Voronoi Fracture and Shatter Lab Tests – Blender & Bullet Physics

Phymec is making some cool physics tools for Bullet Physics and Blender to enable some awsome fracture and destruction effects. Two awesome videos showing this off have been uploaded to YouTube. The first shows off the creation of the fracture objects in Blender and the newer video is an awesome collection of fracture objects being destroyed. Check them out below and check out his YouTube page for more awesome videos. This is some pretty awesome stuff. I can’t wait until we see this level of destruction and physics in games. Imagine Battlefield 3 with every objects being destructible like this.

All scenes rendered using the 100% OpenCL (xPU) accelerated SmallLuxGPU v2 (PathGPU2) render engine in SLG Live! mode, typically @ 20 secs/HD frame, no delay between frames. Only de-noise in post.
Glass on ground flicker rendering issue is likely simply due to coincident surfaces; unfortunately I didn’t notice until after it rendered, sorry.
(BTW David Bucciarelli has created a real-time OpenCL path tracing game, check it out: http://www.youtube.com/watch?v=Dh9uWYaiP3s)

All done on the same old home PC running Windows 7 64-bit on Intel i7 720 CPU and two AMD HD4890 GPUs.

Created using Open Source Software:
Blender 2.6: http://www.blender.org

Bullet Physics in your Web Browser

It looks like physics in the web browser is here to stay. We just posted about how XML3D Physics will bring realistic Physics to Web browsers now i just came across this cool demo showing off Bullet Physics working inside a web browser in this case Chrome 15+ check it out here. Hopefully soon we start to see some cool browser based games that implement this technology.

The Native Client module executed in this page runs a basic C++ Bullet Physics simulation.

Use the mouse wheel for camera zoom and left mouse button to pick and drag objects. The test embeds a Blender 3D .blend file and it can also load a local .blend file. This is an unmodified version of the Bullet C++ library using the premake build system. See the source code at http://github.com/erwincoumans/experiments.

Check in the Chrome “About Box” that you are using version 15 or later (if not see http://www.chromium.org/getting-involved/dev-channel)

Blockmania Minecraft-like open source project Uses Bullet Physics

We have posted before about some cool Minecraft Physics mods like the Minecraft with jBullet Physics and the concept video showing off Minecraft + Bullet Physics which are really cool. Now Benjamin “begla” Glatzel has started working on a new “Minecraft-like open source project,” that has implemented Bullet Physics for some cool physics effects on the individual blocks. Check out the video below showing it off and be sure to check out the official Blockmania website.

From the Bloackmania website:

Blockmania is an open source project started by Benjamin “begla” Glatzel to research procedural terrain generation and efficient rendering techniques in Java using the LWJGL. The engine uses a block-based voxel-like approach as seen in Minecraft.

Momentum 2.5 Dynamic Fracturing Physics Tech Preview

Now this is pretty cool. There are some new technology preview videos out showing off the different physics features of the new Momentum 2.5 engine which is a high speed multi-physics simulator that uses Bullet Physics and can be used with Autodesk Softimage 2010, 2011 and 2012. Pretty cool stuff. Find out more about it at the Exocortex Technologies Momentum page and check out the video below showing off Fracture physics.

This video demonstrates the new dynamic fracturing options for the Momentum 2.5 update.

Exocortex, in collaboration with Helge Mathee, is pleased to announce that Momentum 2.0, the ultimate high speed multi-physics simulator, is now immediately available for Autodesk Softimage 2010, 2011 and 2012.

Exocortex Momentum 2.0, because it relies on the industrial strength Bullet physics framework, provides robust support for Rigid Bodies, Soft Bodies, Cloth, Ropes, Constraints, Interactions and Attachments.
