Trace: 1hr 12 min. 47 sec. HARDWARE USED: Anthon 1.2Ghz 256 Meg RAM IMAGE DESCRIPTION: Time to feed and water the cows in my nabor's pasture on a winter's late afternoon. The sky is clear and the sun is going down. Looks like it'll be a cold night. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: This is my Twelve entry. This round's subject had a lot of possibilities. I had just made a snowflake pov that used random points in a prizm, then rotated copies of that prizm around a center. It made a pretty good snowflake. My first thought was to make a few hundred of them and place thousands of copies of them in falling onto a field. But My last entry was abstract and I wanted to do something different. Maybe a airplane with elves making and throwing out snowflakes.(still to abstract) So I looked around where I live. I live in the woods. Really, I have an acer of land surrounded by trees and hills. I have play with making trees but I never truly liked the way they came out. I didn't think I would be able to do justice to my woods. But there is a valley not far away that would do. SCENE : size: 800 * 600 antialias threshold .1 method 2 depth 3 frame level objects: 21,938 lights: 1 white 1 light_group white Sky: a simple shy_sphere with a gradient y pigment tilted slightly Objects: pasture: a height_field with 'blob' placed in the foreground using trace This is the first thing I did, I play around with height_fields and lights and textures until I found a good combination. Even so the height_field in the foreground look to stark so I added 'blob' there to smooth things out. Hills: a height_field covered with mesh trees using trace. I tried to use USGA data to make the height field but the data I have was to course. So I had to make my own. For the trees I first tried to use textured spheres to have the appearance of trees. They looked like gaint snowballs. So i decided to try Gilles Tran's Tree macro. A few sample trees told me that wouldn't do.(to slow to much memory)I even try a macro I wrote for an earlier round entry, ReversTree. Same thing. I decide what I need was a mesh. More about this under Trees. Trees: When I decided to use mesh1 for the trees I download Paul Danson's "ptdtree3.zip" And took a look. It was not what I wanted. But it gave me an idea. I could take my ReverseTrees macro change it to generate a mesh file. (it is in the zip file as MeshTree2.pov) Then I made 12 different trees files. When I place a tree on a hill there are 2 identical meshes one textured with snow and the other Brown. The snow one was moved up and to the left just alittle and both rotated randomly. I like the effect so much that I use the same technique for the trees along the fence. Fences: 2 side fences: simple cylinders,spheres and cones texture accordingly. I had to shorten each post away from the viewer, because the scale of the height field, to keep perspective. Not hard, all I had to is add a little equation in the While loop that place them. foreground: The post here are the same as for the side fences rotate a little from vertical. The wire was the fun part here, first I use 'sphere_sweep' which made pretty good wire. But trying to place the barbs with 'spline' function didn't work. So I use 'spline' to make the wire and place the barbs. I left the lowest wire a 'sphere_sweep' so it'll look more covered with snow. Weeds: Grass: from 'Gilles Tran's Grass macro' I played around with this until I got the grasses I wanted. When I place them with only the main light they where Black. So I put then in a light group with global set on. They fit in pretty well with the 'blob'. saplings: more of my meshed trees scale way small Cows: are CSG I made a macro to move the legs,head,and tail Truck: is a combination CSG with prisms,sphere, cones. With 'blob' snow thrown on using 'trace'. I worked a lot on the detail here. There is a man sitting inside that's hard to see because of the mirror. I like the way the snow half berried the headlights. radio towers: cylinders pigmented using 'gradient y' and 'no shadow' Hay and holder: The holder is made of cylinders and torii The hay is cylinder pigmented with 'gradient x' .25 turbulence and 'normal{agate}' Water trough: The container was inspired by a bucket in POV 3.5 include file You can barely see the water. I can't decide if it's ice or not. House: boxes textured and tilted appropriately there is even a fence around it using only a textured box epilogue: There are a few things I'd like to clarify about this scene. First the area on the hill where there are no trees, is where a power line is going in. At first I didn't like it and wanted to have this scene as my protest. I used to fish in the creek that runs along that ridge (twenty years ago). But now that I have though about it, I have no right to complain. I'll probably use that electric to make even more pictures. Second the creek in my scene is not seen, but is represented by the lack of trees. I thought about adding fog there but the creek is small and the trees are tall. It couldn't be seen any way. And lastly I wanted to say something about the sky. Its plain, I know, but I've seen winter days like this and I know that when night comes it will get bitter cold. I hope that this sky in this scene gives that feeling of that impending weather. Zip-File: Grnwood.zip should have everything to parse the scene. There are 24 files in it.This is the first time I am trying to put such a big project into a zip so if there are any omittions let me know.
