Enabling the
Use Z-Buffer
option uses the focal point set in the render camera of the
3D Blender scene, as shown in following screenshot. Enabling this option disables
Z-Scale.
Z-Scale
Using Z-Scale, focus points can me manually adjusted to the required object in the
image.
The Bilateral Blur node
The Bilateral Blur node implements a high quality adaptive blur on the source foot-
age. This node can be used to soften a grainy ray-traced Ambient Occlusion pass,
smoothing the output from various unbiased renderers. Many heavy performance ef-
fects, such as blurry refractions, reflections, and soft shadows can be attained with
this node. Its components are as follows:
•
Image
: This is the input image that is to be blurred.
•
Determinator
: This is a source that defines the edges/borders for the blur in
the image.
•
Iterations
: This specifies how many times the filter will perform the operation
on the image. This actually defines the radius of the blur.
•
Color Sigma
: This specifies the threshold for which the differences of color
in the image should be considered as edges.
•
Space Sigma
: This is a fine-tuning variable for the blur radius.
