APEX SDK 1.3.2 is available

with 4 comments

Following the PhysX SDK 3.3.2 release, updated APEX SDK 1.3.2 is available for download.

Update March 2015: Bug-fixing APEX SDK 3.3.3 release is available.

Despite the minor version number, APEX 1.3.2 includes numerous additions to Destruction and Particles modules.

APEX SDK 1.3.2: Release Notes

APEX Framework 1.3.2

  • General:
    • Added NVTX profiling support for non-release builds. Traces can be captured using Parallel Nsight Analysis Tools. NVTX is supported only for Windows and Android.
  • Optimizations:
    • Added ability to change render resource lock behavior or disable locking altogether, to improve performance. The setting is per module. See NxModule::setRenderLockMode and NxApexRenderLockMode.
    • Added ability to disable potentially expensive stat collection if it’s not needed. See NxApexSDK::setEnableApexStats.
  • Fixes:
    • Fixed crash if application creates APEX SDK after already connecting to PVD.

    PhysX SDK 3.3.2 arrives, adds GPU acceleration support on Linux

    with 3 comments

    New PhysX SDK 3.3.2 release is available for download.

    Update March 2015: Bug-fixing PhysX SDK 3.3.3 release is available. Release Notes.

    Windows, Linux, OS X, Android and iOS builds are now available for free with source code.

    nvidia-physx

    Among various bug-fixes, this version also features support for GPU acceleration on Linux platform (CUDA-capable devices only) and reworked documentation.

    PhysX SDK 3.3.2: Release Notes

    GENERAL

  • Added:
    • The PhysXCommon/64.dll, nvcuda.dll and PhysXUpdateLoader/64.dll are loaded and checked for the NVIDIA Corporation digital signature. The signature is expected on all NVIDIA Corporation provided dlls. The application will exit if the signature check fails.
    • Added the PxDefaultBufferedProfiler extension for simplified SDK profile events extraction.
    • PxSceneDesc::sanityBounds allows a bounding box to be set for validating the position coordinates of inserted or updated rigid actors and articulations.
    • Linux: Now supports GPU PhysX.
    • Added set/getRunProfiled() for PxDefaultCpuDispatcher to control profiling at task level.
    • Android: Support for x86 based devices was added.
    • PxProfileEventHandler::durationToNanoseconds() added. Translates event duration in timestamp (cycles) into nanoseconds.
    • Added SnippetProfileZone to show how to retrieve profiling information.
    • Added SnippetCustomJoint to better illustrate custom joint implementation, and removed SnippetExtension.
    • Added SnippetStepper to demonstrate kinematic updates while substepping with tasks.
  • Fixed:
    • Significant revision of the user’s guide. Both structure and most content have been modified.
    • PxTask::runProfiled() now takes threadId as a parameter.
    • The static pruner now issues a performance warning in debug and checked configurations when a tree rebuild occurs and the tree is not empty.
    • PxSceneDesc::staticStructure now defaults to PxPruningStructure::eDYNAMIC_AABB_TREE.
    • Linux: Switched to shared libraries.
    • Profile zone event names changed to match function calls.
    • Overlapping read/write errors will now issue a PxErrorCode::eINVALID_OPERATION rather than PxErrorCode::eDEBUG_INFO.
    • Improved SnippetToleranceScale to better demonstrate the intended use case.
    • Increased 126 characters limit for warnings on unix platforms, 1k limit on all platforms.
    • PhysXCommon dll load within PhysX dll now respects dll name. Please see the manual’s PhysXCommon DLL load section.
    • Fixed search function of user’s guide.
    • Foundation math classes now have in-place arithmetic operators (+= etc).
  • Deprecated:
    • Indexing operators taking signed integers in PxVec3, PxVec4, PxMat33, PxMat44, PxStrideIterator have been deprecated.
