Struct TensorField 

pub struct TensorField<'a> { /* private fields */ }

Evaluates a tensor field over a HeightMap, producing orthogonal major/minor direction vectors at any world-space coordinate.

• Major (contour): follows elevation lines — ideal for winding mountain roads.
• Minor (gradient): points up/down the slope — ideal for steep connecting streets.

Implementations

impl<'a> TensorField<'a>

pub fn new(heightmap: &'a HeightMap) -> Self

Creates a tensor field with default sampling parameters.

pub fn with_config(heightmap: &'a HeightMap, config: TensorFieldConfig) -> Self

Creates a tensor field with custom sampling parameters.

pub fn sample(&self, world_x: f32, world_z: f32) -> (Vec2, Vec2)

Samples the tensor field, returning (major, minor) unit direction vectors.
