Method Details

convert

public static DMatrixRMaj convert(ConicGeneral_F64 src,
 @Nullable
 @Nullable DMatrixRMaj dst)

Converts symmetric 3x3 matrix back into a conic.

        [A    B/2  D/2]
  dst = [B/2  C    E/2]
        [D/2  E/2  F  ]
 

convert

public static ConicGeneral_F64 convert(DMatrix3x3 src,
 @Nullable
 @Nullable ConicGeneral_F64 dst)

Converts symmetric 3x3 matrix back into a conic. Only the upper right portion of src is read.

     A = DST(0,0)
     B = DST(0,1)*2
     D = DST(0,2)*2
     C = DST(1,1)
     E = DST(1,2)*2
     F = DST(2,2)
 

convert

public static DMatrix3x3 convert(ConicGeneral_F64 src,
 @Nullable
 @Nullable DMatrix3x3 dst)

Converts the conic into a symmetric 3x3 matrix

        [A    B/2  D/2]
  dst = [B/2  C    E/2]
        [D/2  E/2  F  ]
 

convert

public static ConicGeneral_F64 convert(DMatrixRMaj src,
 @Nullable
 @Nullable ConicGeneral_F64 dst)

Converts symmetric 3x3 matrix back into a conic. Only the upper right portion of src is read.

     A = DST(0,0)
     B = DST(0,1)*2
     D = DST(0,2)*2
     C = DST(1,1)
     E = DST(1,2)*2
     F = DST(2,2)
 

convert

public static ParabolaGeneral_F64 convert(ConicGeneral_F64 src,
 @Nullable
 @Nullable ParabolaGeneral_F64 dst)

Converts the conic into a parabola. If the conic isn't a parabola then it is converted into one by adjusting the value of B.

Parameters:

src - (Input) Conic

dst - (Output) Optional storage for converted parabola

Returns:

Parabola

convert

public static ConicGeneral_F64 convert(ParabolaGeneral_F64 src,
 @Nullable
 @Nullable ConicGeneral_F64 dst)

Converts the parabola into a conic.

Parameters:

src - (Input) Parabola

dst - (Output) Optional storage for converted conic

Returns:

Conic
