I'm working on a 3D model f the Earth and Mon, with a few other objects. I run into what seems a difficult issue ... the size of the moon.
I my scene I have placed a scale Earth and scale moon placed a scale distant apart. The moon is WAY to small.
In my scale one unit is equal to 500km; my Earth's radius is 13 units (a tad large), the moon at 3.5 units is placed 700 units from Earth. When I
place a camera in "Eath orbit" (about 360km altitude) and pint it at the moon, it is so small that it is hardly visible. I checked and rechecked my
scale, and all seems correct. I've even lace a model of ISS in the scene as a sort of reference since I can find photographs of ISS and the Moon. With
ISS properly scaled, and the camera positioned about 20km away from ISS, the Moon is virtually lost behind the station.
Now its not like I can't fix it, I can always increase the size of the mon, ad sice the animation I want to build doesn't require I go near the Moon,
it shouldn't be hard to make it "look" good, but, I will know that my Moon is way to large (I have to make the moon larger than Earth for the
"illusion" to work).
So I'm wondering if anyone can tell me what might be happening here, what am I doing wrong? I ean, I always thought that scale and perspective work,
but as I can now see .. not always.
