{wiki=Line–sphere_intersection}
The line-sphere intersection problem involves determining the points at which a line intersects a sphere in three-dimensional space. This is a common problem in fields such as computer graphics, physics, and geometric modeling. To describe this geometrically, we have: 1. **Sphere**: A sphere in 3D space can be defined by its center \\( C \\) and its radius \\( r \\).
