Computer-implemented methods and computer program apparatus, for implementing techniques for shading selected regions of an image. These include receiving an input selecting a region to be filled, receiving an input defining a gradient specifying a color transition to be applied between a starting position and an ending position, and applying the gradient between the starting position and the ending position to assign, based on the shape of the selected region, a color for each of a plurality of points located inside an outline defining the region's shape.

A method for generating a structured-light pattern is disclosed, wherein high-resolution real-time three-dimensional (3D) data can be obtained by using a single frame (or one-shot) imaging or double frames (or two-shot) imaging methods. The structured-light pattern for the one-shot imaging is formed of a multiple-stripe color pattern using a color selection scheme and a sequence principle. The proposed color selection scheme reduces the ambiguity in stripe labeling in one-shot imaging, and the proposed sequence principle increases the number of distinguishable stripe codes. The structured-light pattern for two-shot imaging is formed so that three-dimensional (3D) data can be obtained even for objects having strong surface colors with ambient lights, wherein the first two-shot pattern is synthesized, thereby forming a multiple-stripe color pattern using sign codes and a sequence principle under a condition that prevents color-transitions in more than one channels from occurring. Subsequently, the second two-shot pattern is formed by reversing the first two-shot pattern. Accordingly, high-resolution real-time three-dimensional (3D) data, which is insensitive to object shape and surface color, system noise and nonlinearity, can be obtained.

A system and method for temporally anti-aliasing a display of a set of frames rendered from scene information without significantly increasing an amount of processing power used in rendering the frames. In some embodiments of the invention, a view used to render the frames from the scene information may be modulated between renderings of successive frames. This modulation of the view may temporally blend pixel colors displayed in pixels at or near color transitions in the frames by causing the pixel colors of these pixels to fluctuate between frames, thereby reducing aliasing present at these transitions as the human eye observing the display of the frames innately averages the fluctuating pixel colors.
