Circle Splatter node
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The **Circle Splatter** node splats several instances of its input around a circle
|
||||
or a spiral.
|
||||
Overlapping instances are mixed with each other using a *lighten* filter.
|
||||
|
||||
The **Circle Splatter** also has a color version whose input is in RGBA format.

Inputs
|
||||
++++++
|
||||
|
||||
The **Circle Splatter** node accepts two inputs:
|
||||
|
||||
* The *Source* inputs is the image to be splat into the output.
|
||||
|
||||
* The *Mask* input is a greyscale image that is used as a mask and affects each instance's value.

|
||||
|
||||
The **Circle Splatter** node outputs the splat image.
|
||||
|
||||
The greyscale splatter has a secondary output that assigns a random color to each splat instance.
|
||||
|
||||
Parameters
|
||||
++++++++++
|
||||
|
||||
The **Circle Splatter** node accepts the following parameters:
|
||||
|
||||
* *Count*, the number of instances of the source image in the result, including those canceled by the mask.
|
||||
* *Rings*, the number of rings of the circle or spiral pattern.
|
||||
* *Inputs* is the number of alternate shapes in the input (1, 4 or 16). Images containing several
|
||||
shapes can easily be created using the **Tile2x2** node.
|
||||
* *Scale X and Scale Y* are the scale along X and Y axes applied to each instance.
|
||||
* *Radius* is the radius of the outer circle (or distance to center of the outer instance when a spiral is generated)
|
||||
* *Spiral* can be used to select between a circle or a spiral pattern (or anything in between)
|
||||
* *IncRotate* is the rotation increment applied to each instance.
|
||||
* *IncScale* is the scale increment applied to each instance.
|
||||
* *RndRotate* is the maximum angle of the random rotation applied to each instance.
|
||||
* *RndScale* is the amount of random scaling applied to each instance.
|
||||
* *RndValue* is the amount of random value applied to each instance.
