Adaptive Tearing and Cracking of Thin Sheets, SIGGRAPH 2014

SIGGRAPH 2014 -- Tobias Pfaff, Rahul Narain, Juan Miguel de Joya, and James F. O'Brien
Project page: graphics.berkeley.edu/papers/P...
Abstract:
This paper presents a method for adaptive fracture propagation in thin sheets. A high-quality triangle mesh is dynamically structured to adaptively maintain detail wherever it is required by the simulation. These requirements include refining where cracks are likely to either start or advance. Refinement ensures that the stress distribution around the crack tip is well resolved, which is vital for creating highly detailed, realistic crack paths.
The dynamic meshing framework allows subsequent coarsening once areas are no longer likely to produce cracking. This coarsening allows efficient simulation by reducing the total number of active nodes and by preventing the formation of thin slivers around the crack path.
A local reprojection scheme and a substepping fracture process help to ensure stability and prevent a loss of plasticity during remeshing.
By including bending and stretching plasticity models, the method is able to simulate a large range of materials with very different fracture behaviors.

Closest I've seen was The Force Unleashed back in 2007, they had amazing glass shattering and used it very few times in the game :/ They had metal bending, wood fracturing, it was awesome. I emailed the tech company behind it and it's supposedly used in Quantum Break and may be coming to more things again (it wasn't used after the force unleashed but was used in films)

@TheCatOfWarCSGO 8 жыл бұрын

But was force unleashed's fracturing prerendered animations or realtime simulations? Because I'd be very surprised if it were the latter all those years ago

@jimmysgameclips 7 жыл бұрын

This is the thing, I'm fairly sure they were the latter as well as the prior. Some of those simulations happened on the fly and it was amazing, back in 2007 too! I still think the tech is witchcraft... If you don't want to play the game and see the odd places it was used then you can see the tech demo with the small objects being thrown at the piece of wood, you can see it happening on the fly ;)

@RussianPowerful 7 жыл бұрын

devices aren't ready for realistic physics (which already exist) as it requires a lot of processing power and would overwhelm most computers if it were added to games. Nvidia PhysX has been around for years and is far more primitive than what is shown in the video yet not many games use it as it lags on a lot of computers.

@jimmysgameclips 7 жыл бұрын

Many older computers maybe, even mine is lagging behind but I can run plenty of physx operations no problem. They used to have a dedicated card for physx but now it's done on the GPU and that's not a problem anymore. Nvidia Funhouse is a good example of this because it's doing it on a complex level but whilst rendering in VR. As I say though the DMM they were doing on the PS3 back in 07 was amazing
