Compiling ARToolkit on Ubuntu 10.04

Apparently I’ve given more thought on to ARToolkit these days  (mainly due to my research), so that it makes me  attempt different things with it. Consequently I’ll be writing a series of posts pertaining to my small experiments for future references. I know it’s pretty boring stuff, talking about a dull subject again and again… but it merely gives us a sensation when doing it physically (particularly when you have nothing left to do 😉 ). In general everybody feels great when their imaginations turn into a physical realization.

So… enough lecturing & let me keep aside my talking. In today’s post I’ll cover-up the installation of ARToolkit in Ubuntu 10.04. Continue reading “Compiling ARToolkit on Ubuntu 10.04”

Demistifying DSVL Configuration

directx-logoIn my previous post I just mentioned how we can use ARToolkit in conjunction with a 3D rendering engine. The camera connection was made by the ARToolkit via DSVL (DirectShow Video Library) . As I promised, through this post, I’ll expose how we can configure DSVL with its supported parameters.

DSVL is a wrapper for DirectShow which in turn is a part of DirectX. We all know that DirectX is the prominent media framework used in windows platforms. Other than DirectShow, Direct3D and DirectSound also come under the brotherhood of DirectX. So what is the specialty of DirectShow? In computers data can be generated in many places, such as file system, network, TV cards or video cameras etc. And data which is produced at each of these locations take many formats. Therefore front-end applications have to explicitly communicate with these underlying data sources and deal with its formats. Obviously this would be pretty cumbersome and overwhelmingly incompatible with different hardware devices. This is where DirectShow comes in to handy. It synchronizes and unifies all the communication flow between our application and the underlying hardware. In particular DirectShow talks directly with the camera drivers, capture card drivers etc… and provide feedback for the user application. This is the simplest way we can understand it, but for more details go here http://msdn.microsoft.com/en-us/library/windows/desktop/dd375454(v=vs.85).aspx .
