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.

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).

2.7 PhysX plug-in for 3ds Max comes with SDK 3.1 support

with 3 comments

Next major release of DCC PhysX plug-in for 3ds Max has arrived.

New 2.70.1028.1400 PhysX plug-in for 3ds Max (2009 – 2012, 32- and 64-bit) just have landed on download page at Developer Support Center.

Update: 2.7 PhysX plug-in for Maya is also available

UPDATE: 2.71 PhysX plug-in for 3ds Max is released

Additionally, updated 2.61.1028.0930 PhysX plug-in was released for 3ds Max - it includes minor bug-fixes for 2.61 version.

2.7 PhysX plug-in for 3ds Max – New Features Overview:

  • General: Additional PhysX SDK 3.1 solver

Plug-in now features two different simulation engines – PhysX SDK 2.8.4 and new PhysX SDK 3.1, with an option to switch between them seemlesly, without necessity to restart 3ds Max.

Providing same simulation quality as SDK 2.8.4, SDK 3.1 solver is noticeably faster, especially in specific scenes which contain composite meshes with complex concave geometry.

As a test, we’ve measured a time that is needed to simulate 200 frames of “Chainmail” scene (430+ composite rigid bodies), in a viewport. As you can see, in this case SDK 3.1 solver is ~40% faster.

Notes: #1 APEX Clothing is not yet supported by SDK 3.1 engine.

#2 Current SDK 3.1 implementation has limited contact buffer, so it is not recommended to use it with large number of objects.

  • Fixed order of rollout menus.
  • Very small objects used in Composite mesh generation no longer cause a program error.
  • Changing the high-velocity collision minimum speed value now works correctly.
  • The Sleep setting in the World tab no longer causes a MaxScript error.
  • An nvpx.ExportPhysXScene error dialog has been updated to be easier to understand.
  • Bake now works when the scene contains Bipeds.
  • Having the Dynamics Explorer or Scene Explorer open no longer negatively affects previewing the simulation.
  • Remove Skeleton now removes all Kinematic Skeletons, not just the first one selected.
  • Calculate At Current Frame now works correctly.
  • The Rigid Body modifier UI no longer redraws multiple times when opening.
  • The inflation value in the Multi-Editor now supports negative values for convex mesh types.
  • Selecting and moving MassFX constraints now support the type-in transform.
  • Using a Plane with box mesh type now simulates with the correct collision mesh shape.
  • You can now Undo the Convert To Custom Mesh function.
  • Rigid body collisions now behave correctly with back facing geometry.
  • Undo now works after grouping bones in a kinematic skeleton.
  • The MassFX SDK now correctly supports contact reports.
  • Creation of a new mesh in MassFX rigid body can now be undone.

It was also mentioned that remaining issues, like incompatibility with PhysX engine in Thinking Particles plug-in, will be solved in upcoming hotfix.

Siggraph 2011: The Latest Advances in NVIDIA PhysX and APEX Technology

with 2 comments

Autodesk has published a recorded video of a presentation – “The Latest Advances in NVIDIA PhysX / APEX Technology” – that was performed by Daniel Horowitz, engineering manager for PhysX dev. tools in NVIDIA,  at Siggraph 2011.

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

This presentation is covering such topics as design principles of PhysX and MassFX plug-ins, relationship between those tools, and is also giving an overview on APEX Clothing authoring process and upcoming features.

Some interesting facts:

  • APEX Destruction functionality will be added to PhysX plug-ins in the future. It was also mentioned, that it will be possible to use to use 3d party tools for fracturing (not only default solution in PhysXLab) and also tweak graphical and physical meshes separately.
  • Next release – PhysX plug-in 2.7 will support PhysX SDK 2.8.4, PhysX SDK 3.1 and APEX 1.1
  • APEX Softbodies module was mentioned.
  • Contact Layers feature (basically, collision filtering) will be added in 2.7 plug-in for Maya, and 2.x plug-in for 3ds Max.
  • Patner integration program. For example, PhysX based rigid bodies from Particle Flow plug-ins will be able to interact with MassFX rigid bodies.
  • mCloth module will be based on ClothFX plug-in from Size8Software, but it will fully interact with MassFX rigid bodies, ragdolls, atachments and so on (nice solution to keep PhysX cloth and APEX focused on clothing simulation for games only).

It was promised that new 2.7 PhysX plug-ins will arrive shortly, in a few weeks, so keep an eye on our website for a full review.
