The anyHandles(), anyInputHandles(), anyKnobHandles() and doAnyHandles() functions have been modified to return an HandlesMode enum type instead of the bool they previously did. This allows more fine-grained control over whether expensive OpTree generation needs to be called.
The bool preValidate(ViewerContext* ctx, ...) function has been changed to return an enum and it now takes a PreValidateContext class pointer.
Op::memUsage() has been removed.
DD::Image::Memory::register_user() has been removed.
New Memory tracking/management functions and classes have been added to replace this.
See the Memory Management section for details on how to use this.
Specifically, similar functionality to the memory usage callbacks in Nuke 6.3 and DD::Image::Memory::register_user() can be achieved by implementing class MemoryHolder.
The getObjectCollisionGrid() and setObjectCollisionGrid() functions have been removed.
Similar functionality can be achieved by obtaining a RegularGrid via the buildGrid() function in ViewerContext.
The objectGrid() function has been removed.
Similar functionality can be achieved by obtaining a RegularGrid via the buildGrid() function in ViewerContext.
GeoReader::Description has been moved to the GeoDescription class (in DDImage/GeoReaderDescription.h).
Member variables constructor and test have been renamed to _constructor and _test respectively.
The GeoSelection class used for querying and modifying selected Geometry within Nuke has been refactored to inherit privately from the OrderedMap class to prevent tinkering with the innards of Nuke in precarious ways.
Generally, API-wise, existing functionality has stayed the same with a few additions, with a new interface ReadWriteHandle to allow more direct access to the selection index arrays.
The bool IntersectsRay(const Ray& ray, ...) function’s signature has been changed.
The void setNodeState(Node* node, ...) and ParticleNodeState* nodeState(Node* node) functions have been removed, and are replaced with a new function ParticleNodeState* nodeState(Node* node, ParticleNodeStateFactory* factory).
The void buildGrid() function has been removed. Similar functionality can be achieved by obtaining a RegularGrid via the buildGrid() function in ViewerContext.
The Vector3 average_center_and_bounds(const PointList* points, ...) function has been removed.
The RegularGrid* getGrid() function has been removed. Similar functionality can be achieved by obtaining a RegularGrid via the buildGrid() function in ViewerContext.
Several instances of the using directive have been removed from DDImage headers. This may mean you have to add namespace qualifiers to certain classes or functions where you didn’t previously need to.
