Selden: Bumpmaps cannot be used for models in Celestia. Normalmaps have to be used instead -- and they will not be usable until v1.5.0 becomes readily available. The 3D Nebula models that are currently available are shaped entirely by the locations of the vertices in the models. However, one can cre...

Ask again in June. This is not a simple task and I do have a real job...

Fridger:

Please retrieve your e-mail from me...

The first task for me is to assemble all of the information available. This would include any photographic information. I will incorporate as much REAL data as possible. The primary algorythm, however, will build upon shadows and contrasting hues; water vs. land. Again, references to the location of...

Fridger: This is, of course, my intent. I appreciate the information and references that you have provided here. I can also appreciate the size of the task for which I have volunteered. Any help, suggestions, comments, etc. are more than welcome in my house. The proposed algorythms for terrain are c...

Chris etal: I have recently posted under 'education' that I AM currently working on an application that will 'translate' 2-D texture images into 3-D models. The end result will work for producing landscapes, gaseous nebulae, and galaxies. I hope to have it finished some time this summer. Upon comple...

Thanks. The only thing that's missing with images like this one is the landscape. I am currently working on a program that will produce a 3-D model of a texture file so that when one zooms in this close they actually see the surface features (mountains, craters, etc.). It might take me some time so ...

Okay Johaen:

How's this?

Hope this works...

Chris:

Upon completion of your new code could it also be used to create Gaseous Cloud Nebula (see NEBULA)?

Also, there are usually several cloud levels that move at diferent velocities. I attempted to place multiple levels around Jupiter with no success.

Selden, et al: Yes, this is what I meant by nebulae. An example would be the Orion Nebula. cloud of dust and gas by the light and stellar winds I will have to visit the link that you have posted here. thank you. I still pose the question about displaying these objects in CELESTIA. I learned today th...

cheers...

I'll try that. Hopefully we'll have a Vulcan Sunset for you to observe. The image is the original that I used for my ICON here. You can just see the three planets and the sun behind the enterprise. The original image doesn't have the enterprise in it.

Johaen: That's very interesting to me. My opinion is the exact opposite of yours. I guess it's totally possible; just curious. I see them linked (Science & Sci-Fi) probably because of my childhood experiences (see above). Now I wonder about your childhood. What era did you grow up in? I was a '6...

Hello, I petty new to this stuff (CELESTIA) but I am a vetran programmer. I was disappointed when I zoomed into my first nebula. This 'bumped' flat image was not very realistic to me. I realize that we really have no idea of how these nebulae are dimensioned, yet, one can imagine that these are spar...

Now, that's what I'm talking about! This is a great teaching aide and letting the kids expand their minds with alien lifeforms, wow! Will you be my teacher?

Okay, I have a question. How do I get an image uploaded to this forum; you know, like that one guy did above?

Okay Guys: I get it. I guess when I was a kid and looked to the stars I wanted to go there and see it for myself. Along with Star Trek, I was very interested in the Space Program. But, I guess, back then it was pretty exciting to watch (GEMINI & APOLLO). Both helped me get to the stars equally. ...

I'm a little unsure what you mean, Johaen. Are you saying that you are not familiar with STAR TREK; that it's a television program whose theme is space? I guess if you're not interested in astronomy then you probably never heard of it. But then why would you take an astronomy class? See, I'm confuse...

Kid's find Celestia hard to use? This is unbelieveable, really. Kid's that age are so in-tune with the latest on-line gaming, I find it hard to swallow that they failed your class because of that. I have never taught astronomy, but, perhaps it was the curriculum. Maybe it was TOO simple. Those kids ...

I just checked and it seems that it's not even posted yet. I don't know why. The following is the raw text (no images) of the document: How To Create Realistic Skyscapes Using CELESTIA?® Written by: Peter Allen Rosetto Wednesday, January 24, 2007 Table of Contents Overview The following instructions...

This is more of an FYI than a discussion. I have submitted a posting at MotherLode that shows you how to create great skyscapes using CELESTIA. I have only had this program for about one week now and I think it's the best thing since sliced bread! I wrote the skyscape posting for both it's education...
