graphics - ray tracing with sphere - Stack Overflow

Substitute these into the equation for the circle x^2 + y^2 + z^2 = 0. This produces a quadratic equation with the variable t. Find the roots of the equation. Now, if you have no real roots, the ray doesn't hit the sphere. If you have one real root then you hit the side of the sphere. If you have two real roots, then you hit the sphere twice.

radius^2 = length(point_on_sphere)^2 = dot(point_on_sphere,point_on_sphere) Now we've reduced the square root business to just dot products. With shorter symbol names: r*r = dot(P,P) Substitute in the ray equation (1) to find the ray/line intersection point: r*r = dot(C+t*D,C+t*D) = dot(C,C) + 2*dot(C,t*D) + dot(t*D,t*D) or using dot product linearity again:

Ray 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
