pub fn hex_predict_grid_position(
grid: &HashMap<GridIndex, Point2<f32>>,
idx: GridIndex,
) -> Option<Point2<f32>>Expand description
Predict a hex grid corner’s position from its neighbors along three axes.
Uses midpoint averaging on up to three opposite-direction pairs:
- E/W: midpoint of
(q-1, r)and(q+1, r) - NE/SW: midpoint of
(q+1, r-1)and(q-1, r+1) - NW/SE: midpoint of
(q, r-1)and(q, r+1)
Returns the average of available predictions, or None if no complete
neighbor pair exists.
