I want to use navigate mesh  to find route, but I don't have idea how to.
how to create navigate mesh,  how to navigate through the mesh, the basic theory is clear, but implement is another thing.
Do anybody help me, I want source code and demo app
Thanks a lot

I want to rotate my air plane when it's turning, so I call Object3D.rotateZ for help, it works alright.
but, when my plane climbing up, I call rotateX first, then call RotateZ, it does not work the way I want it to, RotateZ seems to rotate the plane around it's old Z axis (before rotateX was call), and I want to rotate the plane around it's new Z axis. (the plane Z asix changes after I call rotateX)
thanks

yes, I rotate camera 180.
maya's coordinate system is diffent from jpct

I do it in render thread, and I calculate the distance to its face.

Object3D.calcMinDistance() only returns COLLISION_NONE occasionally, it return the right value most the time, and my car go straight on the road, I want to calculate the right Y coordinate and rotateX to place my car on the road.

Does the model affect the calculate?  Is there any restrictions on the model? 

I increased this value to 100 * 30, but that won't help.
