Use of Grids
Geometric Modeling
Coordinates
In practice, Cartesian coordinates are default in most CAD packages.
Also the right-handed orientation is used.
Rectangular: (x, y) Polar: (r, θ) |
Rectangular: (x, y, z) Cylindrical: (r_{c}, θ, z) Spherical: (r_{s}, θ, φ) |
Right handed systems are the dominant convention.
