Detailed Description

Implements IRayPicker to provide ray intersection query against all collision mesh resources provided by the construction-injected ICollisionBvhProvider instance

Member Function Documentation

bool Eegeo::Collision::CollisionMeshRayPicker::TryGetRayIntersection ( const Eegeo::dv3 &  rayOrigin, const Eegeo::dv3 &  rayDirection, Eegeo::dv3 &  out_ecefIntersectionPoint, double &  out_param  )

virtual

Performs a ray intersection query against the triangles of all collision mesh resources obtained from a query to the constructor-provided ICollisionBvhProvider instance. If the ray intersects the mesh at multiple points, finds the first intersection (closest to rayOrigin). If an intersection is found, returns true, with intersection information passed in out parameters.

Parameters

rayOrigin	start point of ray, in Ecef coordinates
rayDirection	normalised direction of ray, in Ecef coordinates
out_ecefIntersectionPoint	[out] closest point of intersection in Ecef coordinates if successful, else zero vector
out_param	[out] distance in metres from rayOrigin to out_ecefIntersectionPoint if successful, else zero

Returns

true if intersection found, else false
