| Image title | Sphere wireframedepicted with perspective projection viewer distance from center: 10r line distancd: 10° line width: 2° axial tilt: 37.5° rotation: 7.5° base color: #22326b plotted with several adapted cubic bezier-curves The plotcurves were calculated by some fancy python code. The bezier-curve controlpoints are placed on tangents of the function-curve. They are furthermore positioned in a way to minimize the average quadratic distance between the bezier-curve and the function. This gives an accuracy, so that the deviation is in no point greater than 0.00001. about:http://commons.wikimedia.org/wiki/Image:Sphere_wireframe_10deg_10r.svg source:http://commons.wikimedia.org/ rights: GNU Free Documentation license,Creative Commons Attribution ShareAlike license |
