3ds Max 2013: new features of MassFX in review

with 13 comments

Autodesk and NVIDIA continue their effort to create the universal physics simulation system for 3ds Max package – it is known as MassFX.

What has changed in new MassFX version, that comes with 3ds Max 2013, in comparison to the first release? We have tried to answer this question in our review.

One of the main new features of MassFX 2013 is the addition of mCloth – cloth simulation module, which was co-developed with Autodesk. Despite the rumors, mCloth uses PhysX 2.8.4 cloth solver for underlying physical calculations.

In comparison to APEX Clothing tools in PhysX plug-ins, mCloth is clearly oriented on VFX area: “one click” set up (no need to skin the mesh and apply movement constraints, as for APEX), full collisions with MassFX rigid bodies with two-way interaction, vertex group operations (like pin or attach to object), support for dynamic and kinematic cloth, ability to bake the simulation in keyframes.

Autodesk has announced 3ds Max 2013

without comments

Autodesk has officially presented 3ds Max 2013 and 3ds Max Design 2013 – popular 3D modelling, rendering and animation packages.

Among other changes and improvements, MassFX, PhysX SDK based physics simulation solution, was upgraded with a number of new features.

Artists can now enjoy a more integrated and accurate dynamic toolset, thanks to a wide range of enhancements and additions to the MassFX unified system of simulation solvers.

Highlights are a new mCloth module that features tearable fabric and support for dynamic ragdoll hierarchies. In addition, improved constraints, better handling of pivot points, and enhanced UI readability help improve overall workflow.

Post-GDC 2012: APEX Dynamic Systems Module

with 8 comments

NVIDIA has uploaded a following video, revealing new, never seen before, module for APEX Framework, called APEX Dynamic Systems (it is still an early prototype, however).

Detailed description is not available yet, but it seems that this new module is supposed to speed up the creation process of complex dynamic actors like articulations, ragdolls and vehicles, by providing artist friendly environment, where one can easily create and tune such objects and preview their behaviour.

Post-GDC 2012: NVIDIA APEX Showcase

with 2 comments

NVIDIA has uploaded a set of demontrational videos, which were used to showcase features of NVIDIA APEX toolset, its authoring capabilities and games integrations examples at GDC 2012.

APEX Turbulence Module

We find APEX Turbulence demo particularly impressive, since particle simulation of such magnitude and complexity (scene contains up to 180 000 particles combined) is yet to be seen in games, while it can be used to create new generation of realistic smoke, dust and explosion effects.

It is good to see that this module has finally reached production stage. Turbulence is promised to be released as part of APEX 1.2

GDC 2012: enhancing games with APEX

without comments

Following presentation was held as part of GDC 2012 NVIDIA Game Technology Theather event on March 9.

Session called “Enhancing Games with APEX (Clothing, Destruction, Turbulence)” was presented by Aron Zoellner and Kevin Newkirk from NVIDIA.

Update: recording is now available on YouTube

Presentation has started with overview of APEX Clothing module using full-body clothing (tie, jacket, pants) on Bryce Wayne character from recently released Batman: Arkham City title as example. Dynamic clothing on Samaritan character was also demoed, but we had session about it at previous GDC already.

As a nice addition, few words were said about features of new clothing solver, introduced in PhysX SDK 3 (we expect it to appear in APEX Clothing 1.2):

  • Enhanced control over bending and shearing.
  • Enhanced control over high-energy dynamics.
  • Connected tapered capsule collision.

GDC 2012: dynamic, not pre-fractured PhysX destruction in real time

with 6 comments

More detailed videos of new experimental destruction engine with support for real-time fracturing, already previewed in previous demonstration, are now available.

Update: new technical demo from GDC 2013

In this video we show our new destruction prototype. Here, piec fractures pieces on the fly. There is no limit of how many times pieces can be fractured. Also, the fracture pattern depends on the impact location.

To simulate the massive amount of rigid bodies we use GRBs – GPU accelerated rigid boides.

GDC 2012: new PhysX and APEX technology revealed

with 4 comments

Gametrailers has published several videos, revealing what kind of newest additions to PhysX SDK engine and APEX Framework were showcased at NVIDIA Booth, at current GDC.

First video is showing yet experimental technology – new cloth solver and real-time fracturing.

Wooly character contains 840 000 particles simulated as 100 000 invidual strands of fur and is running on new solver that is currently under active research.

Real-time fracturing will be nice addition to the APEX Destruction module, which, currently, is utilizing only pre-fractured meshes. Fracturing happening in real-time, accordingly to impact force and point of damage application will certanly make destruction look more natural and immersive.

Update: more detailed videos of new fracturing engine.

Update #2: fur simulation technology video

GDC 2012: using IKinema with PhysX and preview of MassFX 2013

with one comment

Following presentations were held as part of NVIDIA Game Technology Theather event on March 7.

First one is called “3ds Max with MassFX” and was presented by Chris Murray from Autodesk.

Update: recording is now available on YouTube

This talk was mostly focused on features under development, that are expected to be added in future versions of MassFX, like mCloth – new clothing simulation solution.

mCloth is supposed to provide stable two-way interaction with rigid bodies, probably utilize GPU acceleration, support user-controlled tearing (through vertex selection) and include some interesting pressure simulation for balloon-like behaviour (for example, if you have holes in your mesh, balloon will deflate).

PhysX 3 Fluid Simulation Demo evolves to Fluid Sandbox

with 4 comments

Few months ago we wrote about interesting project – custom SPH Fluid simulation demo, that was using PhysX SDK 3.0.2 as physics engine and OpenGL as rendering API.

Recently, its author known as Finalspace has presented an updated version of this application, which is now called Fluid Sandbox.

Update: Fluid Sandbox 1.4.5 is up. New version is based on PhysX SDK 3.1 and features improved rendering, additional scenarios, better support for multi-core CPUs, fluid emitters and drains.

New release is named “Sandbox” for a reason – most of the data is now stored in XML format, so it is possible to customize existing scenarios (or even create new ones), edit scene and simulation properties, or add custom obstacles.

Apart from that, updated features include improved Screen Space Fluid Rendering option, new basic scenarios, more flexible settings and properly working interaction between fluid particles and rigid bodies.

As we already mentioned in our previous article, Fluid Sandbox is a great tool to play with, which functionality surpasses any other PhysX Fluid demos ever released.

You can download Fluid Sandbox from original thread at Delphi OpenGL Community forum.
