Do we trace it until the ray hits the "Boundary" of the world so t does not go to infinity?

Following the previous question, what happens if the shape we want to intersect the plane with is clipped at the "boundary?" Wouldn't that gives us the wrong result for, say, an inside-outside test?

BlueCat

Is the unit direction here similar as what we used (tangent.normalize() or normal.normalize()) in a2? Is it the amount of increase for each unit in the certain direction?

Why would ray tracing perform better than rasterization? What makes the difference?

Can ray tracing be used with explicit representations?
