• improved performance of the midpoint path search by 80% using SSE2 optimization and other optimizations. (SSE x86 only, other platforms around 30% improvements)

xaitMap Library 2.8.0.2000

xaitMap 2.8.0 supports a couple of new features. Here we summarize the most important ones:

• Unit Radius Support": The new version of the NavMesh now includes info about the radius of the unit which is supposed to use the navigation mesh for navigation, in addition to the multi-character approach which stores various heights of characters etc.
• "Enhanced Treatment of Height Fields": xaitMap 2.8 comes with a completely new NavMesh generation algorithm that delivers a NavMesh of even better quality; especially the NavMesh representation of height fields is way more efficient compared to previous versions.
• "More efficient navmesh generation - better memory footprint and fantastic build times": The new highly efficient NavMesh generation algorithm tremendously reduces memory size of the NavMesh, therefore the average node count and – in turn – speeds up pathfinding, as well. 
• "New pathsmoothing algorithms": In addition to three fast and reliable pathsearch functions, xaitMap 2.8 comes with a new funneling based pathsmoothing as well with a new raytracer based pathsmoothing mechanism which give you great results.
