pub struct Heatmap {
    pub cols: usize,
    pub rows: usize,
    pub cell_px: f64,
    pub grid: Vec<f64>,
}

A heatmap rendered as a coarse intensity grid over pixel space.

Fields

cols: usize

rows: usize

cell_px: f64

grid: Vec<f64>

Row-major intensity values in [0, 1].

pub fn build(p: &HeatmapParams<'_>) -> Self

Build a heatmap from points, aggregating into cell_px cells.

pub fn at(&self, col: usize, row: usize) -> Option<f64>

Intensity at cell (col, row).
