Generate force fields from your keyboard, pick object vertices to be fixed and pull on object vertices with mouse picking to play around with the model deformable objects. Customize the deformable object's behaviour by tweaking parameters in the imgui menu.
While holding down the shift key, press the left mouse button while hovering your mouse cursor on the object to make the pointed-to object's vertex fixed (if it was free) or free (if it was fixed) in space.
While holding down the ctrl key, press the left mouse button when your mouse cursor points on the object and hover your mouse cursor around in the direction you want to pull the pointed-to object's vertex in space.
Generate force fields in the up, down, left, right, forward and backward directions from your keyboard using, respectively, the i, k, j, l, space and b keys.
Explanations to come.
