I've got a little question. I perfected the integration with QCAR's engine, but I am faced with a doubt.
If I create a 30 units big cube and don't move it at all, it looks like the cube lies "beneath" the marker, so if I rotate the camera around it you can see it rotate as though it was inside the marker instead of above it. Obviously this is difficult to see (and probably to understand without seein it), but to clear things a bit it is as though the marker is positioned at (0, 0, 0) facing Z positive direction, and the cube lies at (0, 0, 0) but extends towards Z negative direction (or maybe it is the other way around).
For the cube I can just move it 30 points towards the positive z direction and I'm done, but with models I wouldn't know how much to move them so they lie perfectly above the marker. How can I solve this?
Does this all make sense to you? I'm not very clear as to how JPCT positions objects, or what is the difference between center, origin and transformed center...
