Bilateral Blur Node¶
The Bilateral Blur node performs a high-quality adaptive blur, blurring the image while retaining sharp edges.
It can be used for various purposes like: smoothing noisy render passes to avoid longer computation times in example ray-traced ambient occlusion, blurry refractions/reflections, soft shadows, or to make non-photorealistic compositing effects.
Inputs¶
- Image
Standard color input. If only the image input is connected, the node blurs the image depending on the edges present in the source image.
- Determinator
If connected, it serves as the source for defining edges/borders for the blur in the image. This has great advantage in case the source image is too noisy, but normals in combination with Z-buffer can still define exact borders/edges of objects.
- Size
The size of the blur in pixels.
- Threshold
Pixels are considered in the blur area if the average difference between their determinator and the determinator of the center pixel is less than this threshold.
Outputs¶
- Image
Standard color output.
