Ray Intersection

High-Level Functions

AsteroidShapeModels.intersect_ray_shape — Function

intersect_ray_shape(ray::Ray, shape::ShapeModel, bbox::BoundingBox) -> RayShapeIntersectionResult

Perform accelerated ray-shape intersection test using bounding box optimization. Uses the Möller–Trumbore algorithm for ray-triangle mesh intersection.

Arguments

ray: Ray
shape: Shape model
bbox: Bounding box of the shape model

Returns

RayShapeIntersectionResult object containing the intersection test result
