Math::Geometry is a Perl module that implements classic geometry methods. It should be considered alpha software and any feedback at all is greatly appreciated. The following methods are available:<br /><br />vector_product.<br /><br />Also known as the cross product, given two vectors in Geometry space, the vector_product of the two vectors, is a vector which is perpendicular to the plane of AB with length equal to the length of A multiplied by the length of B, multiplied by the sin of @, where @ is the angle between the two vectors.<br /><br />triangle_normal<br /><br />Given a triangle ABC that defines a plane P. This function will return a vector N, which is a normal to the plane P.<br /><br /> ($Nx,$Ny,$Nz) =<br /> triangle_normal(($Ax,$Ay,$Az),($Bx,$By,$Bz),($Cx,$Cy,$Cz));<br /><br />zplane_project<br /><br />Project a point in Geometry space onto a plane with the zaxis as the normal, at a distance d from z=0.<br /><br /> ($x2,$y2,$z2) = zplane_project ($x1,$y1,$z1,$d);<br /><br />rotx<br /><br />Rotate about the x axis r radians.<br /><br /> ($x2,$y2,$z2) = rotx ($x1,$y1,$z1,$r);<br /><br />roty<br /><br />Rotate about the y axis r radians.<br /><br /> ($x2,$y2,$z2) = roty ($x1,$y1,$z1,$r);<br /><br />rotz<br /><br />Rotate about the z axis r radians.<br /><br /> ($x2,$y2,$z2) = rotz ($x1,$y1,$z1,$r);<br /><br />deg2rad<br /><br />Convert degree's to radians.<br /><br />rad2deg<br /><br />Convert radians to degree's.<br />pi<br /><br />Returns an approximate value of Pi, the code has been cribed from Pg146, Programming Perl 2nd Ed.<br /><br />SYNOPSIS<br /><br /> use Math::Geometry;<br /><br /> @P2=rotx(@P1,$angle);<br /> @P3=rotx(@P1,$angle);<br /> @N =triangle_normal(@P1,@P2,@P3);<br /> @ZP=zplane_project(@P1,$d);
