WebMar 24, 2016 · This way we obtain a transformed ray which we can intersect with an AABB. Once an intersection point is found, we need to transform this back to world space via the inverse transformation (i.e. local-to-world transformation). In practice an nAABB is thus expressed as an AABB with a pair of world-to-local and local-to-world transformation … WebFeb 6, 2014 · You could project the AABB on the plan which is orthonormal to the direction of the ray, then resolve the problem of intersection of a 2D sphere with the projected …

It split the structure in multiple Axis-Aligned Bounding-Box (or AABB) which increase the performance of the program by reducing time to find the closest intersection. An AABB can be represented as a 3D rectangle.

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).
