Struct ViewTransform 

#[repr(C)]
pub struct ViewTransform {
    pub zoom: f32,
    pub pan: [f32; 2],
    pub _pad: f32,
}

The shared camera transform every scene family applies (ADR-0018): a uniform zoom about the frame centre, then a pan, in world space before the aspect divide. Identity (zoom = 1, pan = 0) leaves geometry exactly where a scene placed it, so a preset that binds none of zoom/pan_x/pan_y is unchanged. #[repr(C)] + Pod so it uploads straight into a line-renderer uniform slot. Rotate is reserved for a follow-up (ADR-0018 reserves it).

Defined here for Phase 1 (the line scenes are the walking skeleton); Phase 2 threads the same transform through the fragment and swarm scenes.

Fields

zoom: f32

Uniform scale about the frame centre (1.0 = no zoom).

pan: [f32; 2]

Pan offset in world units (x, y), applied after the zoom.

_pad: f32

Padding to fill a 16-byte uniform slot (unused).

Trait Implementations

impl Clone for ViewTransform

fn clone(&self) -> ViewTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewTransform

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

Formats the value using the given formatter.

impl Default for ViewTransform

fn default() -> Self

The identity view: no zoom, no pan.

impl PartialEq for ViewTransform

fn eq(&self, other: &ViewTransform) -> 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.

impl Zeroable for ViewTransform

fn zeroed() -> Self

Calls zeroed.

impl Copy for ViewTransform

impl Pod for ViewTransform

impl StructuralPartialEq for ViewTransform
