Abstract: Hardware acceleration of the rending and animation of characters that treat each pixel sub-component as a distinct luminance intensity source. A bit-map representation of the sub-component-oriented character is generated by using a single image sample to generate each pixel sub-component. This may be accomplished by, for example overscaling a representation of the character, placing the overscaled representation of the character on grid, and then assigning a luminance and possibly a transparency value to each grid position based on the property of the overscaled character at the grid position. The, the character is rendered by interfacing with a hardware graphic unit that perform the final rendering and animation of the character.

Abstract: Methods, systems, and computer readable media use closed contours of a modeled surface for various purposes such as displaying a contour map of the modeled surface or computing volumetrics. For the closed contours, a colorfilled contour map may be displayed where each contour level is represented as a shape that has an opaque fill color by calculating the area of each shape and displaying the shapes in decreasing order of area.

These closed contours may then be used for various purposes, such as calculating volumetrics of the modeled surface or generating the colorfilled contour map display according to the area of the closed contours.

Abstract: A method and apparatus are provided for dewarping images. According to one aspect of the present invention, rotational motion of a scene is taken into account for purposes for performing image dewarping. The image is extracted from the scene by selecting pixel values from an environment map that correspond to a viewing plane. Velocity information associated with rotational motion of the scene is determined. Then, based upon the velocity information, a velocity-dependent transformation is determined. Finally, a perspective image is created by applying the velocity-dependent transformation to the image. In this manner, when the images is presented to a user, the appearance of visible and objectionable distortion may be reduced while maintaining the perceived geometric accuracy of the image. For example, when the scene is rotating at a high angular velocity, little or no dewarping may be performed and the image extracted therefrom may be presented essentially uncorrected.
