Gets the point where a track projection crosses a plane. This assumes that the plane is oriented along a cartiesen axis
Inputs:
track -> the track projectection data
point -> point at the center of the plane
face -> enum which defines the orientation/ side of the LAT the plane is on (top=0, -Y, -X, +Y, +X, bottom)
Outputs:
arcLength -> distance along the track where the plane is crossed occurs => hitPoint = track.m_point + arcLength * track.m_dir
localX -> position of the crossing point relative to the plane center
localY
hitPoint -> the point where the track projection crosses the plane
tilePlane(const Track& track, const Tile& tile,
...
arcLength, localX, localY,activeX, activeY, active2D, Point& hitPoint)
Gets the point where a track projection crosses a tile
...
Outputs:
arcLength -> distance along the track where the plane is crossed occurs => hitPoint = track.m_point + arcLength * track.m_dir
localX -> position of the crossing point relative to the plane center
localY
activeX -> position of the crossing point relative to the edge of the active area ( >0 is in active area)
activeY
active2D -> the larger of activeX and activeY
hitPoint -> the point where the track projection crosses the plane
...
plane (+x , +y, -x, -y edges in local frame)
tileEdgePoca(const Track& track, const Tile& tile,
...
arcLength, dist, Point& poca, Vector& vector, int& region)
Gets the point where a track projection (that goes inside a tile) comes closest one of the edges of the tile
...
Outputs:
arcLength -> distance along the track where the plane is crossed occurs => hitPoint = track.m_point + arcLength * track.m_dir
h -> the point where the track projection crosses the plane dist -> the distance of closest approach between the track and the tile edge (in 3D)
poca -> the point of closest approach along the track to the tile edge
vector -> the vector from the poca to the closest point on the tile edge
region -> a code to show which edge of the tile was considered (+y,+x,-y,-x)
tileEdgeCornerPoca(const Track& track, const Tile& tile,arcLength, dist, Point& poca, Vector& vector, int& region)
Gets the point where a track projection (that goes outside a tile) comes closest one of the edges or corners of the tile
Inputs:
track -> the track projectection data
tile -> the geomertical informatio about the tile
Outputs:
arcLength -> distance along the track where the plane is crossed occurs => hitPoint = track.m_point + arcLength * track.m_dir
dist -> the distance of closest approach between the track and the tile edge (in 3D)
poca -> the point of closest approach along the track to the tile edge
vector -> the vector from the poca to the closest point on the tile edge
region -> a code to show which edge of the tile was considered (y,+x,y,-x edges, +, +, --, -+ corners)
