Abstract:
1. A method of computing an optimized level of detail value for texture map filtering, comprising: receiving a level of detail value for a texture map; applying a bias to the level of detail value to produce a biased level of detail value, including a integer portion and a fractional portion; selecting a modified fractional portion from a look-up table based on the fractional portion, wherein the modified fractional portion has a value of zero, if the fractional portion is between zero and a first non-zero value, the modified fractional portion has a value between zero and one, if the fractional portion is within a transition band defined between the first non-zero value and a second non-zero value, and the modified fractional portion has a value of one, if the fractional portion is greater than the second non-zero value; and combining the modified fractional portion with the integer portion to produce the optimized level of detail value.
