ANGLE- DEPENDENT ANISOTROPIC FILTERING |
| 摘要 |
A method for anisotropic filtering is provided herein. The method includes computing an anisotropic filter with a major-axis and a minor-axis for a pixel to be displayed on screen-space, wherein the anisotropic filter is to be applied to corresponding MIPs on a texture map. The method includes varying the length of the major-axis of the anisotropic filter based on the angle of the major-axis of anisotropy with respect to the screen space. The method includes determining a number of texels from the texture map that are to be sampled in the anisotropic filter based on the length of the modified major-axis. The method includes determining the color of the pixel based on the texels sampled in the anisotropic filter. |

1. A method for angle dependent anisotropic filtering, comprising:
computing an anisotropic filter with a major-axis and a minor-axis of a texture map for a pixel to be displayed on screen-space; modifying the length of a major-axis of the anisotropic filter based on a screen space angle; determining a number of texels from the texture map that are to be sampled in the anisotropic filter based on the length of the modified major-axis; and determining a color of the pixel based on the texels sampled in the anisotropic filter. |
