JPGFILE: br_globe.jpg ZIPFILE: br_globe.zip RENDERER USED: PovRay 3.5 Beta (but only the fonctionnality of the 3.1g) TOOLS USED: L_syst (an home made tree generator) RENDER TIME: 8 56 50 HARDWARE USED: Laptop with Celeron 650, 128MB of RAM, 10GB of hdd IMAGE DESCRIPTION: When I saw the topic of this session, I immediatly thought to those little spheres that we buy during the vacation which show you your vacation location under the snow when you turn it over. Here, the object has just been keft on a table, and as it is magic, it is still snowing... DESCRIPTION OF HOW THIS IMAGE WAS CREATED: This image was created directly in PovRay, with the Windows version (and then its GUI). The hardiest for me was that, as I didn't find any acceptable open-Source program to render a tree (sure I'm not very aware of searching techniques with google), I simply decided to... programm it. The result can be found at http://revelut2.rez-gif.supelec.fr/peros/L_syst/index.html (site all in French, I 'll translate it one day). The result is quite hard to use, but I know then perfectly how it works, and I personnaly have no problem to use it, which was in fact my main goal. Well, this ever took me quite a lot of time. The second problem was how to make the ground. I wanted to use an height-field, but it is also really hard to find a good editing software, and as I had no time to programm it, I chose something else. I finally decided to us blobs to make the snow. The little house was not really a problem, it is made easily with a macro and some loops. The table and the wall behind are also quite easy to make, beacause they use easy fetaures and textures. Last but not least, the falling snow : that was my harder problem, in terms of time and of work ad of... After having tried media (it took me 2 days to realize I was really unable to use those primitives - Well, I regret halo of pov3.0 ...), I tried using spheres. After some work this was looking quite gteat. So all flakes of snow are in fact little no_shadowing spheres. they are placed randmly in the sphere.... and that's all! In the Zip file, I included everything to render the file. I also added L_syst.exe, my djgpp windows compilation of the soft I spoke about 2 lines above.
