Rendering and searching for 3D objects

Hi everyone, I want to make 2D images by taking images from various angles of 3D objects with pytorch3d, that is, by rendering them, then I want to search for similarity with artificial intelligence support by extracting features from these images, for example, when I want to find a 3D object that exists in my database or when I want to check whether it exists, I can say that I want to search for it with an image that I will give as a parameter, but I am very new to this subject, can you help me with this?
