WebThe method described above consists of two distinct parts: spherical-caps/triangle and cylinder/triangle intersection tests. The combination of these two algorithms forms a cylinder-with-spherical-caps/triangle intersection test, which corresponds to finding collisions between a particle’s trajectory and the environment. http://paulbourke.net/geometry/circlesphere/

WebSep 27, 2024 · To hit a cylinder we notice that: A = C + V*m ( P-A ) V = 0 len ( P-A ) = r where m is a scalar that determines the closest point on the axis to the hit point. The P-A vector is perpendicular to V, which guarantees the closest distance to the axis. P-A is the cylinder's radius. Solution: (P-C-V*m) V = 0 because p -c is perpendicular to V.

Intersect the top and bottom circles of the cylinder with the plane of the triangle. Check if the intersection points are inside the triangle. The ray is defined by an origin point and a direction vector . Every point on the ray can be expressed by , where the parameter ranges from zero to infinity. The triangle is defined by three vertices, named , , . The plane that the triangle is on, which is needed to calculate the ray-triangle intersection, is defined by a point on the plane, such as , and a vector that is orthogonal to every point on that plane, such as the cross product between the vector from to and the vector from to :
