| The first comment that springs to mind is there are no screenshots. Yes it sounds picky, and aye, its not helpful if you are looking for comments on the content. It is important though. Unless the reader is already familiar with techniques in cloud rendering, they probably aren't going to invest nultiple hours getting giving the artcile a go unless they know they are going to end up with something worth while. -Phil |

| Screenshots don't illustrate it nearly as well as running the demo and seeing it in realtime. |

| Having seen some nice real-time cloud rendering stuff in action, I would agree with you Rhino that actually seeing it in motion is the best way to appreciate it and to understand what's going on. However, I think the first commenter does have a point. A literary critic (as opposed to a technical one) would probably make the case that screenshots are a nice tool by which you can draw in readers who may otherwise think that they aren't interested. |

Quote: Yep, thats the message I was getting across. Also, I didn't even know there was a demo to try out. In order to find that information out, I had to download the source code, which I wouldn't do unless it was superior to the cloud techniques I've seen. See what I'm getting at? The more useful immediate information there is, the better it is for the reader. A reader's time is valuable, and the easier you can make it for them, the better. - Phil |

| Definately go ahead and download the source. There's an exe in there and the demo is pretty cool. It pops a bit, but it's quite nice. |

| Strange artifacts with a geoforce4 , looks like the impostors have a white band when rendered |

| This is a nice summary of Harris' paper in terms a graphics programmer could better understand. I would strongly suggest to anyone interested in this to check out his website. Slaru |

| Just curious, but is this process really practical for games? Seems a little too intersive to me, especially if your game isn't completly based on clouds. It looks really great though! Have you ever tried adding so physics behaviour to the clouds? It's probably not to realistic but it'd be neat to be see like a ball or something fly through and scatter the clouds. Anyway, cool stuff! Matt __________________________________ [ Website ] [ Résumé ] [ Contact ] [ Have I been Helpful? Hook me up! ] |

| Harris' latest paper "Simulation of Cloud Dynamics on Graphics Hardware" appears to add physical animation to clouds ("entirely" on the GPU). I read the paper a little while ago, but I haven't tried to implement the technique. As an extention to this article, I'd suggest checking it out if you feel like deciphering an academic paper.

| The cottonball cloud approach seems to only look reasonable if you aren't actually getting very close to them, which defeats their purpose in being quasi-three dimensional. There are plenty of 2D techniques that look better from a distance IMHO. [edit] Though I hope I didn't offend anyone and their research efforts. [/edit] |

| Hi, I've problem to compile source code from this article. It say many 'external symbol unresolved' in .obj file. Looks like linker problem. I've downloaded DevIL 1.7.8 and SDL-1.2.13. Looks like I've include those library,, (dll, .h, .lib etc). I'm using MS Visual Studio 2008 and also include glut stuff Did I have something missing out there? Or maybe I'm missing project settings or something.. I'm glad if anyone answer my question here... Regards |
