A virtual experience system provides dynamically interactive virtual characters in an environment. The system may be built in a modular fashion, enabling new behaviors and functionality to be added without significant alterations to the existing parts of the system. For example, behavior may be modeled using a model with multiple layers. Each layer determines responses to external stimuli based on one or more factors, with the behavior of a character being determined based on a combination of the layers of the model.

Computing an output image of a dynamic scene. A value of E is selected which is a parameter describing desired dynamic content of the scene in the output image. Using selected intrinsic camera parameters and a selected viewpoint, for individual pixels of the output image to be generated, the method computes a ray that goes from a virtual camera through the pixel into the dynamic scene. For individual ones of the rays, sample at least one point along the ray. For individual ones of the sampled points, a viewing direction being a direction of the corresponding ray, and E, query a machine learning model to produce colour and opacity values at the sampled point with the dynamic content of the scene as specified by E. For individual ones of the rays, apply a volume rendering method to the colour and opacity values computed along that ray, to produce a pixel value of the output image.

A virtual vehicle control method in a virtual scene, performed by a terminal, is provided. The method includes providing a display interface of an application program, the display interface including a scene picture of the virtual scene, and the virtual scene including a virtual vehicle; obtaining a moving speed of the virtual vehicle; and adjusting, based on the moving speed of the virtual vehicle being greater than a moving speed threshold, the scene picture to a picture of the virtual vehicle being observed in the virtual scene by using a camera model in a predetermined viewing angle direction, the camera model being located at a position with respect to the virtual vehicle.

Disclosed is a virtual character interaction method, including: displaying a viewing-only picture of a virtual character interaction scene; switching from the viewing-only picture to a virtual character simulation interaction interface in response to an interaction simulation operation triggered during displaying of the viewing-only picture; simulating, in the virtual character simulation interaction interface, virtual characters in the virtual character interaction scene, and displaying a scene status of interaction between the virtual characters, wherein the virtual characters include a simulated virtual character controlled by a user of the computer device; and controlling the simulated virtual character to perform a corresponding action in response to a control operation triggered on the virtual character simulation interaction interface by the user of the computer device.
