pretty nbody simulation

[jimbo007]

Hi all,
I have been working on doing an nbody simulation in vpython.  It does almost everything I want it to including multi core processing, rotating and zooming however I would like to make it prettier.  Just wondering if vpython is capable of producing something exactly like the images below (fog/smoke/glowing effects).  If it is capable how would I go about creating it?
<blockquote class="imgur-embed-pub" lang="en" data-id="ly63Z"><a href="//imgur.com/ly63Z">nbody</a></blockquote><script async src="//s.imgur.com/min/embed.js" charset="utf-8"></script>

If not could someone point me to the tools required to go about creating this?

Thanks in advance!

Looks like I dont know how to embed images, here is a link instead for attempt #2

One option that I did for have a background, it was to create a big sphere as Bruce suggested once, and use the library "Image", so with this it's possible to load your texture on the image, and it looks very nice.

This is an example of code:

tex = materials.texture(data=materials.loadTGA('wallpaper.tga'), mapping='spherical')
	sphere(radius=200, material=tex,axis=(0,0,1)) 

The only detail, is that you have to convert the image to "tga" format. I hope this help.

Greetings!

None of the various VPythons currently supports fog or smoke, but as for glowing effects the GlowScript and Jupyter versions do have this object attribute:

emissive If True, local and distant lights are ignored, and the brightness is governed by the object's own color. An example of its use is to put an emissive sphere at the location of a local_light, which looks like a glowing lamp. The default for emissive is False.

Thanks Eric and Bruce

hi Eric,
recently I've been trying a new project and I wanted to try reading tga files as textures like your example,
def material(name): 
 name = join(join(getcwd(), "textures"), name) # textures folder
 material = textures(data=textures.loadTGA(name), mapping="spherical")
 return material

However, I am having difficulty processing textures with the pattern above because 'materials' can no longer be used in Python 7. Would you like to help me? sorry I'm still a beginner

Here is the page of the VPython documentation dealing with textures:

Here are a number of examples of programs that use textures:
