   Looking for a terrain renderer for a conversion
  I'm looking at doing a partial-conversion of an old flight-sim - the aim being to replace the old rendering code by something better.To do this I'm looking to hook into an existing engine or find a suitable code library which will render a huge terrain ( ie.  a minimum of 16k x 16k height points represented as tiles of 2k x 2k ).The plan is to add calls into this new terrain renderer from the old code and gradually deprecate the old renderer.As this is a professional project,  the client is prepared to pay for a 'pro' version of which ever software does the job.In an ideal world it woud be nice to just buy a 'terrain renderer' which can be called with data from the application.....I was hoping someone might be able to recommend a suitable renderer or engine which could be used for this.Cheers   
  I think one post should be enough to deal with this problem!   ;  I don't know of anything off hand that would do that. That is the kind of thing you typically have to write on your own.My own online RPG engine would do the job. One sub map is 64x64 sections with each section 1024x1024 with a nicely optimized multi texturing terrain system.;Horde3D can load 2k heightmaps and do automatic LODing on them. You should also be able to make an 8x8 grid of these 2k heightmaps to get your 16k data in there like you want.This is a full OpenGL renderer though, not just a terrain plug-in for an existing renderer.   ;  Ogre3D has a PagedGeometry addon that might be what you are looking for.
