FieldTrilinearWarp

The FieldTrilinearWarp node generates a field which represents a trilinear warp. Each corner of a bounding box can be moved and then each point in the box maps to the appropriate point in the new box.

The field can be fed into FieldWarp or GeoFieldWarp to warp other fields or geometry.

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

Reset Shape To Input

reset_shape

N/A

Cancels your changes and resets the input to its original shape.

Copy

 copy_shape

N/A

Copies the current positions of the bounding box corners (p0-p7) into a temporary buffer.

Paste

 paste_shape

N/A

Pastes previously copied positions of the bounding box corners (p0-p7).

Set Key

 set_key_shape

N/A

Sets keys for the positions of all the bounding box corners (p0-p7) on the current frame. This is the same as selecting Set key from the animation menu next to each of the controls.

Delete Key

 delete_key_shape

N/A

Deletes the keys on the positions of all the bounding box corners (p0-p7) on the current frame.

Delete Anim

 del_anim_shape

N/A

Deletes the keys on the positions of all the bounding box corners (p0-p7) on all frames.

P0 xyz

p0

-0.5, -0.5, -0.5

Sets the x, y, and z coordinates for the p0 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P1 xyz p1

-0.5, 0.5, -0.5

Sets the x, y, and z coordinates for the p1 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P2 xyz p2

0.5, 0.5, 0.5

Sets the x, y, and z coordinates for the p2 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P3 xyz p3

0.5, -0.5, -0.5

Sets the x, y, and z coordinates for the p3 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P4 xyz p4

-0.5, -0.5, 0.5

Sets the x, y, and z coordinates for the p4 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P5 xyz p5

-0.5, 0.5, 0.5

Sets the x, y, and z coordinates for the p5 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P6 xyz p6

0.5, 0.5, 0.5

Sets the x, y, and z coordinates for the p6 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.
P7 xyz p7

0.5, -0.5, 0.5

Sets the x, y, and z coordinates for the p7 corner of the bounding box. You can also adjust these by dragging the corresponding vertex in the Viewer.

Source Box Tab

Use Incoming Bounding Box

src_use_bbox

on

By default, the node warps the bounding box of the input object. If you'd rather warp a custom bounding box, uncheck this and use the controls below to define the custom box.

Reset Source Box To Input

reset_src_shape

N/A

When Use Incoming Bounding Box is disabled, cancels any changes you've made to the custom bounding box and resets it to the original settings taken from the input.

Box

src_color

red

When Use Incoming Bounding Box is disabled, sets the color of the custom bounding box in the 3D Viewer.

Source 0 xyz

src0

-0.5, -0.5, -0.5

When Use Incoming Bounding Box is disabled, sets the x, y, and z coordinates for one of the two custom bounding box corners you can adjust.

Source 1 xyz

src1

0.5, 0.5, 0.5

When Use Incoming Bounding Box is disabled, sets the x, y, and z coordinates for one of the two custom bounding box corners you can adjust.
Display Tab
Draw Bounding Box preview_bounds off Draw the bounding box of the field if it has one.
Draw Preview 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.
