Function Documentation

bool FCOLLADA_EXPORT IsEquivalent (  const FMMatrix44 &  m1, const FMMatrix44 &  m2 )

Matrix equality comparison function. Parameters: m1  A first matrix. m2  A second matrix. Returns: Whether the given matrices are equal.

FMMatrix44 FCOLLADA_EXPORT operator * (  float  a, const FMMatrix44 &  m )

Scalar multiplication with float and FMMatrix44. All the components of the matrix get uniformly multiplied by the scalar. EDITOR NOTE: Is this functionality even useful? I cannot think of a reason this function would be used. Parameters: a  A scalar. m  A matrix. Returns: The resulting matrix.

FMVector4 FCOLLADA_EXPORT operator * (  const FMMatrix44 &  m, const FMVector4 &  v )

Transforms a four-dimensional vector by a given matrix. If the 'w' value of the vector is 1.0, this is a coordinate transformation. If the 'w' value of the vector is 0.0, this is a vector transformation. Parameters: m  A matrix. v  A vector. Returns: The FMVector4 representation of the resulting vector.

FMMatrix44 FCOLLADA_EXPORT operator * (  const FMMatrix44 &  m1, const FMMatrix44 &  m2 )

Matrix multiplications. Effectively concatenates matrix transformations. FCollada does left-multiplication of matrices. Parameters: m1  A first matrix. m2  A second matrix. Returns: The concatenation of the two matrix transformations.

FMMatrix44& operator *= (  FMMatrix44 &  m1, const FMMatrix44 &  m2 )  [inline]

Left-multiplies a given matrix, in-place. This function effectively concatenates a transformation into a transform matrix. Parameters: m1  The in-place multiplied matrix. m2  A matrix transformation. Returns: The in-place multiplied matrix.
