ABSTRACT:
Systems and methods provide a more efficient and effective gradient computation. Specifically, in one embodiment, a method is provided for calculating a texture-mapping gradient, which comprises calculating constant values for use in a gradient-calculating equation, passing the constant values to logic configured to calculate the gradient, and computing the gradient using barycentric coordinates and the calculated constant values. In accordance with another embodiment, an apparatus is provided for calculating a texture-mapping gradient, which comprises logic for calculating constant values for use in a gradient-calculating equation, and logic for computing the gradient-calculating equation using barycentric coordinates and the calculated constant values. In accordance with another embodiment, a computer-readable medium is also provided that contains code (e.g., RTL logic) for generating the computational logic mentioned above.
