"I found some artifacts on some models and traced it back to the
external palette override feature. There are some changes in the
layout of the external record the loader have to take into
consideration.
The other fix is to remove the OF pools from the user data of the
external ProxyNode when it is no longer needed."
"Previously, the new OpenFlight plugin only allowed ext ref models to use
their own palettes. With this change, parent models can override child model
palettes with the parent palettes.
These changes are made against very current CVS (just updated about 1/2 hour
ago, eliminated conflicts, and retested before this posting).
To regurgitate what I did:
A new class, ParentPools (public osg::Referenced), is created when an ext
ref record is parsed, and it is populated with any parent model pools that
should override the child model pools (according to bits in the ext ref
record). The ParentPools object is then set as UserData on the ProxyNode
corresponding to the ext ref.
When the ReadExternalsVisitor hits the ProxyNode, it takes its UserData and
sets it as UserData in the Options parameter to the osgDB::ReadNode call,
which then read the ext ref model. In the course of parsing the Options
string, ReaderWriterFLT also looks at the Options UserData and sets the
parent pools in the Document class accordingly.
When palette records are encountered while loading a file, they are ignored
if the corresponding pool was set by the parent.
Thanks to Brede for consulting with me on the implementation.
"
From Robert Osfield, remapped Paul Martz's changes to Pools.h and PaletteRecords.cpp w.r.t texturePatternIndex being a in16, and converted a char* string to a std::string.
changes to this plugin that aren't in current CVS yet -- this change is
based on current CVS, not our changed files.)
This changes how shader palette records are parsed to support GLSL per the
OpenFlight 16.1 spec. Existing functionality for 16.0 files is preserved.
The change to Document.h simply adds an enum for VERSION_16_1."
"- Replaced some member attributes with local variables in Face record.
- Multitexture support in Vertex class.
- Renamed VertexList to VertexListRecord (VertexList is now a Vertex array)
- new Mesh (with reserved field at offset 12, thanks to Paul Martz)
- new LocalVertexPool
- new MeshPrimitive
- Use ProxyNode for externals.
- Local cache for externals"
that removeChild(Node*), removeChild(uint) and equivilant Geode methods are
now inline methods, not designed to be overriden, and seperated out the
multiple remove method to be called removeChildren(uint, uint) which is
now the only virtual method. There removeChildren is now the method to
override in subclasses.
This reorganisation requires some call code to be rename removeChild usage
to removeChildren.
