Houdini 21.0 Nodes Copernicus nodes

Pixelate Copernicus node

Increases the size of pixels to pixelate an input layer.

On this page
Since 21.0

This node pixelates an input layer by sampling the layer at a quantized position. The node enhances the size of individual pixels so you can see how many pixel blocks make up the image. The parameters on this node control the amount and size of the pixel blocks. Larger pixel blocks result in blurrier images.

Note

The Blur COP in the Pixelate node’s subnetwork lets you add blurring to the layer before applying the pixelated effect. Turn on and use the Pre-Blur parameters in the Pixelate node to control this blur radius.

Before and after using the Pixelate node.

For example, use this node to create pixel art or mosaic effects.

Parameters

Signature

The layer type that the source accepts.

See Signatures for more information.

Mask

The amount of the new value to mix in with the original value. Higher values mix in more of the new value. Lower values mix in less of the new value.

The default value is 1, which means this node uses only the new value. See Mask for more information.

Mode

The method used to determine the amount of pixel blocks.

Block Size

Set the size of each pixel block to determine how many appear along the X and Y-axes.

Number of Blocks

Set the amount of pixel blocks that can appear along the X and Y-axes.

Units

When Mode is Block Size, this is the unit of measurement used to determine the Block Size.

Image

Sets the block size to use image space units.

Pixels

Sets the block size to use pixels.

Block Size

The size in image coordinates or pixels of the resulting pixel block, which determines how many blocks appear along the X and Y-axes. You can turn on the Per-Component Controls button to adjust this further using the Element Scale parameter.

Element Scale

When the Per-Component Controls button is on, this is the per-axis scaling of the element size for the pixel block.

Number of Blocks

The amount of pixel blocks that can appear along the X and Y-axes across the image space.

Note

The node outputs less blocks than the set amount if the input layer doesn’t expand across the entire image space.

Tile Size

The size (in image space) by which to multiply the input layer’s original pixels before they're pixelated.

Offset

The amount (in image space) to offset the input layer’s pixels before quantizing their position.

Pre-Blur

Pre-Blur

Blurs the input layer’s pixels before they're pixelated.

Units

The unit of measurement that the Blur COP in the node’s subnetwork uses to determine the size of the blur effect’s radius.

Image

Sets the blur radius to use image space units.

Pixels

Sets the blur radius to use pixels.

Size

The size of the blur effect’s radius in image space or pixels, which the Units parameter determines.

Scale Size

The amount to scale the blur effect’s radius.

Inputs

source

The layer to pixelate.

effect

An optional per-pixel scaling amount of the Block Size parameter.

offset

An optional per-pixel addition to the Offset parameter.

mask

An optional per-pixel mask amount that’s scaled by the Mask parameter.

Outputs

pixelate

The pixelated source layer.

blockid

An ID layer that contains a unique ID for each pixel block.
