The work continues on XRhodes. Implemented an XR::IndexKeeper class that will help bookkeeping fixed allocation environments, such as XR::Emitter<>, which has also been rebuilt along with XR::Particle<>; the performance and design improvements are strong with this one. XR::IndexKeeper is not something entirely new; the resource manager in XRhodes' early version has utilised a similar mechanism - it is now available in a more generic form.

Follow up:

We've got XR::GridWorld2D, XR::SpatialHasher2D and XR::ListProcessor<> to assist game logic development - XR::GridWorld2D aggregates an Indexer2D and a XR::Grid to define a 2D grid based world. XR::SpatialHasher2D, based on XR::GridWorld2D facilitates spatial hashing to accelerate collision / visibility checks. ListProcessor<> assists batch processing of objects (which is what XR::LayerServer<> has been rewritten based on it).

XR::Indexer2D can now Allocate<>() for you.

XRhodes' container types, XR::Queue<> and XR::Ring<> have also been improved, the iterators now comply with std::find() and quite possibly more. They also have been given copy constructors and operator=s; XR::Ring has now got a swap() method too.

XR::RenderRegion2D (renamed from XR::RenderRegion) has been cut loose from XR::Camera2D - you can now create it based on any viewer position and layer.

There's an XR::Auto::Begin for rendering assistance (glBegin()s / glEnd()s on construction / destruction respectively).

Last but not least, improvements have been made here and there, to both code and documentation. The code bit means that some things have changed - even though for the better, it might necessitate some refactoring with your pre-existing code, but quite possibly nothing more than some Find and Replace All fun.

But what does this all means? That's right, XR v0.86 coming very soon indeed.
