Cool, whether you choose OpenGL or DirectX, there is a huge amount of 
resource on the web to help get you started.  I don't have any recent 
experience with OpenGL, but DirectX has a lot of documentation included in 
the download, with lots of tutorials and sample projects.

Both OpenGL and DirectX work with 4x4 matrices for everything, so in the end 
your camera is represented by a 4x4 matrix.  If you're good at maths you can 
program these 16 values directly in your code (as I believe you can in POV 
as well), but of course there are built-in functions for creating these 
matrices automatically.  The parameters they take are similar to the ones 
you use in the POV camera block.
