For bicubic and extended bicubic surfaces, there are extra controls available in the Vertices tab.
- Subdivide button
-
- Position X, Y, Z fields
-
Move selected surface points along the X,Y or Z-axis. Hold down
Ctrl and select surface points to position them.
- Rotation X, Y, Z fields
-
Rotate selected surface points along the X,Y, or Z-axis. Hold down
Ctrl and select surface points to rotate them.
- Scale X, Y, Z fields and Prop button
-
Scale selected surface points along the X,Y, or Z-axis. Hold down
Ctrl and select surface points to scale them. Enable Prop to scale surface points proportionally.
- Magnet button
-
Enable to transform selected vertices and tangents numerically. Use in conjunction with the Magnet Transformation box. See
Transforming Multiple Points.
- Magnet Transformation box
-
Select the type of transformation to use when Magnet is enabled.
- Home button
-
Resets the postion of the magnet curve after panning.
- Undo button
-
Undoes a change to the Magnet Curve Editor.
- Reset button
-
Resets the Magnet Curve Editor.
- Reference Point X, Y, Z fields
-
Set the location of the reference point. Use the reference point to constrain the rotation and scaling of an individual or
group of vertices.
- Shape Channel button
-
- Sort button
-
Enable to sort non-flat surfaces where overlapping transparent regions are causing artefacts. By default, the reference point
appears in the centre of the extended bicubic. When unselected, the reference point is green.
- Auto Adjust button
-
Scales adjacent tangents automatically. Auto Adjust creates a smooth curve between points in the deformation. If you want
to work on a specific area of the image without affecting other tangents, disable Auto Adjust.
NoteIf you move a tangent explicitly, it is not affected by Auto Adjust. Click Reset Points or Reset Shape so that the tangents
will be affected by the Auto Adjust mode.
- 3D Handles button
-
Enables Z buffering of the vertices. By default, the vertices are always visible, regardless of their position in Z space
in relation to other media.
- Reset Selection box
-
Select Reset Shape to reset the surface shape handles to their default position. The handles are reset in the current frame
only. If Auto Key is enabled, a shape key is added at the current frame. Select Reset Points to reset selected points on the
surface.
