There was a great post about how to create a Blender camera from a 3x4 computer vision matrix: blender camera from 3x4 matrix
How do you combine this projection matrix with an already existing camera in Blender?
For example, I want to keep the location/orientation in the blender scene and just slightly modify the camera with the location/rotation from the P matrix? I want to specify the camera center and orientation in standard computer vision coordinate system (X is right, Y is down, Z is into the screen) and then transform it relative to the already existing camera.
A use case for this would be to create a stereo camera in blender for some existing scene.
