Question: 1 Tile = 1 km ?

[Phoenix711]

I remember two different things from what I searched/read at all... (For 512 tiles only)

1. 1 Tile = 1 Kilometer Square. Means one tile is 1000 m x 1000 m

2. 1 Pixel = 1 Meters

At the second option, 1 tile makes 512 m x 512 m, thus making a smaller area.

Which is true?

Now I use, 1.37 km Eye Alt from Google Earth, and results are satisfactory in size realism/speed feeling. (IMO). 660 pixels make 1000 meters from that altitude of sight. It is like in between the two options.

What is the correct value for Falcon?

Thanks.

The terrain mesh for Falcon is 1km by 1km. Any tile applied to that terrain mesh will be adjusted to that 1km by 1km size. So depending on the resolution of the tile the pixels on the tile amount to different "sizes" accordingly.

Only to add that the mesh in Falcon is not exactly fixed, because Islandic Theater is L2 mesh ~250m and L0 mesh ~75 m resolution.

Rest of the theaters, AFAIK L2 mesh ~1000 m and L0 ~250 m. Each tile maps to a L2 polygon, so then, if 256 px, then 1 px ~4 m ; if 512 px, then 1 px ~2 m ; and if 1024 px then 1 px ~1 m.

If you use 660 px then... is it working? I am shocked!

I suppose you resize to 512.

Good addition Closter.

Guys

Sorry, I don't understand the resolution issue completely. Basically, 512 tiles are better, right?

If I take a screenshot of Google Earth at 1.01km and make 512 tiles will they be better quality than if I make them 256 from the same screenshot?

Or, should I decrease my distance by 1/2, IE 0.5km for 512 tiles, so that there is twice the detail?

The air weapons range that I am using GE tiles for doesn't look good closer than 1km. Does this mean that I could have better looking tiles by taking a screen shot from a farther distance and making smaller tiles? That seems to go against the impression I have gotten.

Thanks,

Epic

No. Anything other then 128, 256 or 512 crashes. My tiles are 512. I just said, I work from 1.37 km eye alt GE, draw a path of 1 km, it makes 660 pixels. At about 1.80 km eyealt, 512 pix. makes 1 km

For realism and true feel of speed (like one can say "I am flying like 450 knots" and hes really flying close to that) the correct eye alt should be used IMO.

For example, if you use 6 km eye alt, that would create so funny results. One 1 km tile of falcon would include so many things that, at 5000 feet, you will feel like you are flying at like 20.000 feet and very very fast.

That's the base of my question.

Thanks for the interest and information.
