Notice how the artifact on the sphere remains symmetrical. More importantly, note what happens if the sphere is on the same height as the Camera and make it bigger; 3. This might be a controversial statement, but to me it appears as if the Ray Sphere Intersection only fails in the center / middle of the sphere.
In analytic geometry, a line and a sphere can intersect in three ways: 1. No intersection at all 2. Intersection in exactly one point 3. Intersection in two points. WebRay-Sphere Intersection Solve quadratic equations for t Ray-Sphere Intersection Intersection point: Normal (for sphere, this is same as coordinates in sphere frame of reference, useful other tasks) Ray-Triangle Intersection One approach: Ray-Plane intersection, then check if inside triangle Plane equation: A B C Ray-Triangle Intersection
WebRay intersection in software • Scenes usually have many objects • Need to find the first intersection along the ray – that is, the one with the smallest positive t value • Loop over objects – ignore those that don’t intersect – keep track of the closest seen so far – Convenient to give rays an ending t value for this purpose (then
