Abstract
A method of computing z parameters for pixels of a geometric primitive. The method includes the step of accessing the geometric primitive comprising a plurality of vertices, wherein each vertex comprises a plurality of associated parameters including a depth parameter, z. During rasterization of the geometric primitive, respective z values are interpolated for each pixel of the geometric primitive. Each z value is represented within a predefined numerical range which substantially corresponds to a depth range between a near plane and a far plane related to pixel rendering. During the interpolating, the z values are allowed to exceed the predefined numerical range and roll over within the predefined numerical range. A multi-bit indicator is used to indicate when a z value for a pixel is outside of the depth range.
