Renders three null geodesic light cones at different positions in a Majumdar-Papapetrou spacetime with two extremally charged black holes. Each cone is constructed by integrating null geodesics from a source point and sweeping over initial directions to form a parametric surface. The composition of multiple cones reveals how the causal structure of spacetime varies with position near the black holes.
