d 2 + β 2 t 2 = r 2. gives the two intersections of the infinite cylindre with the infinite ray. You can restrict to t ≥ 0 for a half-ray. If the cylindre has finite extent, the two basis will have the equations z = z m i n and z = z m a x (wrt …

Ray Tracing - Bounding Volumes • Place simple objects (i.e., sphere or box) around complex objects – Suitability depends on object being enclosed! • Do initial intersection tests on bounding objects. • If ray intersects bounding volume, then test complex bounded object • Can be nested 2 Ray Tracing - Bounding Volumes [Watt/Watt,235]

Ray-Plane Intersection • Intersection means both equations are satisfied • So, insert explicit equation of ray into implicit equation of plane & solve for t P(t) = R o + t * R d H(P) = n·P + D = 0 n·(R o + t * R d ) + D = 0 t = -(D + n P(t)·R o ) / n·R d Done! 10 Ray-Plane Intersection
