ABSTRACT:
Methods and apparatus, including computer program products, implementing and using techniques for generating a composite image from both two-dimensional (2D) image layers and three-dimensional (3D) image layers. In one embodiment, the image layers are arranged in a sequence in which a top 3D image layer is separated from a bottom 3D image layer by a 2D image layer and the image layers are rendered according to the sequence. In another embodiment, at least one of the image layers is associated with an adjustment layer, and rendering the composite image includes determining whether each current image layer has an associated adjustment layer with a dimensionality different from that of the current image layer, and if it does, applying the adjustment layer accordingly. In another embodiment, at least one of the image layers is associated with a track matte.
