WebComputing the intersection of a ray with an AABB is quite simple. All we need is to remember that a straight line can be defined as: y = m x + b. In mathematics, the m term is called the slope (or gradient) and is … WebTry this algorithm: the sphere collides with AABB if the sphere lies (or partially lies) on inside side of all planes of the AABB.Inside side of plane means the half-space directed to AABB center.. So, you should check for sphere vs. axis-aligned plane intersections for each of 6 AABB planes (xmin/xmax, ymin/ymax, zmin/zmax).
