With this PR we refactor `StringUtils::replaceAll` to accept `string_view` as suggested in a code comment. In addition, while we are touching this rebuild happy file, we slim it down a bit by moving a few sparingly used functions elsewhere.
This PR removes dummy serialisers for `StateSetUpdater`, `NodeCallback` and the respective `META` macros that trigger serialisation requirement here.
`StateSetUpdater` and `NodeCallback` are just base classes that can not be used on their own, so there is no need to incorporate them into serialisation. These changes might have minor effects on derived classes that forget to override `className()`, `libraryName()` through `META`, but it makes hardly a difference to now serialise such classes as a dysfunctional `osg::Callback` instead of a dysfunctional `SceneUtil::NodeCallback`.
This PR removes unneeded `lowerCaseInPlace` calls in in a hot path of `objectpaging.cpp` that are no longer necessary after PR #3197. In addition, I have been informed that these changes should by coincidence address a compiler specific compilation error we currently experience.
We currently apply a strange algorithm to `LightManager::mStateSetCache`. For some reason this algorithm inserts hashed keys into `std::map` in a way that fails to handle hash collisions and exhibits worse lookup complexity than `std::unordered_map`. With this PR we just use `std::unordered_map` here.
This PR aims to start addressing `ESM` design issues that have silenced errors we incorporated into groundcover `ESM` loading approaches.
- We move the resolution of `parentFileIndices` from `ESMStore` to `ESMReader` as suggested in a `TODO` comment.
- We improve a highly misleading comment which downplayed the significance of `parentFileIndices`.
- We document important preconditions.
- We move a user facing error message to the highest level and improve its context.
- We remove an inappropriate `setGlobalReaderList` method. We now pass this reader list into the method that requires it.
- We remove a thoroughly pointless optimisation of `Store<ESM::LandTexture>`'s construction that has unnecessarily depended on `getGlobalReaderList`.
There should be no functional changes for `master`, but this PR should remove an issue blocking PR #3208.
With this PR we apply `lightMask` to a `Transform` node we create specifically for a light. This mask will allow us to stop traversing such nodes sooner and avoid costly processing associated with `Transform` nodes in the cull visitor.
I have been informed by @akortunov that my addition of `Groundcover::getViewDistance` is not working in some cases. Investigations revealed that some `ViewData` code interacting with my additions had been quite thoroughly optimised in a way that was not sufficiently documented and interfered with the new feature. With this PR we repair `getViewDistance` while preserving such optimisations and add a necessary comment to avoid issues in the future. In addition, we now rebuild views when the global `mViewDistance` changes.
With this PR we refactor `SceneUtil::KeyframeController` not to require `virtual osg::Callback` inheritance. I suppose such `virtual` overhead is not justified here because it negatively impacts many other classes we derive from `osg::Callback`.
With this PR we refactor a `premultiplied alpha` user string set by `characterpreview.cpp` into a more flexible mechanism allowing us to assign any state to GUI textures. We can consider these changes more future proof than the previous approach.
