NAME CAD::Drawing::Manipulate::Transform - Matrix methods for CAD::Drawing DESCRIPTION Provides 3D transformation methods (based on traditional matrix algorithms) for Drawing.pm objects. Coordinate System All of these methods assume a RIGHT-HANDED coordinate system. If you are using a left-handed coordinate system, you are going to have trouble, trouble, trouble.

SEE ALSO CAD::Drawing CAD::Drawing::Calculate CAD::Calc Math::Vec Math::Matrix Changes 0.01 First public release Methods Transform $drw->Transform($addr, \%opts); Options: normal_ready => [@normal_vec] # no-questions-asked normal vector input build_matrix Builds a linear transformation matrix according to %opts; $mat = build_matrix(%opts); Options: LTM => $ltm # pass-through for pre-built matrices R => [$rX, $rY, $rZ] # rotation about each axis T => [$tX, $tY, $tZ] # translation along each axis S => [$sX, $sY, $sZ] # scaling along each axis Units: Scaling is in decimal (e.g. $sX = 0.9 will scale by 90%) NewMat Calls Math::MatrixReal->new_from_rows([@_]) see Math::MatrixReal for methods which can be applied to the returned object. $mat = NewMat(@rows); transform_pt Applies matrix multiplication to linearly transform @pt by $mat. This eliminates the tedium of making new matrices just to multiply one point. @pt = transform_pt(\@pt, $mat); rotation_matrices Returns a list of matrices corresponding to ($rX, $rY, $rZ) Rotation is in ccw radians about each axis (right-hand rule) except that they may be specified in degrees with $angle . "d" @rotations = rotation_matrices($rX, $rY, $rZ); Resulting matrix will perform rotations in Z,Y,X order. translation_matrix Builds a linear transformation tranlation matrix from @trans, where @trans = ($trX, $trY, $trZ). $mat = translation_matrix(@trans); scaling_matrix Builds a linear tranformation matrix from @scales, where @scales = ($sX, $sY, $sZ). $mat = scaling_matrix(@scales);
