Struct OpenXrQuadPointerMapper

pub struct OpenXrQuadPointerMapper;

Stateless world-ray mapper for one OpenXR quad layer.

Examples

use ailloli_ui_core::Size;
use ailloli_ui_openxr::{OpenXrQuadLayerOptions, OpenXrQuadPointerMapper};
use ailloli_ui_openxr::math::Vec3;
let point = OpenXrQuadPointerMapper::ray_to_logical_point(Vec3::default(), Vec3::new(0.0, 0.0, -1.0), &OpenXrQuadLayerOptions::default(), Size::new(1024.0, 576.0));
assert_eq!(point.map(|p| (p.x, p.y)), Some((512.0, 288.0)));

Implementations

impl OpenXrQuadPointerMapper

pub fn ray_to_logical_point( ray_origin: Vec3, ray_direction: Vec3, layer: &OpenXrQuadLayerOptions, logical_size: Size, ) -> Option<Point>

Intersects a world ray and returns a top-left-origin logical point.

Returns None for parallel rays, hits behind the origin, or points beyond the finite quad. Layer axes are derived from its quaternion and its physical width/height are clamped to at least one millimetre before halving.

Examples

use ailloli_ui_core::Size;
use ailloli_ui_openxr::{OpenXrQuadLayerOptions, OpenXrQuadPointerMapper};
use ailloli_ui_openxr::math::Vec3;
let point = OpenXrQuadPointerMapper::ray_to_logical_point(Vec3::default(), Vec3::new(0.0, 0.0, -1.0), &OpenXrQuadLayerOptions::default(), Size::new(100.0, 50.0)).unwrap();
assert_eq!((point.x, point.y), (50.0, 25.0));

pub fn sample_from_ray( source_id: u64, ray_origin: Vec3, ray_direction: Vec3, trigger_pressed: bool, layer: &OpenXrQuadLayerOptions, logical_size: Size, ) -> OpenXrPointerSample

Creates a hit/miss pointer sample from a world ray.

Hit depth is deliberately None; this mapper preserves logical routing only. Source ID and pressed state are preserved verbatim; scroll is zero.

Examples

use ailloli_ui_core::Size;
use ailloli_ui_openxr::{OpenXrPointerHit, OpenXrQuadLayerOptions, OpenXrQuadPointerMapper};
use ailloli_ui_openxr::math::Vec3;
let sample = OpenXrQuadPointerMapper::sample_from_ray(7, Vec3::default(), Vec3::new(0.0, 0.0, -1.0), true, &OpenXrQuadLayerOptions::default(), Size::new(100.0, 50.0));
assert!(matches!(sample.hit, OpenXrPointerHit::Hit(_)) && sample.trigger_pressed);

pub fn miss_sample(source_id: u64) -> OpenXrPointerSample

Creates an unpressed miss sample with zero scroll.

Examples

use ailloli_ui_openxr::{OpenXrPointerHit, OpenXrQuadPointerMapper};
let sample = OpenXrQuadPointerMapper::miss_sample(9);
assert_eq!(sample.hit, OpenXrPointerHit::Miss);
assert!(!sample.trigger_pressed);
