A question for Planetside Staff... Where do the base co-ordinates, i.e. x=0 y=0 z=0 get calculated
from?
It
isn't the surface of the default planet because, when I shrink this planet, the x,y,z co-ord's are no longer on the face of the planet. Shrinking the planet radius, to me anyway, should mean that the x=0 y=0 z=0 position should be offset to the surface of the resized planet because the central point isn't being moved. Not so! They are left in mid-air, whilst the shrunken planet now reports negative 'y' co-ords on its surface.
Are the default x,y,z planes somehow linked to planes calculated directly in the centre of the background node or something? I mean, where does the default planet calculate these co-ords from? It can't just be empty space.
As I type this it sounds more and more silly, I know what I mean but not how to explain it.
The planet/scene is obviously built around a point in empty space, designated 0,0,0. With no items at all in the scene, this point will always exist, I get that, I don't get, however, how the default planet's central-core point is calculated and how this is translated to match the surface of x=0y=0z=0.
In a nutshell: Can I make a new planet/atmo, zoom to the surface of that one to render from, look back to my default planet(where the co-ords are calculated at 0,0,0), then disable
it's surface rendering and then, move
entirely everything that's linked to the original default planet via its bounding box?
Phew! I'm whacked! I dunno, I'm probably talking out of my arse!
