NUMERICAL SPACE / ODDSPHERE
For example, I show the scene file of "Cutted odd sphere". I made this from the sample file of "odd_sphere" by Mr. Suzuki. I made other works in this page by similar scene files with this. This complicated shape is generated from only four value!

And additionary, I made a fun. I used [ accuracy 7.2 ]. The value is so big that spheres can't be figured. They changed to discs colored concentrically. | |
The value of accuracy is not so small that the surface is not smooth, having many fine discontinuous lines. But the fine discontinuous lines give a sort of texture in the image. You may not be able to see the lines enough in this small image. Please see the large image file. | |
function { D3DFUNC } color_map { [0.5, 0.01 color rgbt <0, 1, 0, 0.5> color rgbt <1, 1, 0, 0.5>] [1, 1.001 color rgbt <0,0,1, 0.7> color rgbt <1, 0, 0, 0.5>] } frequency .7 } From the location of [ camera ] many spheres are piled up and we can see a sight like a valley. | |
I may say this odd sphere a micro cosmos metaphorically like the isosurface patched POV-Ray. | |
