| Members | Description |
|---|---|
| kAcGiWorldPosition | Specification of transforms in world space. This is the default behavior |
| kAcGiViewportPosition | This is a normalized viewport 2D coordinate system, X and Y axes running from 0.0 to 1.0, with (0.0, 0.0) at the lower left and (1.0, 1.0) at the upper right |
| kAcGiScreenPosition | This positions the geometry in absolute pixels |
| kAcGiScreenLocalOriginPosition | This positions the geometry in absolute pixels by specifying a 2D position for the 3D local coordinate system |
| kAcGiWorldWithScreenOffsetPosition | This is specification of position in world space with a screen space pixel offset - useful for something like a label which should track a world point |
