1. Precise Pixel Interpolation PPI PPI contributes to the HyperPipelined 3D quality with Intel s unique texture engine that deliv ers precise accuracy in interpolation operations of pixel values and color values This detailed pixel processing maintains a high level of image quality in every scene Shading Flat darkening or lightening the intensity of a polygon based on the angle between its normal and a vector pointing to a light source All pixels on a polygon receive the same adjustment resulting in a faceted appearance The per polygon and per pixel cal culation load is very light Shading Gouraud darkening or lighting each pixel of a polygon based on an interpolation between values calculated at the polygon s vertices A vertex normal is prescribed or inferred and the intensity at that vertex is determined by the angle between that normal and a vector pointing to a light source Each pixel is interpolated separately producing a simulation of a curved surface Gouraud shading makes objects appear to have a matte finish with no specular components The per polygon and per pixel calculation load is moderate Z Buffer a buffer memory that holds the Z depth information per pixel The Z axis is perpendicular to the X and Y axis of the screen and in most practical cases inverse range is uded due to the fact that it is linear in screen space where range is not Compares in depth between pixels of two polygons can be
