`
`FIELD OF THE INVENTION
`
`The present invention relates generally to graphics pro-
`cessors and, more particularly, to a transform module of a
`graphics pipeline system.
`
`BACKGROUND OF THE INVENTION
`
`Prior Art FIG. 1 illustrates a general prior art system that
`implements a pipelined graphics processing system. In this
`system, data source 10 generates a stream of expanded
`vertices defining primitives. These vertices are passed, one
`at a time, through pipelined graphic system 12 via vertex
`memory 13 for storage purposes. Once the expanded verti-
`ces are received from the vertex memory 13 into the
`pipelined graphic system 12, the vertices are transformed
`and lit by a transformation module 14 and a lighting module
`16, respectively, and further clipped and set-up for being
`rendered by a rasterizer 18, thus generating rendered primi-
`tives that are then displayed on display device 20.
`During operation, the transform module 14 may be used
`for receiving vertices in model coordinates and transforming
`the three dimensional vertices from their model coordinates
`
`to the two dimensional window where they will ultimately
`be displayed. In order to achieve the transformation, stan-
`dard transform parameters may be employed such as a view
`port, a viewing matrix, a world matrix, a projection matrix
`and so forth.
`
`Together, the foregoing parameters allow geometric trans-
`formations to express the location of an object relative to

`
`another object, rotate, clip and size various objects, as well
`as change viewing positions, directions, and perspectives in
`the three dimensional scene. Coordinate transformations that
`transform the three dimensional vertices from their model
`
`coordinates to the two dimensional window where they will
`be displayed typically involve one or more of translation,
`rotation and scaling.
`Prior art transform systems typically handle scalar and
`vector values that are generated during the transform process
`separately. For example, a position attribute, i.e. Oi, Y, Z,
`W), may be processed via a vector operator such as multi-
`plier and/or an adder, thus rendering a scalar value. While a
`scalar operator may process such scalar value, it is typically
`not processed again by the vector operator. Until now there
`have been no attempts to integrate the processing of scalar
`and vector forms of processed vertex data during graphics
`pipeline processing.
`Yet another process handled by the transform module 14
`is blending, or “skinning.” Skinning refers to the process of
`adding realism to segmented polygonal objects by blending
`a joint between the objects. Prior Art FIG. 1A illustrates a
`pair of objects 22 before and after skinning is performed.
`Conventionally, the skinning process is carried out using
`a computer program and a general-
