Public Member Functions | |
| EZ_DECLARE_POD_TYPE () | |
| EZ_ALWAYS_INLINE Type & | Element (ezInt32 iColumn, ezInt32 iRow) |
| EZ_ALWAYS_INLINE Type | Element (ezInt32 iColumn, ezInt32 iRow) const |
| ezMat3Template () | |
| Default Constructor DOES NOT INITIALIZE the matrix, at all. | |
| void | GetAsArray (Type *out_pData, ezMatrixLayout::Enum layout) const |
| Copies the 9 values of this matrix into the given array. 'layout' defines whether the data should end up in column-major or row-major format. | |
| void | SetZero () |
| Sets all elements to zero. | |
| void | SetIdentity () |
| Sets all elements to zero, except the diagonal, which is set to one. | |
| void | Transpose () |
| Transposes this matrix. | |
| const ezMat3Template< Type > | GetTranspose () const |
| Returns the transpose of this matrix. | |
| ezResult | Invert (Type fEpsilon=ezMath::SmallEpsilon< Type >()) |
| Inverts this matrix. Return value indicates whether the matrix could be Inverted. | |
| const ezMat3Template< Type > | GetInverse (Type fEpsilon=ezMath::SmallEpsilon< Type >()) const |
| Returns the inverse of this matrix. | |
| bool | IsZero (Type fEpsilon=ezMath::DefaultEpsilon< Type >()) const |
| Checks whether all elements are zero. | |
| bool | IsIdentity (Type fEpsilon=ezMath::DefaultEpsilon< Type >()) const |
| Checks whether this is an identity matrix. | |
| bool | IsValid () const |
| Checks whether all components are finite numbers. | |
| bool | IsNaN () const |
| Checks whether any component is NaN. | |
| ezVec3Template< Type > | GetRow (ezUInt32 uiRow) const |
| Returns all 3 components of the i-th row. | |
| void | SetRow (ezUInt32 uiRow, const ezVec3Template< Type > &vRow) |
| Sets all 3 components of the i-th row. | |
| ezVec3Template< Type > | GetColumn (ezUInt32 uiColumn) const |
| Returns all 3 components of the i-th column. | |
| void | SetColumn (ezUInt32 uiColumn, const ezVec3Template< Type > &vColumn) |
| Sets all 3 components of the i-th column. | |
| ezVec3Template< Type > | GetDiagonal () const |
| Returns all 3 components on the diagonal of the matrix. | |
| void | SetDiagonal (const ezVec3Template< Type > &vDiag) |
| Sets all 3 components on the diagonal of the matrix. | |
| const ezVec3Template< Type > | GetScalingFactors () const |
| Returns the 3 scaling factors that are encoded in the matrix. | |
| ezResult | SetScalingFactors (const ezVec3Template< Type > &vXYZ, Type fEpsilon=ezMath::DefaultEpsilon< Type >()) |
| Tries to set the three scaling factors in the matrix. Returns EZ_FAILURE if the matrix columns cannot be normalized and thus no rescaling is possible. | |
| Type | GetDeterminant () const |
| Computes the determinant of the matrix. | |
| const ezVec3Template< Type > | TransformDirection (const ezVec3Template< Type > &v) const |
| Matrix-vector multiplication, assuming the 4th component of the vector is zero. So, rotation/scaling only. Useful as an optimization. | |
| void | operator*= (Type f) |
| Component-wise multiplication (commutative) | |
| void | operator/= (Type f) |
| Component-wise division. | |
| bool | IsIdentical (const ezMat3Template< Type > &rhs) const |
| Equality Check. | |
| bool | IsEqual (const ezMat3Template< Type > &rhs, Type fEpsilon) const |
| Equality Check with epsilon. | |
