OpenGL future for vector maps and everything else
The future of mapsforge is OpenGL rendering: https://groups.google.com/forum/?fromgroups#!topic/mapsforge-dev/U_NqCpSuUhA
There is already a nice proof-of-concept app (Cruiser) that takes a mapsforge offline .map file and renders it via OpenGL... in a speed that is easily ten times that of Locus, probably with half the battery usage, free 3d and free rotation included: https://play.google.com/store/apps/details?id=gr.talent.cruiser&hl=en
I know the Locus teams hates and ignores 3d hardware... but can't you just hire this guy? Its so wrong that our phones can render quadrillions of texels per second and yet Locus will keep struggling with 2d maps and a few tracks and points forever.
