Member Function Documentation

void rdBodyConstraint::clear (   )

Clear all point constraints. See also: rdPointConstraint::clear();

void rdBodyConstraint::constructConstraintsForPoint1 (   )

Construct the constraint directions for point 1. Two constraint directions are set for point 1 orthogonal to the vector directed from point 0 to point 1. Note that it is assumed that the constraint directions for point 0 have already been set properly.

void rdBodyConstraint::constructConstraintsForPoint2 (   )

Construct the constraint directions for point 2. One constraint direction is set for point 2 orthogonal to the vector directed from point 0 to point 1 and the vector from point 1 to point 2. Note that it is assumed that the constraint directions for point 0 and Point 1 have already been set properly.

int rdBodyConstraint::getID (   )

Get the ID of this body constraint. Returns: ID of this body constraint.

int rdBodyConstraint::getNC (   )

Get the number of non-zero constraint directions. Returns: Number of non-zero constraint directions.

rdPointConstraint * rdBodyConstraint::getPC (  int  aI  )

Get a pointer to a point constraint. Parameters: aI  Index of the desired point constraint. Returns: Pointer to point constraint at index position aI.

void rdBodyConstraint::setID (  int  aID  )

Set the ID of this body constraint. Parameters: aID  ID of this body constraint.
