ImageToPoints

Converts an image into a points primitive, with a point for each pixel in the image. Point positions may be defined either by the original pixel coordinates or an image layer providing position data. Arbitrary image channels may be converted to additional primitive variables on the points, and transparent pixels may be omitted from the conversion.

Note

Only pixels within the display window are converted. To include overscan pixels, use a Crop node to extend the display window.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The output scene.

enabled

The on/off state of the node. When it is off, the node outputs an empty scene.

name

The name of the object in the output scene.

sets

A list of sets to include the object in. The names should be separated by spaces.

transform

The transform applied to the object.

image

The image to be converted into a points primitive.

view

The view within the image to be converted.

position

The image channels used to provide 3d positions for the points. If None, the pixel’s 2d position within the image is used instead.

primitiveVariables

The image channels to be converted to primitive variables on the points primitive. The chosen channels are converted using the following rules :

• The main RGB channels are converted to a colour primitive variable called Cs.

• <layerName>.RGB channels are converted to a colour primitive variable called <layerName>.

• Other channels are converted to individual float primitive variables.

width

The width of the points. If widthChannel is used as well, then this acts as a multiplier on the channel values.

widthChannel

The channel used to provide per-point width values for the points primitive.

ignoreTransparent

Omits pixels from the points primitive if their alpha value is less than or equal to alphaThreshold.

alphaThreshold

Threshold used to exclude pixels from the points primitive when ignoreTransparent is on.
