I figured I would spend a few days working with the Recast Navigation library and wrap the functionality up in some simple classes. I've implemented half a dozen third party libraries in the past with no problems, but I'm finding Recast to be much more difficult than I anticipated. There's no documentation, and the example provided has the pathfinding code mixed up with rendering, .obj file loading, and a GUI, so I can't tell what anything is doing.
Are there any tutorials or documentation, or just an explanation of what commands to call for this library, anywhere? I don't have any specific questions, I just can't tell how to even get started. Any information you can provide would help, thanks.
Sorry for the late reply, I had this problem also, found no tutorials or anything. My best tip is to read through the example code, I found it not so difficult once I got started. Look through Sample_StatMeshSimple.cpp especially the function bool Sample_StatMeshSimple::handleBuild(), it is quite well commentated.
I build my nav mesh from a waveobj memory buffer instead of an actual file. I generate this buffer from my geometry. I then load the buffer using the existing methods rcMeshLoaderObj::addVertex rcMeshLoaderObj::addTriangle. The resulting mesh needs to have it's bounds calculated before the nav mesh can be built from it:
