Constructor Detail

b2Mat33

public b2Mat33(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

b2Mat33

public b2Mat33(long size)

Native array allocator. Access with Pointer.position(long).

b2Mat33

public b2Mat33()

The default constructor does nothing (for performance).

b2Mat33

public b2Mat33(@Const @ByRef
               b2Vec3 c1,
               @Const @ByRef
               b2Vec3 c2,
               @Const @ByRef
               b2Vec3 c3)

Construct this matrix using columns.

Method Detail

position

public b2Mat33 position(long position)

Overrides:

position in class Pointer

getPointer

public b2Mat33 getPointer(long i)

Overrides:

getPointer in class Pointer

SetZero

public void SetZero()

Set this matrix to all zeros.

Solve33

@ByVal
public b2Vec3 Solve33(@Const @ByRef
                              b2Vec3 b)

Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.

Solve22

@ByVal
public b2Vec2 Solve22(@Const @ByRef
                              b2Vec2 b)

Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases. Solve only the upper 2-by-2 matrix equation.

GetInverse22

public void GetInverse22(b2Mat33 M)

Get the inverse of this matrix as a 2-by-2. Returns the zero matrix if singular.

GetSymInverse33

public void GetSymInverse33(b2Mat33 M)

Get the symmetric inverse of this matrix as a 3-by-3. Returns the zero matrix if singular.
