Struct ViewFrame 

pub struct ViewFrame {
    pub target: [f64; 3],
    pub right: [f64; 3],
    pub up: [f64; 3],
    pub forward: [f64; 3],
}

The saved camera as an orthonormal frame: right / up span the projection plane, forward runs eye → target. Points are measured from the camera’s TARGET, which is the point the placement positions on the paper.

Fields

target: [f64; 3]

right: [f64; 3]

up: [f64; 3]

forward: [f64; 3]

Implementations

impl ViewFrame

pub fn of(camera: &PmiCamera) -> ViewFrame

The frame of a saved camera. Mirrors crate::view::ViewCamera::basis exactly (right = forward × up, true up = right × forward), so a sheet view is oriented the way the viewport showed it.

pub fn to_view(&self, p: [f64; 3]) -> [f64; 3]

(x, y, depth) in view space: x right, y UP, depth along the viewing direction from the target plane (larger = further from the eye).
