Abstract: Some implementations relate to methods, systems, and computer readable media for generating code based on three-dimensional (3D) virtual assets. A 3D model of a 3D virtual object is received. A latent representation of the 3D model is generated using a pre-trained encoder, and encodes semantic and structural information of the 3D model. A text prompt and the latent representation of the 3D model are provided as input to a code generation model, where the text prompt includes a request to generate code with references to the 3D virtual object and where the latent representation of the 3D model serves as a conditioning input to the code generation model. The code is generated by the code generation model upon execution on a virtual platform or a client device, and causes the virtual platform or client device to perform one or more actions with reference to the 3D virtual object.

Abstract: An environment is described which enables the generation, analysis, and use of secure browser extensions. Each browser extension includes an extension body and a policy expressed in a logic-based specification language. The policy specifies the access control and dataflow privileges associated with the extension body in a fine-grained manner by leveraging the structure and content of resources that are accessible to the browser extension. A suite of analysis tools for testing the safety of the browser extension includes a visualization module identifies features of a resource that are accessible to the policy. A static analysis module uses a static analysis technique to determine whether the extension body satisfies the policy. The environment also includes a conversion module for converting the browser extension, once deemed safe, into a form for use by a particular type of browser. The browser can execute that extension without performing runtime safety checks.
