02. Creating Deformers (Curved Surface)


    Curved Surface Deformers

Creating a Curved Surface Deformer adds a resizable grid onto the part it will control. To change it's shape, you manipulate this grid to squash and stretch the part however you like, giving the illusion that it is bending on a physical surface.
That is why it is named [Curved Surface] Deformer.
This tool enables you to change the shape of parts, and stacking different deformers, especially of the face, will help you achieve a 3D effect.
The intersections of the deformer grid lines (the bezier points) will be called [Control Points] so as to not confuse them with other controllable anchor points.


 When creating a Curved Surface Deformer, you can set the number of [Conversion Divisions] and [Bezier Divisions] to create

  • Bezier Divisions
Bezier Divisions controls the number of intersection that can be edited on the deformer.
More divisions means more control over the shape, but it also means more care must be used when deforming to make sure nearby control points are not moved by accident.
Smaller deformers could have a simple 2 x 2 or even 1x 1 divisions, and bigger deformers could have more bezier divisions.

  • Conversion Divisions
Controls the deformer effect on the object during live animation, and offers more horizontal x vertical control.
Increasing the number of divisions will give the object fluid transition when animating, but too many divisions will slow down the process on slower machines.
It is advised to use a high number sparingly, and only on objects that benefit from fluid motion during live animation, such as hair and loose-hanging clothes, long accessories etc.


Below is a sample of the different settings possible for divisions





 
  Create a Curved Surface Deformer

1. Select the part of the model that you would like to add a deformer to


2. Click on [Create Deformer]



3. Enter a name, and select the [Curved Surface] button from the type of deformers list.
Set the number of Bezier
divisions and conversion divisions, or leave the default values as they are.  (please note that adding too many divisions will affect the speed of real-time calculations in applications such as games).
Press the "OK" button, you will be returned to the canvas.


4. Now the canvas has a new deformer, adjust the position and size to loosely fit the model part.














5. It is also possible to apply an existing deformer to a drawing object by selecting the model part, and in the [Edit] palette, click the drop down list of [deformer] and select the deformer you would like to apply.



6. To modify the position and size of the deformer without affecting the shape of the drawing object, CTRL+Drag the corners of the deformer.



7. Moving the corners and control points of the deformer will now modify the shape of the drawing object.




    Creating a Curved Surface Deformer in Quick Mode

1. Select the part you would like to add a deformer to



2. Click on [Create Deformer], enter a name, and select the [Curved Surface] button from the type of deformers list.
Set the number of Bezier
divisions and conversion divisions, or leave the default values as they are.
Press the "OK" button, you will be returned to the canvas.




3. Check the box "Set to the parent of the selected object (curve/image)"



4. The deformer will be created as the default parent of the current drawing object.



5. To modify the position and size of the deformer without affecting the shape of the drawing object, CTRL+Drag the corners of the deformer.





 
 
Editing Curved Surface Deformers

Dragging the mouse while holding down a hotkey on the keyboard enables you to edit the curved surface deformers without affecting the drawing object, or to affect it in a very specific way.
For more information, please refer to the following chart:
