Struct InputFeel 

pub struct InputFeel {
    pub orbit_per_px: f32,
    pub pan_per_px: f32,
    pub dolly_per_scroll: f32,
    pub damping: f32,
    pub natural_scroll: bool,
}

How the camera should feel for this OS / input device — derived from facett-core’s look presets so a macOS trackpad orbits/pinches naturally while a Windows wheel zooms in discrete steps.

Fields

orbit_per_px: f32

Orbit radians per screen pixel of drag.

pan_per_px: f32

Pan world-units per screen pixel (scaled by distance at use site).

dolly_per_scroll: f32

Multiplicative dolly per wheel/scroll unit (e.g. 0.0015 ⇒ gentle).

damping: f32

Damping rate k in 1 - exp(-k·dt). Higher = snappier, lower = floatier.

natural_scroll: bool

Trackpad two-finger scroll is “natural” (content follows fingers) — invert the pan sign so a macOS trackpad pans the right way.

Implementations

impl InputFeel

pub fn macos() -> Self

The macOS trackpad feel: a touch more sensitive, natural-scroll panning, floatier damping (pinch-to-zoom reads as continuous).

pub fn windows() -> Self

The Windows mouse feel.

Trait Implementations

impl Clone for InputFeel

fn clone(&self) -> InputFeel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for InputFeel

impl Debug for InputFeel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InputFeel

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for InputFeel

fn eq(&self, other: &InputFeel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
