| Member | Type | Description |
|---|---|---|
| X | vector | the X base axis |
| Y | vector | the Y base axis |
| Z | vector | the Z base axis |
| mat | mat4x4 | matrix rotating from local to global |
| mat_t | mat4x4 | matrix for rotating from global to local |
This class implements a local system. A local system is defined by three perpendicular vectors (the base axis).
