How to create a numpy array of a UniformBufferObject that is read in by GLSL layout binding?

[sunbearc22]

I am trying to set up a UniformBufferObject per this tutorial that is supposed to be read in by GLSL via Layout binding.

May I know what is the numpy equivalent of the below struct?

struct UniformBufferObject {
    glm::mat4 model;
    glm::mat4 view;
    glm::mat4 proj;
};

Example, after creating the transformation matrices model, view, and proj like so, what should I do next to convert it to a numpy array(equivalent to struct UniformBufferObject ) that could then be passed to GLSL layout binding?

>>> model = [0.1, 0.1, 0.1, 1, 0.1, 0.1, 0.1, 1, 0.1, 0.1, 0.1, 1, 0.1, 0.1, 0.1, 0,]
>>> view = [0.2, 0.2, 0.2, 1, 0.2, 0.2, 0.2, 1, 0.2, 0.2, 0.2, 1, 0.2, 0.2, 0.2, 0,]
>>> proj = [0.3, 0.3, 0.3, 1, 0.3, 0.3, 0.3, 1, 0.3, 0.3, 0.3, 1, 0.3, 0.3, 0.3, 0,]
>>> modeln = np.asarray(model, dtype= 'f4').reshape(4,4)
>>> viewn = np.asarray(view, dtype= 'f4').reshape(4,4)
>>> projn = np.asarray(proj, dtype= 'f4').reshape(4,4)
>>> modeln
array([[0.1, 0.1, 0.1, 1. ],
       [0.1, 0.1, 0.1, 1. ],
       [0.1, 0.1, 0.1, 1. ],
       [0.1, 0.1, 0.1, 0. ]], dtype=float32)
>>> viewn
array([[0.2, 0.2, 0.2, 1. ],
       [0.2, 0.2, 0.2, 1. ],
       [0.2, 0.2, 0.2, 1. ],
       [0.2, 0.2, 0.2, 0. ]], dtype=float32)
>>> projn
array([[0.3, 0.3, 0.3, 1. ],
       [0.3, 0.3, 0.3, 1. ],
       [0.3, 0.3, 0.3, 1. ],
       [0.3, 0.3, 0.3, 0. ]], dtype=float32)

I could not relate uniform.py with this tutorial UniformBufferObject. Appreciate your guidance. Cheers.
