EvalVectorField - Editing

 
selected EvalVectorField

Field object are used to deform brep objects. You should not try to render it. Field objects are completely programmable, you can write you own field.

 A field is a vector field. It exists only inside a volume. In the editor you will se a solid object ( like a box ) and inside two curves, each of a different color. One is the curve before to apply the field on it, the other the same curve after to apply it.

 You can move a field object like any other object, you can translate, rotate, scale it. To apply it, select a brep object ( click on it with left button of the mouse ) the press `f' key. You must choose which field object apply ( you may have more that one in your layer).

 Field will be applied only to control points that are inside the field volume, so you can change only a portion of an object.

 It is better that you use brep object with inline models.

 In directory "Library\field" you can find some predefinite fields:
 

  • hammer
  • lhammer
  • bend
  • taper

  •  

    Every field can be customized with same specific parameters ( different from field to field ), which modify its behaviour. You can change them with Edit|Object|Modify command.

     If you want to modify a field variable, choose it in the listbox, then click the "update" button to see the value of the variable and the range (from,to). To change a variable value use "change" button.
