I'm making my own .obj files in Sketchup and then opening them in Jitter with jit.gl.model.

Let's say I start with a simple, wireframe cube -

I want to get the x,y,z co-ordinates of the cube's 8 vertices and have them updated as the cube moves in 3D space.

I then want to map the co-ordinates of the moving vertices to a panning algorithm.

Does anyone know how to get these co-ordinates and have them updated in real time?

you can output a matrix containing transformed vertex positions of a model using jit.gl.model @matrixoutput 2

note that enabling matrixoutput mode will prevent the model from drawing in the context, so either duplicate by using another jit.gl.model object, or use the matrix-output vertices with something like gl.mesh.

Could you tell me how I format the matrix output? What the list is made up of?

I've tried attaching a message box to see what the list looks like but the patch crashes every time I do that.

For now I have attached a pwindow (see patch) which I think shows the x,y,z co-ordinates expressed as colour values. This looks nice but, I need to identify a vertex and track its x,y,z co-ordinates in numbers.

just depends what you want to do with the values.

jit.iter or jit.spill are probably what you want to look at.
