Coordinate systems
All plot specifications requires a coordinate system. By default, rectangular (Cartesian)
coordinates are used. This can be changed to polar coordinates by using .gg.coords.polar (see .qp.s.coord).
.gg.coords.cube
3D coordinate system
3D points are plotted via orthographic projection onto a 2D plane, which is tangential to a point on the unit sphere defined by 2 angles, the azimuth, and the altitude.
The azimuth is the angle between the point and the X axis along the X-Y plane. The altitude is the angle between the point and the X-Y plane. For more about azimuth/altitude, see: https://en.wikipedia.org/wiki/Azimuth
Parameters:
| Name | Type | Description |
|---|---|---|
| azimuth | float | |
| altitude | float |
