i have started working with OpenGL recently, and sorry if i have posted in wrong place.
actually i want to achieve terrain deformation at simulation run-time, right now i am using Delta3d with QT and thought to add Terrain deformation feature. Let me explain exactly what i want to doi searched bit in Google but sadly i didn't get any answers, please suggest what can be done to achieve Terrain deformation.any examples or any links will be great to start with .for ex: i have button lets say "Deform" , when i click that and click anywhere on terrain in scene that should select a vertex and pull it for certain height and surrounding vertex related to selected one should also be pulled out relatively to keep a smooth obstacle effect like a mountain.
Resultant terrain should look like below after deformation.
Thanks in advance,
