New Miarmy 1.2 plug-in utilizes PhysX SDK 3.1

without comments

Basefount has announced release of Miarmy 1.2plug-in for Autodesk Maya that is capable of behavioral animation, crowd simulation, physics calculation and rendering.

Amond other features, physics engine in Miarmy 1.2 is now based on PhysX SDK 3.1 (in previous releases – 2.8.4), which provides faster and more accurate rigid body physics simulation even with high number of complex jointed objects.

In addition, usage of new PxCloth solver allows “100 times faster” simulation of cloth and clothing assets.

With new PhysX 3.1 Engine, The limit on the number of dynaimc agents is gone. On an average home PC, one can easily create a scene with more than 5,000 agents enable dynamics which contains more than 85,000 RBD objects and 80,000 dynamical joints. The cloth simulation will became almost real-time.

NVIDIA APEX 1.1 is available, GPU Rigid Bodies feature included

with 14 comments

NVIDIA has released APEX SDK 1.1 (Build 112), next version of NVIDIA APEX – scalable dynamics framework, oriented on complex physical simulations.

Update: APEX 1.2 is available

In comparison to APEX 1.0 Beta, new version includes many bugfixes, several additions to underlying framework and various new features, like ability to calculate rigid body physics on GPU.

APEX 1.1 contains only Destruction and Clothing modules, and is still based on PhysX SDK – first version with PhysX 3 support is going to be APEX 1.2 (that is supposed to be released in a few months).

We must also note that APEX 1.1 requires corresponding authoring tools – PhysXLab 1.1 and 2.71 DCC plug-ins.

NVIDIA APEX SDK 1.1 is available for download at Developer Support Center.

If you are experiencing trouble with registration of PhysX Developer account, please refer to our registration guide.

Release Notes:


New Features

  • GPU Rigid Bodies: the NxModuleDestructible has settings to enable calculation of Rigid Body physics on GPU.

Highly anticipated feature. While using same assets and same settings, GPU Rigid Bodies are showing significantly higher performance – 70 fps for 5000+ rigid body chunks on single GTX 580 vs 10 fps on Core i7 2600K.

One-way interaction with dynamic CPU actors is also supported (via transfer of momentum). GPU accelerated rigid body physics requires NVIDIA driver 270.81 or later, PhysX 2.8.4 RC6 or later and a CUDA capable GPU.

Pre-GDC 2012: PhysX and APEX presentations overview

without comments

NVIDIA has revealed presentations schedule for Game Developers Conference 2012 (GDC 2012), taking place on March 5-9 in San Francisco.

As usually, certain talks will be demonstrating latest advances in PhysX and APEX technologies. Let’s take a look:

March 7th, Booth #1424

3dsMax with MassFX

11:00am - 12:00pm. Chris Murray, Autodesk

Autodesk’s implementation of MassFX within 3dsMax will show you just how easy the workflow is for rigid body dynamics and how versatile to the tool can be. Additionally, Autodesk will be giving a technology preview of some aspects of MassFX currently being experimented with in 3dsMax.

IKinema IK for Combining Physics and Animation in Maya

2:00pm - 3:00pm. Alexandre Pechev, IKinema

IKinema is a production-proven solution for animating with inverse kinematics (IK) in Maya. Come see how we combine IKinema IK with NVIDIA’s PhysX Plugin for Maya to produce animations that can capture a character’s intent and physical simulation at with an improved speed and accuracy over handmade animations. Dressing the character with APEX Clothing can add even more dramatic physical effects and secondary motion to your film or game.

MassFX: what is coming in future versions of 3ds Max

with 4 comments

As always at the beginning of the year, Ken Pimentel (Director of Visual Communication Solutions within Autodesk) has revealed some details about new features and capabilities of upcoming versions of 3ds Max.

Few words were said about MassFX - PhysX SDK based physics simulation solution, introduced in 3ds Max 2012.

We introduced MassFX and mRigids (based on PhysX and our partnership with Nvidia) in 3ds Max 2012. It was a start on our march to a more unified dynamics experience. We’ve continued that effort with Nvidia and we think you’ll be pretty pleased with the results in general. We’re not done, but definite progress in the right direction, we hope you’re pleased with it.

“Results” will include, at least, the addition of mCloth module for cloth simulation (as revealed at SIGGRAPH 11) and forcefields functionality through standart Force objects (as you can notice from a “teaser” video below).

Fluid Simulation demo with OpenGL and PhysX SDK 3.0

with one comment

Very interesting PhysX Fluid Simulation demo was revealed by a user Finalspace on German Delphi OpenGL Community forum.

Update: new version is available.

Written from scratch on C++, based on PhysX SDK 3.0.2 and OpenGL, this demo is showcasing Smoothed Particle Hydrodynamics (SPH) fluid simulation in a basic environment.

However, the amount of options is appealing – you can choose from various scenes, change fluid parameters, add rigid bodies or more particles (up to 262 000), apply forces to the fluid, switch rendering modes – PhysX Fluid Simulation is a fully functional playground, more advanced than original PhysX Fluids demo from NVIDIA.

You can download PhysX Fluid Simulation v 1.2 from original thread.
