Raycasting

Raycasting is a computational technique used to determine the intersection of rays (lines extending infinitely in one direction) with objects in a scene, often employed in graphics, simulations, and collision detection. The method involves tracing a ray from a source point, usually defined by an origin O and a direction vector D, and checking if it intersects any objects using parametric equations. For a ray, the equation is:

R(t) = O + t * D

where t ≥ 0 is a scalar defining points along the ray. By solving for t in geometric equations representing objects (e.g., planes, spheres), raycasting identifies intersection points, if any exist. Efficient algorithms optimize these checks to handle complex scenes quickly, making raycasting foundational in rendering and physics engines.
