pub fn encode_heights(elevations: &[f64], width: u32, height: u32) -> Vec<u8> ⓘExpand description
Encode a row-major width × height elevation grid into little-endian
u16 bytes (width * height * 2 bytes).
Rows are expected north → south, columns west → east (Cesium’s convention).
§Panics
Panics if elevations.len() < (width * height) as usize.
