Webray-disk-intersection. Calculate the intersection of a ray and a disk or plane in three dimensions. A disk is generally defined by a position (the disk center's position), a normal and a radius. First we can test if the ray intersects the plane in which lies the disk. Then … WebRay-Disk Intersection. A ray is only defined for t ≥ 0, so we can simply check if t is nonnegative, and accept or reject the intersection. Line Segment–Disk Intersection. We …

If Δ = 0, the ray is … WebIntersecting a disk • Intersecting circles is similar to intersecting quadrilaterals • The extent check, after computing the intersection point, becomes one of using the circle equation • Consider a circle lying on the z=0 plane. If the ray intersects the z=0 plane, it also intersects the circle if: x2 +y2 −1 ≤ 0

WebIn the thinner disk model (M5), the shocks break out of the disk earlier due to the shorter distance from the disk midplane to the AGN surface. The duration of the X-ray emission is also shorter than in the ducial model (cyan line in Fig.6a), since t sph is shorter. In model M6, the high orbital velocity of the star in-
