Summary[edit]

Description
English: Sphere wireframe - perspective projection of a sphere. The image shows lines, which are drawn as they were painted onto the surface of a sphere.

viewer distance from center: 4r
line distance: 15°
line width: 1°
axial tilt: 37.5°
rotation: 11.25°
base color: #22326b

all shapes are drawn with cubic bezier curves to an accuracy of 0.00001 of the radius.

    Sphere wireframe
    depicted with perspective projection

    viewer distance from center: 4r
    line distancd: 15°
    line width: 2°
    axial tilt: 37.5°
    rotation: 11.25°
    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.
