Abstract: Implementations of the present disclosure involve methods and systems for creating depth and volume in a 2-D image by utilizing a plurality of layers of the 2-D image, where each layer comprises one or more portions of the 2-D image. Each layer may be reproduced into a corresponding left eye and right eye layers that include a depth pixel offset corresponding to a perceived depth. Further, a volume effect may also be applied to one or more objects of the 2-D image by associating a volume pixel offset to one or more pixels of the image. Thus, any pixel of the 2-D image may have a depth pixel offset to provide a perceived depth as well as a volume pixel offset to provide a stereoscopic 3-D volume effect. In this manner, the 2-D image may be converted to a corresponding stereoscopic 3-D image with perceived depth and volume effects applied.

Abstract: Objects are modeled and rendered using multiple surfaces to provide attributes used in rendering. In some embodiments, a reference surface for an object is defined, e.g., using conventional modeling techniques. One or more auxiliary surfaces are associated with portions of the reference surface. Some of the surface attributes (e.g., color, surface normal, texture, lighting) are associated with the reference surface, while other attributes (e.g., transparency) are associated with the cards. To render an image, a ray associated with a pixel is traced to its intersection with the reference surface and to its intersection with one of the auxiliary surfaces. The attributes associated with the reference surface are determined based on the intersection point of the ray with the reference surface, and the attributes associated with the auxiliary surface are determined based on the intersection point of the ray with the auxiliary surface.

Abstract: Shadows are rendered automatically with a hand-painted appearance. The shadow region is divided into a core and a penumbra. A core perturbation zone is defined between the core and penumbra and a penumbra perturbation zone is defined between the penumbra and an unshadowed region. Within each perturbation zone, a texture is applied to each pixel to map the pixel as being inside or outside the core or penumbra boundary, thereby defining a displaced core boundary and a displaced penumbra boundary. The displaced boundaries can be non-linear and discontinuous. When shadows are rendered using the displaced boundaries, a hand-painted appearance can result. An additional texture can be applied in the penumbra to further enhance the painted appearance.
