GMO Coordinates Basics

The basic test that demonstrates relationship between three major coordinate systems in GRIFIN. A round-trip for coordinates conversions starting from GG to GCS to LCS, and back to GG:

1. XYZ Local Coordinates (LCS): suitable for rendering on graphics hardware (using 32-bit float numbers)
2. XYZ Geocentric (GCS): the unifying coordinate system fundamental for indexing and accessing objects in GRIFIN
3. Geographic Coordinates (GGS): used in geographic applications for referencing features close to the Earth’s surface.

This test is useful for debugging of GShape/GElement representation in GMOs.
