Abstract: A coverage based approach to image rendering using opacity values is described. In one embodiment, a digital medium environment is configured to render an image. A plurality of layers of the image are rendered in succession as following a defined depth ordering for the plurality of the layers. Effective coverage and color is determined of a plurality of objects, together, for pixels within respective ones of the plurality of layers of the image. Contribution is then controlled of the determined coverage and color of the objects to opacity values and color values in a buffer for respective pixels. This control is based on whether the opacity values indicate that the respective pixels are opaque.

Abstract: Systems and methods for dynamic integration of advertisements in 3D virtual environments may provide contextual placement of advertising assets into those environments. The advertising assets may include 3D models of products or advertisements. The selection of appropriate advertising assets during runtime may be dependent on context-sensitive metadata associated with placeholders tagged in the virtual environment by a virtual environment authoring application, and corresponding metadata associated with available advertising assets. The metadata may include classification attributes, visual attributes, physical attributes, behavioral attributes, or interactivity attributes. The selection of appropriate advertising assets may be further dependent on user information and/or game session information captured at runtime. Additional advertising assets may be dynamically selected in response to interactions with the advertising assets, or dependent on changes in status of a user or game session.
