FieldVortexRing

The FieldVortexRing node allows you to create vortex ring effects.

Note:  This is a LABS node, indicated in Nuke with the tag:
LABS nodes are experimental and not intended to be used for production.

Snap snap_menu N/A

Set your geometry or pivot location to that of a selection within the scene:

• Geo to selection (position): sets the position of your geometry to the selection within the scene

• Geo to selection (position, orientation): sets the position and orientation of your geometry to the selection within the scene

• Geo to selection (position, orientation, size): sets the position, orientation and size of your geometry to the selection within the scene

• Pivot to selection (position): sets the pivot position to the selection within the scene

• Pivot to selection (orientation): sets the pivot orientation to the selection within the scene

• Pivot to selection (position, orientation): sets the pivot position and orientation to the selection within the scene

Transform Order

xform_order

SRT

Sets the operation order for scale (S), rotation (R), and translation (T). The possible operation combinations are SRT, STR, RST, RTS, TSR, TRS.

Rotation Order

rot_order

ZXY

Sets the order of rotation. The possible axial combinations are ZXY, XYZ, XZY, YXZ, YZX, ZXY, ZYX.

Transform Data

file_menu

N/A

Select to import or export a channel file:

• Import chan file - import a channel file and transform the object according to the transformation data in the channel file. Channel files contain a set of Cartesian coordinates for every frame of animation in a given shot. You can create and export them using Nuke or 3D tracking software, such as 3D-Equalizer, Maya, or Boujou.

• Export chan file - export the translation parameters that you’ve applied to the object as a channel file. This is a useful method of sharing setups between artists.

Translate

translate

0, 0, 0

Lets you translate the object along the x, y, and z axes. You can also adjust translate values by clicking and dragging the object in the 3D Viewer.

Rotate

rotate

0, 0, 0

Lets you rotate the object around the x, y, and z axes. You can adjust rotate values by holding down Ctrl/Cmd and dragging in the 3D Viewer.

Scale

scaling

1, 1, 1

Lets you scale the object on the x, y, and z axes.

Uniform Scale

uniform_scale

1

Lets you scale the object simultaneously on the x, y, and z axes.

Pivot Translate

pivot_translate

0, 0, 0

When you make changes to a 3D object’s position, scaling, skewing, and rotation, these occur from the location of the object’s origin point or pivot. The pivot translate and rotate x, y, and z controls allow you to move and rotate the pivot point as required - you can even move it outside of the object. Subsequent transformations applied then occur relative to the new pivot point location and rotation.

You can hold down Ctrl/Cmd and drag the pivot point to a new location in the 3D Viewer.

Pivot Rotate

pivot_rotate

0, 0, 0

When you make changes to a 3D object’s position, scaling, skewing, and rotation, these occur from the location of the object’s origin point or pivot. The pivot translate and rotate x, y, and z controls allow you to move and rotate the pivot point as required - you can even move it outside of the object. Subsequent transformations applied then occur relative to the new pivot point location and rotation.

You can hold down Ctrl/Cmd and drag the pivot point to a new location in the 3D Viewer.

Local Matrix

Specify Matrix

useMatrix

off

Enable this control to specify matrix values for the object you’re transforming as an alternative to setting transform, scale, skew and pivot values above.

Matrix

matrix

N/A

The matrix displays values from the object’s transform, rotate, scale, skew, and pivot controls.

Check specify matrix and copy or drag-and-drop matrix values from another object to apply those values, for example, if you wanted to align objects in a scene.
Display Tab
Draw Bounding Box preview_bounds off Draw the bounding box of the field if it has one.
Draw Preview (SDF and Density only) preview_on off Draw a rough preview of the field.
Preview Opacity preview_opacity 0.5 The opacity at which to draw the preview.
Scale preview_scale 1 A value by which the field is multiplied before drawing. You may need to increase this to display faint volumes for example.
Offset preview_offset 0 A value added to the field before drawing (after scaling).
Detail preview_detail 1 The detail level at which the preview is drawn. Large values are more accurate but slower to draw.
