Ranges

This is the api for all the range objects.

class pyscan.Halfplane(pt)

This is a range representing a halfplane. Internally it uses a homogenous coordinate and is usually oriented downwards.

Parameters:pt – Point
Halfplane.get_coords()

Returns the internal Point representation of this Halfplane.

Return type:Point
Halfplane.contains(pt)

Checks to see if the halfplane contains the point. Internally uses Point.below_closed.

Parameters:pt – Point
Return type:boolean
Halfplane.intersects_segment(p1, p2)

Checks to see if the halfplane intersects the line segment represented by p1 and p2. Internally uses Point.crosses.

Parameters:
  • p1 – Point
  • p2 – Point
Return type:

boolean
Halfplane.intersects_trajectory(traj)

Checks to see if the halfplane intersects the trajectory represented by traj.

Parameters:traj – Trajectory
Return type:boolean
class pyscan.Halfspace(pt)

This is a range representing a halfspace in 3d. Internally it uses a homogenous coordinate and is usually oriented downwards.

Parameters:pt – Point3
Halfspace.get_coords()

Returns the internal Point3 representation of this Halfplane.

Return type:Point3
Halfplane.contains(pt)

Checks to see if the halfplane contains the point. Internally uses Point.below_closed.

Parameters:pt – Point3
Return type:boolean
Halfspace.intersects_segment(p1, p2)

Checks to see if the halfplane intersects the line segment represented by p1 and p2. Internally uses Point.crosses.

Parameters:
  • p1 – Point3
  • p2 – Point3
Return type:

boolean
class pyscan.Disk(origin, radius)

This is a range representing a disk. Internally it uses a point for its center and a radius around that center.

Parameters:
  • origin – Point
  • radius – double
Disk.getOrigin()

Returns the internal Point representation of the disk center.

Return type:Point
Disk.getRadius()

Returns the radius of this disk.

Return type:double
Disk.contains(pt)

Checks to see if the Disk contains the point.

Parameters:pt – Point
Return type:boolean
Disk.intersects_segment(p1, p2)

Checks to see if the Disk intersects the line segment represented by p1 and p2.

Parameters:
  • p1 – Point
  • p2 – Point
Return type:

boolean
Disk.intersects_trajectory(traj)

Checks to see if the disk intersects the trajectory represented by traj.

Parameters:traj – Trajectory
Return type:boolean
class pyscan.Rectangle(upX, upY, lowX, lowY)
