Struct ViewportFrame 

#[non_exhaustive]
pub struct ViewportFrame {
    pub background_color: Option<[f32; 4]>,
    pub show_grid: bool,
    pub grid_cell_size: f32,
    pub grid_half_extent: f32,
    pub grid_y: f32,
    pub is_2d: bool,
    pub show_axes_indicator: bool,
    pub overlay_quads: Vec<OverlayQuad>,
}

Viewport presentation settings for one frame.

Groups background, grid, axes indicator, and overlay state — the viewport chrome that is independent of world-space content.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

background_color: Option<[f32; 4]>

Optional background/clear color [r, g, b, a]. None = adapter default.

show_grid: bool

Whether to render the ground-plane grid. Default: false.

grid_cell_size: f32

Grid cell size in world units. Zero = camera-distance-based adaptive spacing.

grid_half_extent: f32

Half-extent of the grid in world units. Zero = 1000 (effectively infinite).

grid_y: f32

World-space Y coordinate of the grid plane (3D mode only). Default: 0.0.

is_2d: bool

Whether the simulation is 2D (affects grid plane orientation). Default: false.

show_axes_indicator: bool

Whether to draw the axes orientation indicator overlay. Default: true.

overlay_quads: Vec<OverlayQuad>

Overlay quads to render this frame.

Trait Implementations

impl Default for ViewportFrame

fn default() -> Self

Returns the “default value” for a type.
