Nature has won this round. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: This is all CSG, in standard POV-Ray 3.01. Working on the "50 Years After" scene got me depressed, so I decided to do another scene, still on the theme of "Nature Always Wins", but not quite as final. The grass is a height field, from a targa created with the bumps pattern scaled very small. The height fields were tiled several times, and scaled at varying heights. I wrote a C program to make the trees, as this allowed use of a recursive algorithm to create the branches, The algorithm is essentially the same as would be used to traverse a tree data structure. This program writes a very large (800 kb) POV .INC file in less than a second. Since this is a "flat" file, consisting only of cones and discs, with no symbols created, POV parse time is very fast. The tree trunks were done with SPATCH. The trees are patterned after my very old apple trees, which tend to spread wide, with very tangled branch growth. However, the leaves are more like maple or oak leaves. The C program is parameterized to make various tree shapes, but this feature is not complete, so I stuck with the apple trees. The scene contains 7442 objects. The deer are a combination of blobs and SPATCH, although it probably would have been easier to use blobs exclusively. The tractor, lawn mower, birds, and bees are all CSG. The lawn mower is a model of the one I use, a big engine and small blade, able to cut thru anything except bees' nests. The antique tractor is a McCormick-Deering 10-20, of about 1920, which closely resembles the contemporary Fordson, but was a much better tractor. Note that the color of the grass is different in the two scenes. This shows the difference between wild grasses and domestic grass of the "bluegrass" family.
