Compute_Matrix_Inverse


Functions

HC_BOOLEAN Compute_Matrix_Inverse (const float *matrix, float *out_matrix)

Function Documentation

HC_BOOLEAN Compute_Matrix_Inverse ( const float *  matrix,
float *  out_matrix 
)

Parameters:
matrix - Input transformation matrix.
out_matrix - Output transformation matrix, returned to the caller. Can point to the same place as matrix.
Returns:
success

DETAILS

Compute_Matrix_Inverse() takes a general 4x4 transformation and computes its inverse. If the matrix is singular, the out_matrix will be unchanged and false will be returned.

NOTES

If the matrix is singular, Compute_Matrix_Determinant() would return zero. The adjoint (see Compute_Matrix_Adjoint() ) is similar and will always be defined, even for singular matrices. Consider using that instead where applicable.
