Alan's Cloud Generator (beta)

  Published by Kernon on March 13th, 2008 in 3D News, Python Scripts

Alan (aka RipSting) writes:

I've been doing a lot of atmospheric modeling lately and wrote a script that generates some cool interactive volumetric clouds! Not only can you see the shape of your clouds in the interactive 3D window, but you can animate their properties with IPO curves.

When you're done automatically generating points, you can edit them and delete the clouds that you don't want. Then, it turns the clouds you DO want into faked volumetrics. I say fake, because it will only render correctly from the camera's perspective, so it won't work that well yet with extreme reflections.

Here are some sample renders and animations:

You can download the latest version of this exciting script and keep up with the latest development news and discussion at the blenderartists discussion thread.

    Really cool :)

    Looks cool, but why is it so dark where it blends with the background?

    Hi All,
    I'm excited to see this here on BlenderNation! I will be uploading a release candidate within the next week with many improvements in ease of use, previewing, and cloud shaping.

    Raffy: The picture isn't loading for me, but if you're referring to the cloud fly-through animation, it's a result of compositing with nodes. The clouds were rendered separately from the water, and the alpha channel didn't quite render as I had hoped.

    I just tried some inhouse-visualisation with influence of environment-maps. Is this a plugin? Where can I download it? is it in svn? looks really great… thanx.

    Wow 100% greatly

    wow wow wow!

    Alan,

    You might need to render the clouds premul or key instead of sky to get the compositing to work without the black edges. I just went through this and brecht set me straight.

    then it can be composited similar to this: http://www.tsiwebdesign.com/testing/screen2.png

    hope that helps

    I just tried this script. The results look very promising. Thanks for your hard work.

    Exellent work RipSting !
    Another magical world now open to blender ; fantastic for all flight combat scene through the clouds.

    This really looks good. I'm tired of using the plugin cloud texture on a skydome….

    Something else I saw in the first animation.
    When Suzanne is falling through the cloud, I don't see any shadow from her in the cloud.
    Is this going to be fixed?

    niiiice. finally i can be superman :D

    Really really cool!! =)
    Thanks, Alan!

    AHHHHH! I have been waiting for this. It would still be nice if it wasn't faked but as long as it looks good and is easy to use….

  18. 18 KevinW Edit Link Mar 14th, 2008 at 12:09 am

    Blender REALLY needs proper volumetrics.

    This is a step in the right direction!

    Thanks!

    very cool stuff!
    that's what I'm wait for!

    Great work!

  23. 23 ROUBAL Edit Link Mar 14th, 2008 at 1:14 pm

    Well, it is an amazing step ! Thanks a lot !

    I was thinking about purchasing Vue 6 to get volumetric clouds, but maybe Blender will do this before I will have the money for purchasing Vue 6 !o)

  24. 24 DramaKing Edit Link Mar 14th, 2008 at 7:12 pm

    Isn't there already a cloud generator in the works for Blender?

  25. 25 Edward Edit Link Mar 15th, 2008 at 1:35 am

    This is the sort of tool that I have been waiting for since I started with Blender. Great!!!

  26. 26 terence Edit Link Mar 15th, 2008 at 6:03 am

    Great timing. I have just started working on an animation job that requires flying from space down to earth and I was wondering if I was just going to have to use a cut scene to skip the clouds. Now, maybe not. Thanks for the great script

  27. 27 Daniel Ludwig Edit Link Mar 15th, 2008 at 2:41 pm

    Congratulations, a good job.

  28. 28 Dion Moult Edit Link Mar 16th, 2008 at 9:56 am

    Definitely going to use in my upcoming animation.

  29. 29 Conrad Buck Edit Link Mar 17th, 2008 at 5:10 pm

    YOU ARE THE EFFING MAN! KEEP UP TEH GOOD WORK!
