| What is the best (and easier) way to create a planet with atmosphere and others? |
| ||
| Perhaps you'd like to pin down a couple of the key issues instead of asking such an open-ended question? |
| ||
| I want to create a planet in 3d (a textured sphere) with an atmosphere (another ball with entityalpha and a cloud texture) and a stroposphere (another ball with an high entity alpha). The problem is: It doesn't look like real. Have you got any ideas? |
| ||
| What is the best way to write a science fiction novel with spaceships and things? How about the best way to build a house with a fireplace and stuff? Or the best way to make a sandwich with lettuce and fixin's? |
| ||
| Can you better describe "it doesn't look real?" Maybe with some screenshots? |
| ||
| Stupid question: what is the tag to show a screenshot? |
| ||
| What are the forum codes? |

This is a screenshot... Enormus.... |
| ||
| I'd suggest you start with something more basic, learn the various types of software you need (or would be helpful) to use. Try a dungeon, or perhaps just a large valley surrounded by mountains, they act then as a natural break. Browns the forums and code available, also the software packages. There isnt easy, and I suspect best depends on the individual. for gfx: I use Cartography Shop v4 (5 now available) Maplet Milkshape Ultimate Unwrap Painshop Pro Sound Goldwave I use other stuff as I come accross it and try it out. Taken me a while to get where I am and its still a longway from a viable 3d game, but its fun (usually lol). |

| You could try having like 5 spheres for the atmosphere instead of 2. This might help them fade together a bit more. Also, try to make your textures a bit more similar, it looks like one is grey and one is blue. I think the main thing that makes it look bad is the fact that you can distinctly see the edges of the 2 spheres. In real life, they fade together. |
| ||
| There was a thread not so long ago that outlined a very attractive solution to something that looks a lot like your screenshot. I think the atmosphere was done with an inverted spherical reflection map? |
| ||
| If it was me, i wouldn't use spheres at all, but instead a quad aligned to the planet with a blurred ring texture. That way it would fade into black in a much more realistic manner... |
| ||
| What about making the spherical textures for the atmosphere more detailed? Add a bunch of clouds and such. |
| ||
| Here's a pretty good photoshop tutorial, I spotted on 3dtotal.com a while ago. Not sure if it's any use to you? |
| ||
| Artemis, please use real JPGs, not BMPs renamed to JPG. 2.3 megabyte for a screenshot - no way. |
| ||
| Beg Mustang for a demo of his planetary atmosphere thigy-whatsit: http://www.blitzbasic.com/Community/posts.php?topic=54901 |
| ||
| k. Thnx. By the way if I'll use a more detailed texture it wouldn't look like to a real atmosphere... I've tried it. Also if I'll use more than two or three balls the program would go slowly (I want to create about ten planets). |
| ||
| Does the planet NEED to be an actual spherical object? Can it be made smaller and moved CLOSER to camera? If it's just needed as part of the background, making one face of a Skybox contain a 2-D planet image with sprites over the front giving the illusion of clouds will be much faster. |
| ||
| Does the planet NEED to be an actual spherical object? Yes, it does. |
| ||
| HI artemis i thing that the best solution is given to you by Jams. I thing that your solution is'nt realistic because you however can see the spherical delimitation of the sphere that you use. instead if you use a plane ( in a similar way of sprite in front of camera...) with an image more deformed (according with the type of atmosfere you imagine) it look more realistic. Try with this solution and thing that in this case a plane use only two triangle and so it is more fast.good work. |
| ||
| Ok problem solved!!! If anyone is interested I used a sprite to create the atmosphere (with a gradient glow ring) that faced always to the camera, three other sphere with entityalpha, the first was textured by clouds the second by the same texture but inverted and the third wasn't textured... Probably I'll create a screenshot and upload it on... so you could say how much you don't like it :D |
| ||
| That would be sweet Artemis. I'm curious;) Gnu |
| ||
| Some images :) What do you think? You can post everything ... ;) @jfk EO-11110: Sorry... :D Sun:  Planet:  The sun watched from the planet's atmosphere:  |
| ||
| I think you've over-done the effect, somewhat. |
| ||
| Maybe, but in the future (a day if I'm lucky) the planet will be far away from the sun.... so I won't see the "big star" if I reduce the intensity of the "light"... By the way do you like it? |
| ||
| Yeah, it's looking good. :) |
| ||
| Thnx :) |
