I really like the feature list of jpct, especially because it's not a wrapper around an existing c++-engine (with all of its problems). The project I want to work on needs terrain support. I saw that terrain is managed in the example just by loading a .3ds file. Is there support for terrain based on heightmaps, perhaps even with automatic LOD or culling? Most other 3D engines have this, and jpct seems to have all the great features except this one. Or did I miss something?

When I run the examples (and I guess this happens with every jpct app) I get a VM crash. The log is pasted below.
My system uses the newest JDK (1.6.0u2) together with Vista 64bit.
