Title: Habitable Zone ??
Post by: karakris on July 20, 2011, 12:45:50 PM

The Habitable Zone used to be shown by a green band around around a Star.

Now it is shown in my views as two elliptical lines, at right angles to each other.

This is almost useless for determining if your Panet is in the Habitable zone or not.

No, it's not. Now, you can see if it is in the habitable zone by checking if it's between them. Also, it allows you to see if orbiting planets that are very ecliptic are within it. I think it's a great addition, myself.

The habitable zone was represented by a torus, which was incorrect as the habitable zone is spherical in shape with an inner and outer edge.

The change isn't as aesthetic, but is more accurate.

Look for an aesthetic improvement in a distant, future build.

But why did you change it to rings instead of solid green? Because that's easier to determine in my point of view.

Representing the Habitable Zone by a sphere in any manner is a nonsense

Seeing as you can only put Planets in one ecliptic ( orbital ) plane - any other axes are meaningless.

Nice for info - if you can make sense of it
But irrevelant for actual placement of planets.

But, there is no ecliptic plane. It should be one of the options you can select with a star.

Wait, what? It is possible for planets to have high orbital inclinations, you know that, right?

You Can ????? !!

I was told by Dan that there is NO option to change the Orbital Plane -
for Planets, for Binary Stars or for anything

Has this now changed ??

You can't change the "zero" point, but you can change the orbital inclination. Without a spherical display, highly inclined orbits may appear to go outside the HZ when they actually don't.

Place the planet on the locked plane, then select the planet and change the inc (inclination) setting in the Orbital Elements section.

It's a bit clunky right now. I expect to improve this in a future build.
