2. Coordinate SystemsΒΆ
Coordinate system is a system for assigning an n-tuple of numbers or scalars to each point in an n-dimensional space. It anchors the regions within the real world. Coordinate system can have different types such as:
- Rectangular cartesian
- Cylindrical polar
- Spherical polar
- Prolate spheroidal
- Oblate spheroidal
There is a global (world) coordinate system aligned with 3D rectangular cartesian space.
Coordinate system has the following attributes:
- User number
- Finished tag
- Type
- Number of dimensions
- Focus (for prolate-spheriodal system only)
- Origins
- Orientation
