Interface: SkyVectorPlacement
Where a direction lands in normalized image coordinates (see skyProjector).
Properties
| Property | Type | Description |
|---|---|---|
<a id="behind"></a> behind | boolean | True when the direction cannot project (gnomonic-side horizon). |
<a id="hemisphere"></a> hemisphere | "near" | "far" | Near hemisphere (theta <= 90) or far. Under positive shape the far hemisphere folds into the same disc; consumers depth-sort with this. |
<a id="thetadeg"></a> thetaDeg | number | Angle from the aim, degrees. |
<a id="xn"></a> xn | number | Normalized position: +x right, +y up, magnitude 1 at hfov/2 from the aim. Signed Infinity when the direction is past a gnomonic-side horizon (behind). No aspect ratio is applied. |
<a id="yn"></a> yn | number | - |
