Implementations§

Source §

impl VolumeViewState

Source

pub fn orbit(&mut self, delta_x: f64, delta_y: f64)

Orbits the virtual camera around the volume center.

Source

pub fn pan(&mut self, delta_x: f64, delta_y: f64)

Pans the camera in the view plane.

Source

pub fn zoom_by(&mut self, factor: f64)

Applies a multiplicative zoom factor.

Source

pub fn ensure_transfer_window(&mut self, scalar_min: f64, scalar_max: f64)

Ensures that the state has a reasonable transfer window for the scalar range.

Source

pub fn transfer_window(&self, scalar_min: f64, scalar_max: f64) -> (f64, f64)

Returns the active transfer window or a derived default.

Source

pub fn set_transfer_window( &mut self, center: f64, width: f64, scalar_min: f64, scalar_max: f64, )

Updates the transfer window with clamping.

Source

pub fn reset(&mut self)

Resets the volume viewport state back to defaults.
