Add 3D content to an image using blender I have an image of a scene and I extracted the projection matrix from that, so I have the camera calibration. Now, I want to add some 3D objects to this scene. I have already coded something with OpenGL. You can see the results here (the white wall is added in OpenGL):



Now, I want to achieve the same thing with Blender, because it's easier to work with complex models and complex scenes. Can anyone give me any pointers on how to convert from OpenGL camera to Blender?
If you were using a video, you could use blender camera tracking, and add objects to the scene that way. Then, you could select the exact frame in the video that you wanted to add the objects to. For example, if you had a video of the soccer game, then you could use that.

Here is an tutorial on blender camera tracking:
