0.33.0.0

Breaking Changes

• Image :

  • ImageWriter : Defaults to writing all channels instead of just RGB (#2021).

  • DeleteChannels : Changed channels plug default to “” (#2021).

  • ImageStats : (#2018)

    • Defaulted to sampling A in addition to RGB.

    • Changed interpretation of ImageStats channels to simply be a list of 4 channels that correspond directly to the output RGBA plugs. Behaviour is unchanged apart from situations where an incomplete or ambiguous channel mask was in use.

  • Warp : New API (#1980).

    • Engine no longer depends on channelName.

    • Derived classes no longer responsible for computing inputWindow.

• API :

  • Renamed UndoContext to UndoScope (#2049).

  • Removed Nodule::registerNodule() overload which took a plug name regex. Use “plugValueWidget:type” metadata instead (#2045).

  • Added private data member to PerformanceMonitor (#2016).

  • Added createUStrings argument to OpenImageIOAlgo::DataView constructor (#2040).

  • Removed ChannelMaskPlug. Use a StringPlug and StringAlgo::matchMultiple() instead (#2021).

  • Renamed renderer backends to “Arnold” and “Appleseed” (#1994).

  • Added virtual method to Style class (#2051).

Features

• Scene :

  • Added light linking (#1985)

    • Light links are specified as set expressions using the StandardAttributes node.

    • Currently only supported in the Arnold renderer backend.

  • Added “scene:renderer” context variable which can be used to query which renderer a scene is being generated for (#1994).

  • SetFilter : Added support for using arbitrary set expressions instead of just a single set (#2052).

  • Added RotateTool for interactively rotating objects in the viewport (#2051).

  • Added MeshTangents node to compute Tangent & Binormal primitive variables on a mesh (#2028).

• Image

  • Added Median node (#2022)

  • Added Mix node (#2026)

  • Added CopyChannels node (#2006)

  • Improved support for images with multiple layers : (#2018, #2021)

    • Added layer selector to image viewer

    • Added improved layer/channel selection to many nodes

    • Added ability to use wildcards to select channels to process

  • Added colorSpace plugs to ImageReader and ImageWriter (#2004).

• Box : Added BoxIn and BoxOut nodes to improve the visualisation of promoted plugs within the NodeGraph (#2011).

• TaskList : Added “sequence plug” (#2044).

• Improved GafferImage performance (#2016, #2031).

• OSLShader : Added support for vector->color connections (#2042).

• Expression : Added context menu for inserting common functions and node bookmarks (#2039).

• Stats app : Added performance monitor summary (#2016).

• Merge : Added min and max modes (#2027).

• Grade : Added support for grading alpha channel (#2023).

• Warp : Improved filtering (#1980).

• Added more string matching features #2015 :

  • [A-Z] style character classes

  • ? to match any character

  • ‘’ to escape a subsequent wildcard

• Added mode and units settings to the UVWarp node, and renamed it to VectorWarp (#2014).

• StandardNodeGadget : Added more metadata support (#2011)

  • “icon” to add an icon.

  • “nodeGadget:shape” to choose a rectangular or oval shape

Fixes

• Shader : Fixed bug when assigning a disabled shader with pass-through defined (#2025).

• OSLCode : Fixed string length menu item (#2039).

• Expression :

  • Fixed string context variable comparison bug (#2040).

  • Protected context from modification (#2010).

• ErrorDialogue : Fixed bug in message handling code (#2030).

• StringAlgo : Fixed bug in matchMultiple() (#2015).

• Switch/Dot : Fixed plug colours in NodeGraph (#2008).

• Transform/Resize : Fixed sinc filter (#1980).

• Fixed export of color/vector plugs from Boxes (#2012).

• Resize : Stopped resampling when only pixel aspect ratio is changed (#2007).

• Fixed crash in viewport mouse handling (#2005).

• Fixed Node Reference link in help menu (#2002).

• Fixed framing of lights in the Viewer, by giving them a default bounding box (#2054).

API

• MetadataAlgo :

  • Added “childNodesAreReadOnly” metadata. This makes it possible to make the internal nodes of a node read-only, while still allowing the external plugs of the node to be edited (#2048).

  • Added functions for bookmarking nodes (#2039).

  • Added childAffectedByChange() overload for Node changes (#2029).

  • Added copy() function (#2003).

  • Added copyColors() function (#2008).

• NoduleLayout : Added support for custom Gadgets to be specified via metadata (#2043).

• ImagePlug :

• Context management (#2041, #2016) :

  • Added Context::EditableScope utility class. Use this instead of the now-deprecated Context::Borrowed copy contructor.

  • Added PathScope/SetScope/GlobalScope utility classes to ScenePlug

  • Added GlobalScope/ChannelDataScope utility classes to ImagePlug.

  • Added FilterPlug::SceneScope utility class.

• Added V2iVectorDataPlug (#2031).

• NodeGadget :

  • Added support for “nodeGadget:type” metadata to control the type of gadget created by a node (#2029).

• GraphGadget : Added support for dynamically changing “nodeGadget:type” metadata (#2029).

• Added ChannelPlugValueWidget (#2026).

• Added RGBAPlugValueWidget (#2018).

• ImageGadget : Added methods for selecting which channels to view (#2021).

• ImageAlgo : Added channelNames() and layerNames() functions (#2019).

• Added SetAlgo namespace with methods for evaluating set expressions (#1985).

• PathMatcher : Added intersection() method (#1985).

• Added FilterAlgo namespace with methods for doing filtered image sampling (#1980).

• SceneAlgo : Added render adaptor API. This provides a simple registry of SceneProcessors which will be used internally within Render nodes to perform just-in-time adaptations of the scene for rendering (#1994).

• PlugAlgo : Added plug promotion methods (#2003).

• Added RotateHandle class (#2051).

Build

• DEBUG build option now also disables optimisations (#2009).
