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()

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

Returns:

position of impact.

Since:

1.0

getResponse

public IPoint3D getResponse()

Gets a the response displacement vector .
If an impact happend, return a vector that can be used recursivly to perform sliding or bouncing displacement.

Returns:

response displacement vector.

Since:
