It takes on values from 0 to 1, which represent percents of solid opacity. It's initial value is 1. 2. `color` — It can be specified as `Int`, `String`, or as three `Ubytes`, which represent color in `rgb`. Elementally, the solid will have `green` color. + 3. `rotation` — it's the point, which sets rotations along axes. Initially, the value is `Point3D(0, 0, 0)`. Changing `x` coordinate of the point, you make pivot around `x axis`. The same for other coordinates: changing `y` — pivot around `y axis`, changing `z` — pivot around `z axis`. + 4. position, which is given by values `x`, `y`, `z`. Initial values are `x = 0`, `y = 0`, `z = 0`. The coordinate system is Cartesian. It's elemental position is this — vertical `y` axis and horizontal `Oxz` plane. Let's see how properties are set in solids.
