◆ Check()
| bool chrono::collision::ChRayTest::Check | ( | const real3 & | start, |
| const real3 & | end, | ||
| RayHitInfo & | info | ||
| ) |
Check for intersection of the given ray with all collision shapes in the system.
Uses a variant of the 3D Digital Differential Analyser (Akira Fujimoto, "ARTS: Accelerated Ray Tracing Systems", 1986) to efficiently traverse the broadphase grid and analytical shape-ray intersection tests.
