Augmented Reality - Rendering 3D objects using projection matrix

I have a calibration method that extracts from a static scene the projection matrix P = K[R | t] of the scene (where Z is the height and Z=0 is the ground plane).

My question is what the easiest way to plot a 3D object in this scene using the projection matrix P? A few years ago I made a similar code that used OSG to plot the object (however in that case I had estimates of the intrinsic and extrinsic parameters separately).

Do you guys know how to render the 3D in this case?

Define "easiest"? In opengl you can just set you projection matrix as the modelview, and start drawing. Caveats, the usual ones: make sure your viewport / clipping planes make sense.
