摘要： An apparatus and method for compressing ray tracing data prior to transmission between nodes. For example, one embodiment of an apparatus comprises: a first node comprising a first ray tracing engine, the first node communicatively coupled to a second node comprising a second ray tracing engine; first compression circuitry coupled to the first ray tracing engine, the first compression circuitry to perform compression on ray tracing data of the first ray tracing engine to produce a first compressed stream of ray tracing data; and interface circuitry to transmit the first compressed stream of ray tracing data from the first node to the second node.

摘要： Various embodiments are generally directed to techniques for reducing processing demands of shading primitives in rendering a 2D screen image from a 3D model. A device includes a clipping component to clip a visible primitive of a 2D screen image derived from of a 3D model within a first area of the screen image covered by a shading pixel to form a polygon representing an intersection of the first area and the visible primitive; a first interpolation component to interpolate at least one attribute of vertices of the visible primitive to each vertex of the polygon; and a second interpolation component to interpolate color values of the vertices of the polygon to a point within a second area covered by a screen pixel of the screen image, the second area smaller than the first area and at least partly coinciding with the first area. Other embodiments are described and claimed.
