Abstract
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.
