Houdini 20.5 Nodes Copernicus nodes

OCIO Transform Copernicus node

Converts color spaces using OCIO transforms.

On this page

Open Color IO allows for standardized transforms between different spaces. This operation provides access to OCIO and will use your current OCIO settings to control the meaning and behaviour.

Parameters

Signature

The layer type that the source accepts.

See Signatures for more information.

Transform Method

OCIO has two main approaches to colour conversion. The first is when moving between two colour spaces - this will handle the remapping fo the different white points and primaries and is invertible. The second is when computing a view transform - this may include tone mapping and is not invertible.

Between Spaces

Transform from one OCIO space to another. The exact meaning of these spaces is depending on your OCIO configuration.

Space to View

Transform from an OCIO space into a view. This requires specifying a view and a display, and will bake the colors into final values that would be used by the hardware.

Original Space

The space the input color is in.

To Space

The desired output color space.

To Display

The desired output display device.

To View

The desired view. This often may include non-linear tone maps.

Note: The choice of view may depend on the current display

Treat RGBA as Premultiplied

Color transforms are defined in RGB, and may be non-linear, so can’t be applied to just the RGB components of a pre-multiplied RGBA layer. This option will first un-premultiply, do the transform, and then premultiply them again. Note this means areas with black alpha will have black output.

Inputs

source

The layer to adjust colors for.

Outputs

transform

The layer with adjusted colors.
