◆ Check()

bool chrono::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.

Parameters
startray start point
endray end point
[out]infotest result info
