0.17.0.0

This release brings several major features in addition to the usual enhancements and bug fixes. Of particular interest are the addition of a basic keyframing system, support for using OSL expressions alongside the existing Python expressions, and several new image processing nodes exposing OpenColorIO functionality.

Core

• Added Animation node, providing basic support for keyframed animation.

• Added frames-per-second support to Contexts, to map between frames and a time in seconds.

• Expression

  • Fixed bug when identical expressions acted on different plug types.

  • Added support for calling context.getTime().

  • Added support for calling context.getFramesPerSecond().

  • Fixed bugs when a plug or node is renamed.

  • Fixed bugs when manually disconnecting an output or input of an expression.

  • Improved error reporting in the UI.

• Fixed InputGenerator backwards compatibility bug introduced in 0.16.0.0.

• Box

  • Promoting a plug now properly copies plug metadata (#1468).

• Plug

  • Fixed rare crash during dirty propagation.

  • Fixed bug in child connection tracking behaviour.

UI

• NodeEditor

  • Plug context menus

    • Added keyframing menu items for numeric and bool plugs.

    • Added Lock/Unlock meu items.

    • Added menu item for creating an OSL expression.

  • Tool menu

    • Added “Revert to Defaults” menu item.

• NodeGraph

  • Added right click menu items for reordering plugs on Boxes.

  • Fixed bugs triggered by the dynamic hiding and showing of plugs via the UIEditor.

• Dot

  • Added optional labels. These can be derived from the dot node name or the upstream node name or may be specified directly.

• Shader loading dialogues

  • Added bookmarks.

• Viewer

  • Fixed bug which could mean the camera would move unexpectedly even when look-through mode is not enabled.

  • Fixed OpenColorIO configs.

• UIEditor

  • Fixed renaming of empty user sections.

  • Prevented renaming of section to invalid names like “”.

  • Added default Settings section.

  • Fixed presets UI to update values when the selected preset changes.

  • Ignores user plugs on box nodes.

• Box

  • Added default Settings section.

  • Disabled plug addition button in User section.

• Fixed bug which could cause the display of corrupted icons.

• ShaderSwitch

  • Fixed UI to provide access to each input rather than just the array input as a whole (#1461).

• Numeric fields

  • Ensured that keyboard-nudged numbers have an extra 0 added as necessary to ensure that the same digit is always being modified.

Image

• New OpenColorIO nodes

  • LUT

  • CDL

  • DisplayTransform

• ImageWriter

  • Added file format options.

  • Made sure OIIO queries for nchannel and alpha support are respected.

• Merge

  • Fixed artifacts when the data windows differ between layers.

  • Fixed crash.

• Resize

  • Fixed artifacts when upsizing with the sinc filter (#1457).

• Changed convention for image bounding boxes to specify that the maximum coordinates are exclusive (outside the box).

• Fixed Crop UI for images with the default format.

• Resample

  • Fixed incorrect input sample region.

Scene

• Fixed loading of UnionFilters from Gaffer 0.15.0.0 (#1474).

• Fixed loading of FilterSwitches from Gaffer 0.15.0.0 (#1474).

• Attributes are now output to the renderer before shaders at the same location. This works around a bug in 3delight’s shader construction.

• Fixed crash when loading sets from an empty SceneReader.

• Added support for frames-per-second to SceneReader, AlembicSource and SceneWriter.

OSL

• Added support for using OSL as a general purpose expression language.

Cortex

• Fixed issue where non-ValuePlugs were not syncing during setPlugValue().

• Fixed OpHolder node summaries.

API

• Expression

  • Redesigned API to better support multiple languages.

• Context

  • Added “framesPerSecond” variable and time accessors.

• Metadata

  • Added nodesWithMetadata() and plugsWithMetadata() methods.

• StandardNodeGadget

  • Removed orientation constructor parameter. Use metadata instead.

  • Added dynamic nodule reordering controlled by metadata.

• ScriptNode

  • Fixed undo merging for CompoundNumericPlugs (#422).

• Plug

  • Made setFlags() undoable.

• PlugLayout

  • Ignore custom widgets with type “”. This allows a widget inherited from a base class to be removed by a derived class or instance metadata.

• Removed UserPlugValueWidget.

• Added UserPlug namespace.

• Deprecated use of arbitrary Widget constructor keyword arguments for auto-parenting. The parenting argument should be used instead.

• Image

  • Renamed GafferImage::OpenColorIO to ColorSpace.

  • Changed convention for image bounding boxes to specify that the maximum coordinates are exclusive (outside the box).

    • Added image window utility methods to assist with this change.

  • Added OpenColorIOTransform abstract base class. This makes it easy to implement nodes whose processing is performed via OpenColorIO.

  • Sampler

    • Remove sample window accessors.

    • Deprecated constructor taking a filter.

• Added NumericWidget.valueToString() method.

Incompatibilities

• Redesigned expression API to better support multiple languages.

• Changed convention for image bounding boxes to specify that the maximum coordinates are exclusive (outside the box).

• NodeGadget

  • Added noduleAddedSignal() and noduleRemovedSignal().

• StandardNodeGadget

  • Removed orientation constructor parameter. Use metadata instead.

• GraphComponentWrapper

  • Improved constructors to allow any type to be passed to the single argument constructor.

• Removed UserPlugValueWidget.

• Deprecated use of arbitrary Widget constructor keyword arguments for auto-parenting. The parenting argument should be used instead.

• Renamed GafferImage::OpenColorIO to ColorSpace.

• Sampler

  • Remove sample window accessors.

  • Deprecated constructor taking a filter.
