Struct WidgetOverlay 

Source 
pub struct WidgetOverlay {
    pub main: Overlay,
    pub plane_tri_verts: usize,
    pub viewcube: Option<ViewCubeFrame>,
}
Expand description

A whole frame’s worth of overlay-widget geometry, ready for the render core’s overlay pass: the main overlay (datums / dimensions / curves / transform gizmo, full-viewport) + the optional ViewCube (own mini-camera + corner rect).

Fields§

§main: Overlay§plane_tri_verts: usize

Number of LEADING main.tris vertices belonging to the datum/construction planes (drawn with a no-depth-write pipeline so they never occlude the gizmos/dimensions that follow). The remaining tris are the gizmo geometry.

§viewcube: Option<ViewCubeFrame>

Implementations§

Source§

impl WidgetOverlay

Source

pub fn is_empty(&self) -> bool

Nothing to draw (skip the overlay passes entirely).

Source

pub fn world_bbox(&self) -> Aabb

The world-space AABB of the MAIN overlay (datums, axes, frames, curves, dimensions, transform gizmo, general groups) — folded into the camera depth-range fit so construction geometry beyond the solids never clips. EXCLUDES the ViewCube: it lives in the separate viewcube field and is drawn with its own mini-camera, so its coords are NOT world space — bboxing them would corrupt the fit. Point groups are already expanded into main.tris (push_point_quad), so tris + lines cover everything. Empty when the main overlay is empty. A single vertex absurdly far out (|coord| > 1e6) is skipped rather than unioned, so a pathological “infinite” helper can’t blow the depth window open (world axes are screen-constant and finite, but be defensive).
