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.
