void | Append_Modelling_Matrix (const float *array) |
void Append_Modelling_Matrix | ( | const float * | array | ) |
Allows direct manipulation of the matrix transform applied against all picture elements and subsegments in a segment.
array | - Transform matrix provided by the user. Passed by reference in all languages. May need to be transposed in languages other than C. |
Use this routine only if your program organizes and keeps track of the net transformations applied to your objects.
If there was no previous transform, this operation becomes a plain Set_Modelling_Matrix() .
The first, second, and third rows of the fourth column of array must be zero---no "perspective" transformation is allowed. The fourth row of the fourth column is usually 1.0 (it must not be zero.)
