Struct TimeDilationRenderer 

pub struct TimeDilationRenderer {
    pub c: f64,
    pub show_clock_hands: bool,
    pub clock_size: f32,
}

Render clocks with tick rate proportional to proper time rate.

Fields

c: f64

show_clock_hands: bool

clock_size: f32

Implementations

impl TimeDilationRenderer

pub fn new(c: f64) -> Self

pub fn tick_rate(&self, v: f64) -> f32

Compute the apparent tick rate of a clock at velocity v. Returns a fraction of normal tick rate (0 to 1).

pub fn clock_hand_angle(&self, proper_time: f64) -> f32

Compute the clock hand angle for a given proper time. One full rotation = 60 “seconds” of proper time.

pub fn clock_glyph_data( &self, center: Vec2, proper_time: f64, ) -> (Vec<Vec2>, Vec2)

Generate glyph data for a clock face at a position. Returns positions for 12 hour markers and the hand endpoint.

pub fn render_clocks( &self, clocks: &[DilatedClock], positions: &[Vec2], ) -> Vec<(Vec<Vec2>, Vec2)>

Render multiple clocks at different velocities.

Trait Implementations

impl Clone for TimeDilationRenderer

fn clone(&self) -> TimeDilationRenderer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeDilationRenderer

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

Formats the value using the given formatter.
