points dividing the whole shape into ranges where the functions apply; points
coordinates should vary within (0.0, 1.0) range. Parameter *t* of the spacing
function f(t) varies from 0.0 to 1.0 within a shape range.
+ Note:
+ The actual grid spacing can slightly differ from the defined one. This is done for the
+ best fitting of polyhedrons and for a better mesh quality on the interval boundaries.
+ For example, if a constant **Spacing** is defined along an axis, the actual grid will
+ fill the shape's dimension L along this axis with round number of equal cells:
+ Spacing_actual = L / round( L / Spacing_defined ).
Examples:
"10.5" - defines a grid with a constant spacing
