Camera Copernicus node

Creates a camera.

On this page	Parameters Transform Pivot Transform Look At View Sampling Metadata Inputs Outputs
Since	22.0

Creates a default perspective camera that’s offset back from the layer’s center based on the Focal Length and Aperture, with an imaging volume that has rays converging on the camera’s Look At Position. This node’s camera settings override the default_camera context option set by the Default Canvas in the COP Network or COP Network SOP.

Wire in a camera_ref input and click Set Parameters from Input to populate the parameters based on the incoming layer’s camera.

See Copernicus cameras for information about how to use this node.

Parameters ¶

Set Parameters from Input

Autofills the camera’s parameters with the settings from the connected camera_ref.

Transform ¶

Transform

Transforms the camera.

Transform Order

The order in which transformations and rotations occur.

Translate

The amount of translation along xyz axes.

Rotate

The amount of rotation about the xyz axes.

Pivot Transform ¶

Pivot Translate

The local pivot space’s translation value for transformations.

Pivot Rotate

The local pivot space’s rotation value for transformations.

Look At ¶

Look At

Sets the look at target.

Look At Position

The target position for the camera to look at.

Up Vector Method

Determines the up vector of the look at.

Y Axis

Use the Y axis as the up vector.

X Axis

Use the X axis as the up vector.

Custom

Set a custom position (Up Vector) to use as the up vector.

Up Vector

A custom position to use as the up vector of the look at.

Twist

Rotates the camera in degrees about the look at axis.

View ¶

View

Sets the view of the camera.

Resolution

Sets the camera resolution in pixels.

Projection

Sets the camera projection type.

Focal Length

Sets the camera’s focal length (zoom) in millimeters.

Aperture

Sets the camera’s horizontal aperture in millimeters, which is the width of the visible field.

The ratio of Focal Length and Aperture determines the offset of the camera. The absolute values are not relevant, so they can be in any unit as long as they're consistent.

Ortho Width

Sets the width of the orthographic view’s volume when the Projection is Orthographic.

Near Clipping

Sets the position of the camera’s near clipping plane.

Far Clipping

Sets the position of the camera’s far clipping plane.

Screen Window X/Y

Defines the center of the window during the rendering process.

Screen Window Size

Expands the cropped area that the Crop parameters specify.

Left Crop

Sets the left cropping margin for the camera’s view area.

Right Crop

Sets the right cropping margin for the camera’s view area.

Bottom Crop

Sets the bottom cropping margin for the camera’s view area.

Top Crop

Sets the top cropping margin for the camera’s view area.

Imaging Distance

Sets how far the layer is (in Houdini units) from the eye of the camera.

Guide Scale

Specifies the scale of the camera that’s displayed when the layer is metadata.

Sampling ¶

Sampling

Sets how the camera samples the layer.

Shutter Open

Sets when the camera starts receiving light (open). This is relative to the frame rate.

Shutter Close

Sets when the camera stops receiving light (closed). This is relative to the frame rate.

Focus Distance

Sets the distance from the camera at which objects are in focus, relative to the layer’s origin.

F-Stop

Sets the camera’s F-stop. Higher values decrease how blurry objects are outside of the Focus Distance.

Metadata ¶

Metadata

Modifies the metadata dictionary.

Entries

Specifies the number of key and value pairs to add or edit in the metadata dictionary. This option can be useful for adding metadata items with simple data types, such as strings or integers.

Key

The string key to insert or modify the value for.

Type

The data type of the dictionary value.

Value

The value to insert into the dictionary for the Key.
