This release is focussed mainly on optimisation and bug fixes, with significant speedups being provided by moving to a new caching implementation in Cortex 9. Behind the scenes it also contains progress towards exposing Dispatcher functionality at the user level.

Core

  • Optimised FilteredChildIterator and PlugIterator. This alone gives more than a 5% speedup in a simple Instancer benchmark.
  • Fixed serialisation of non-dynamic ArrayPlugs. This bug caused the appearance of duplicate requirements plugs on executable nodes (#580).

UI

  • Added a grid to the 3D viewer.
  • Added NodeGraph menu item for selecting objects affected by a node - accessed by right clicking on a filtered scene node.
  • Fixed several causes of zombie widgets which could cause errors at shutdown.
  • Moved the Execute button for ExecutableNodes to a prominent position in the header of the NodeEditor.
  • Added SceneWriter to the node menu. Also reorganised the Scene menu to include a File submenu, and simplified the Object menu by moving generators into the Source submenu.

Scene

  • Optimised Shader network computation - reducing runtime by 35% for typical production networks.

Arnold

  • Fixed ArnoldRender "Generate expanded .ass" mode. It was using a "-resaveop" command line flag removed from kick in Arnold version 4.0.10.0.

API

  • Added ability for Gadgets to have child Gadgets. Previously only ContainerGadgets could have children.
  • Rederived NodeGadget from Gadget rather than IndividualContainer. This allows more flexibility in NodeGadget implementations, and also better hides the implementation details.
  • Added methods for controlling Gadget visibility.
  • Rederived ViewportGadget from Gadget rather than IndividualContainer. This allows viewports to have multiple child gadgets, which paves the way for more complex views and interactive manipulators.
  • Made UI registration methods accept classes in place of TypeIds.
  • Added public GafferScene::Filter methods for specifying input scene via Context.
  • Added SceneAlgo.h with methods for querying all objects matching a filter.
  • Continued refactoring the Executable framework, in preparation for exposing it to users
    • Americanized spelling.
    • Renamed ExecuteUI to DispatcherUI.
    • Renamed ExecutableNode "dispatcherParameters" plug to simply "dispatcher".
    • Rederived SceneWriter from ExecutableNode.
    • Rederived Dispatcher from Node, to allow settings to be specified via plugs.
    • Renamed Dispatcher::addAllPlugs() to Dispatcher::setupPlugs().
    • Renamed Dispatcher::addPlugs() to Dispatcher::doSetupPlugs.
  • Added shutdown checks for zombie widgets and scripts.
  • Fixed "base class not created yet" GafferRenderMan import error.
  • Added _copy parameter to Shader::state() python binding.

Documentation

  • Improved formatting of Doxygen documentation - a brief description of each class is now shown above the detailed member documentation.

Build

  • Requires Cortex 9.0.0-a1.
  • Recent Cortex LRUCache improvements offer significant performance gains.
  • Updated default TBB version to 4.2.
