Struct View3D 

pub struct View3D {
    pub azimuth: f64,
    pub elevation: f64,
}

Viewing angles for 3D projection.

Fields

azimuth: f64

Azimuth angle in degrees (rotation around Z-axis). Default: -60.

elevation: f64

Elevation angle in degrees (rotation from XY-plane). Default: 30.

Implementations

impl View3D

pub fn front_bottom_corner(&self) -> (f64, f64)

Find the floor-face corner closest to the viewer (smallest depth). Returns the normalized (x, y) signs of that corner, e.g. (0.5, -0.5). This is the “open front corner” where axes originate.

For positive elevation the floor is z=-0.5; for negative elevation (viewing from below) the floor is z=+0.5.

pub fn auto_z_axis_right(&self) -> bool

Derive which screen side the Z axis should appear on for this view.

When the front corner is at fc_x >= 0 (e.g. default azimuth -60°), the rightmost back edge is the natural Z axis position. When the view is mirrored (fc_x < 0, e.g. azimuth +60°), the leftmost edge reads more naturally. This matches matplotlib’s default behaviour across all azimuths without the user needing to know about it.
