Constructor & Destructor Documentation

VO ( Vector2  offset,
Vector2  p0,
Vector2  dir,
float  weightFactor 
)

Creates a VO to avoid the half plane created by the point p0 and has a tangent in the direction of dir.

Parameters
p0a point on the half plane border
dirthe normalized tangent to the half plane
VO ( Vector2  offset,
Vector2  p1,
Vector2  p2,
Vector2  tang1,
Vector2  tang2,
float  weightFactor 
)

Creates a VO to avoid the three half planes with {point, tangent}s of {p1, p2-p1}, {p1, tang1}, {p2, tang2}.

tang1 and tang2 should be normalized.

VO ( Vector2  center,
Vector2  offset,
float  radius,
Vector2  sideChooser,
float  inverseDt,
float  weightFactor 
)

Creates a VO for avoiding another agent.

Member Function Documentation

static float Det ( Vector2  a,
Vector2  dir,
Vector2  p 
)
static

Returns a negative number of if p lies on the left side of a line which with one point in a and has a tangent in the direction of dir.

The number can be seen as the double signed area of the triangle {a, a+dir, p} multiplied by the length of dir. If length(dir)=1 this is also the distance from p to the line {a, a+dir}.

static bool Left ( Vector2  a,
Vector2  dir,
Vector2  p 
)
static

Returns if p lies on the left side of a line which with one point in a and has a tangent in the direction of dir.

Also returns true if the points are colinear.
