NAME

DoCameraMatrix − Create a camera matrix studio attribute object. 

SYNOPSIS

C:

DtObject DoCameraMatrix(matrix)
DtMatrix4x4 matrix;

FORTRAN:

INTEGER∗4 DOCMX(MATRIX)
REAL∗8 MATRIX(4,4)

DESCRIPTION

DoCameraMatrix creates a camera matrix studio attribute object.  When DoCameraMatrix is executed in a definition group, its parameter matrix replaces the camera projection matrix used for all subsequently executed camera objects. 

The argument matrix is an arbitrary 4x4 matrix; singular matrices will cause fatal errors.  DoCameraMatrix is intended for advanced users needing special effects.  Most useful camera matrices are obtainable using by DoProjection <DOPRJ>, DoParallel <DOPAR>, or DoPerspective <DOPER>. 

ERRORS

DoCameraMatrix will fail if the matrix is singular. 

[WARNING - non-invertible matrix]
