NAME

vpGetMatrix - retrieve the contents of a transformation matrix  

SYNOPSIS

vpResult

vpGetMatrix(vpc, matrix_code, matrix)
vpContext *vpc;
int matrix_code;
vpMatrix4 matrix;
 

ARGUMENTS

vpc
VolPack context from vpCreateContext.
matrix_code
A code specifying one of the VolPack transformation matrices (VP_MODEL, VP_VIEW, VP_PROJECT or VP_SCREEN).
matrix
Matrix for storing the result.
 

DESCRIPTION

vpGetMatrix retrieves the contents of one of the transformation matrices (see vpCurrentMatrix(3)). The special code VP_SCREEN causes the function to compute the transformation from object coordinates to image coordinates and return a matrix describing this transformation.
