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.

The present invention discloses a cloud-client rendering computing method based on an adaptive virtualized rendering pipeline, comprising the following steps of: defining a rendering pipeline, including defining a rendering resource, a rendering algorithm, and a read-write relationship between the rendering algorithm and the rendering resource; selecting an optimal cloud-client computing distribution solution in a real-time manner from a cloud-client computing distribution solution set comprising each rendering resource that is allocated to a cloud or client for computing, based on self-defined optimization objectives and an optimization budget of a framework user; and executing a corresponding rendering algorithm on cloud and/or on a client according to the cloud-client computing distribution solution, thereby obtaining a rendering result. The rendering framework can adaptively select the cloud-client computing distribution solution upon cloud-client combined rendering and dynamically adjust it with a change of an optimization parameter.
