The present invention discloses a dynamic rendering method and device based on implicit light transfer function, comprising the following steps: step 1, inserting an object into an original three-dimensional scene to form a new three-dimensional scene, using a new three-dimensional scene, a camera position, and an observation direction as input samples, and using the difference between the true value of the rendering result of the original three-dimensional scene and the true value of the rendering result of the new three-dimensional scene as a first sample label to form a first class of sample data; supervised learning of a neural network by using the first class of sample data, using a neural network with optimizable parameters as the implicit light transfer function; step 2, taking the new three-dimensional scene, the camera position, and the observation direction as input variables of the implicit light transfer function, obtaining a radiance change field of the new three-dimensional scene through the calculating of the implicit light transfer function, and merging the radiance change field into the rendering result of the original three-dimensional scene to obtain the rendering result of the new three-dimensional scene, suitable for dynamic rendering of various three-dimensional scenes.
