixelChooser, with integrated mocha planar tracking allows for greater control over which areas of the image the ﬁlter should affect.
