Method Detail

resetImpact

public void resetImpact()

Reset object.
reset to object default value.

Returns:

interface to acces to x,y,z components of the x axis (ax)

Since:

1.0

isImpact

public boolean isImpact()

Gets the impact result.

Returns:

true if an impact happen.

Since:

1.0

getDistance

public double getDistance()

Gets the distance to impact.
If an impact happened, return the distance to this impact.

Returns:

distance to the impact in scene unit.

Since:

1.0

getSlideDistanceOver

public double getSlideDistanceOver()

Gets how much the hitted plane is traversed.
If an impact happened, return the distance over the plane (shortest distance).

Returns:

distance over the plane for the last move.

Since:

1.0

getSlidePlane

public IPoint3D getSlidePlane()

Gets the hitted face plane normal.
If an impact happened, return normal of the hitted face plane, normal contain the parameter a,b,c of the plane equation: a*x+b*y+c*z+d=0.

Returns:

normal of the hitted face plane.

Since:

1.0

getSlidePlaneOffset

public double getSlidePlaneOffset()

Gets the plane "d" parameter in the equation a*x+b*y+c*z+d=0 for the hitted face.
If an impact happened, return the offset value for the hitted face plane equation.

Returns:

offset of the hitted face plane.

Since:

1.0

getPosition

public IPoint3D getPosition()

Gets the impact position.
If an impact happened, return the position of that impact.

Returns:

position of impact.

Since:

1.0

getSlideResponse

public IPoint3D getSlideResponse()

Gets a new displacement vector to perform sliding.
If an impact happend, return a vector that can be used recursivly to perform sliding displacement.

Returns:

sliding displacement vector.
