Apparatus, software and method for displaying line-formatted materials in multiple columns of a screen display and providing for scrolling through the materials such that lines spill from one column to another, are disclosed. The columns form a display area for display of contiguous lines of the line-formatted materials, wherein diagonally opposite ends of the rightmost and leftmost columns define the starting and ending lines of the display area, such that when scrolling through line-formatted materials the lines flow into and out of the display area at the starting and ending lines. In another embodiment, Scripting language encoded line-formatted materials are displayed under the control of a web browser using the scrollable columns. In another embodiment, line-formatted materials are encoded with one or more Scripting language codes that specify to a web browser that the line-formatted materials are to be displayed in scrollable columns.

A method is disclosed for determining whether a distant 3-dimensional object is completely obstructed from view by a closer 3-dimensional object. The method includes determining which of the two 3-dimensional objects is farther from a viewer. For the object farther away, determining that object's smallest bounding sphere, and projecting that sphere onto the view plane of the observer. For the object closer to the observer, determining that object's largest bounded sphere, and projecting that sphere onto the view plane. The two projections are then compared. If the near-object projection completely contains the far-object projection, then the distant object is completely obscured from view by the closer object. If completely obscured from view, the distant object is discarded; otherwise, the distant object is rendered in the normal manner.

A computer-implemented method and system for browsing encoded images. According to a preferred embodiment, at least one image is encoded with an encoding system to provide at least one encoded image. The encoding includes transforming images of the at least one image in accordance with a transform to provide a plurality of transform coefficients. A subset of the plurality of transform coefficients corresponding to a selected image is transmitted to a remote computer system, wherein the subset of the plurality of transform coefficients corresponds to a low quality version of the selected image.

A pixel interpolation system provides for continuous scaling of an image, thus allowing for continuous modification of the size and aspect ratio of the image. A one-dimensional interpolator provides a weighted interpolation between two input pixels using a specified current interpolation weight. The weighting factor is then incrementally changed and further interpolations are sequentially performed across at least one dimension of the image. With one implementation of the system, the scaling across the image remains uniform while the weight varies from one pixel to the next to keep scaling constant. The interpolation operation of this invention may be performed simultaneously both vertically and horizontally.

A method and apparatus for translating a first address in a first address space, such as a processor address space, to a second address in a second address space, such as a system address space, are described. Data alignment signal determinations based on comparisons between destination and source addresses permit automatic replacement of virtual addresses with actual physical addresses to permit direct data transfer between devices. In one embodiment, the apparatus for translating comprises a processor; a page table having a mask register, a comparison value register, and a replacement value register; and a comparator coupled to the comparison value register and to the replacement value register. A programmable mask within the translation mask register is employed to partition a virtual address. A first subaddress comprises a subset of the bits of the first address and a second subaddress comprises remaining bits of the first address. The first subaddress is masked with a programmable mask value in the translation mask register and is compared by the comparator with successive comparison values in the comparison value register until a match comparison value is found. A programmable replacement value in the replacement value register corresponding to the match comparison value is concatenated with the second subaddress. The programmable replacement values, which correspond to programable map windows, permit the programmable mapping of virtual addresses into different predetermined regions of system virtual address space.

A method for performing scaling of a video image uses a noninteger scale factor. The scaling using a series of images scaled according to integer powers of two. An integer scale factor is applied to the image to be scaled in order to provide a series of scaled images. A determination is made which scaled image is the closest image to the one corresponding to the fractional scale factor. The scaled image selected in this manner is then operated upon using an interpolation to obtain the value corresponding to the fractional scale factor. Alternatively, the two scaled images which are closest to the image corresponding to the fractional scale factor may be selected and an interpolation operation or an averaging operation of the two scaled images may be performed to obtain the factional scale image. The scaled images may be predetermined during off-line operations so that a plurality of image selections may be performed upon the same set of predetermined scaled images.
