Release Notes

Blast™ SDK 1.0 (24-Feb-2017)

New Features

• Serialization enabled for XBoxOne

Changes

• tclap, imgui, moved to Packman package
• Models and textures for the sample application have been moved to Packman
• Packman packages with platform-specific sections have been split into platform-specific packages
• Improvements to fracturing tools
• TkJoint events no longer contain actor data
• API cleanup:
  • NvBlastActorCreate -> NvBlastFamilyCreateFirstActor
  • NvBlastActorRelease -> NvBlastActorDeactivate
  • NvBlastActorDeserialize -> NvBlastFamilyDeserializeActor
  • Functions that operate on an object start with NvBlast[ObjectName]
  • Functions that create an object purely from a desc start with NvBlastCreate
  • Functions that get scratch start with NvBlast[Object]GetScratchFor[functionname], etc.
  • Object functions take the object as the first input parameter (non-optional output parameters always come first)
  • Removal of NvBlastCommon.h
• More consistent parameter checking in low-level API
• NvBlastAlloc and NvBlastFree functions have been removed. Blast low-level no longer does (de)allocation. All
• Memory is passed in and managed by the user
• All Blast low-level functions take a log (NvBlastLog) function pointer (which may still be NULL)
• Authoring tool now handles FBX mesh format
• Constructor for TkAssetDesc sets sane defaults
• Sample uses skinning for the 38k tower, for perf improvement
• Further optimzations to sample, including using 4 instead of 2 CPU cores and capping the actor count at 40k
• Linux build (SDK and tests)
• Renamed TkJointUpdateEvent::eventSubtype -> TkJointUpdateEvent::subtype
• "LowLevel" extension renamed "ConvertLL"
• Renamed TkEventReceiver -> TkEventListener

Bug Fixes

• Can change worker thread count in CPU dispatcher
• TkJoints created from the TkFramework::createJoint function are now released when the TkFramework is released
• Various fixes to unit tests
• Crash fix in CPU dispatcher
• Returning enough buffer space to handle hierarchical fracturing cases

Known Issues

• Serialization requires documentation

Blast™ SDK 1.0 beta (24-Jan-2017)

New Features

• TkFamily serialization
• Versioned data serialization extensions for both low-level and Tk, based on Cap'n Proto
• TkJoint API, can create joints at runtime, attachments to Newtonian Reference Frame supported
• CMake projects
• PackMan used for dependencies
• Per-bond and per-chunk health initialization
• XBoxOne and Windows support for perf zones
• Timers in Tk
• Stress solver (automatic bond breaking)
• ExtPx asset serialization, combined TkAsset + PhysX collision meshes (.bpxa files)

Changes

• Material API simplified (NvBlastProgramParams)
• Nv::Blast::ExtPhysics renamed Nv::Blast::ExtPx
• Various small changes to the low-level API (function renaming, argument list changes, etc.)
• Extensions libraries reconfigured according to major dependencies and functionality:
  • Authoring
  • Import (depends on PhysX and APEX)
  • PhysX (depends on PhysX)
  • Serialization (depends on PhysX and Cap'n Proto)
  • Shaders
• Source folder reorganization: low-level, Tk, and extensions all under an sdk folder

Removed Features

• TkComposite objects. Composites may be created using the new TkJoint API in the TkFramework

Known Issues

• Serialization requires documentation

Blast™ SDK 1.0 alpha (21-Oct-2016)

Known Issues
