Abstract: A method for style guide management is described. A first user input is received from a user via a graphical user interface (GUI). The first user input identifies a writing sample having a textual style. A style guide is generated, based on the writing sample, having a description of a target style, based on the textual style, for input to a generative neural network model (GNNM). A profile representing the style guide and comprising a natural language format description is sent for display in the GUI. The style guide is modified based on an explicit indication of a style preference. A request for drafting assistance is sent to the GNNM, the request including the style guide for text generation according to the style guide by the GNNM. An output generated by the GNNM in response to the request is obtained. The output is sent to be displayed within the GUI.

Abstract: Technologies are provided for generation of an executable package that provides a tenant-specific service. Generation of the executable package can be based on customization assets and a core codebase. The core codebase can define core modules that provide a core service that is common across tenants. Each core module includes one or multiple extension points. The customizations can be defined within one or multiple virtual partitions, where a virtual partition includes a filesystem or another type of non-transitory storage structure. The VP can include multiple customization resources and customization components. The customizations can permit building extension modules that can be mapped onto respective extension points of core module(s) in order to customize the common core service and yield the tenant-specific service. The core codebase can be built to generate built core modules. The executable package can be formed by combining built extension modules and built core modules.

The method comprises capturing a plurality of multi-plane images of a virtual scene, and determining for each multi-plane image, whether a frontmost clipping plane pair defined for that multi-plane image intersects a virtual object in the virtual scene.

Camera information is obtained for the one or more virtual cameras that captured the multi-plane images and the target virtual camera. An output image is then generated by combining at least one of the modified multi-plane images with another of the multi-plane images in accordance with the obtained camera information. A corresponding system is also provided.
