VARIABLE ACUITY RENDERING USING MULTISAMPLE ANTI-ALIASING

摘要

Embodiments are described for a method for using anti-aliasing hardware to generate a higher resolution image at the processing of a lower resolution image with anti-aliasing. A graphics image comprising allocating a buffer used in a multisample anti-aliasing process, wherein the allocated buffer has a dimension comprising a reduction in at least one of the width or height of an original dimension of an original buffer provided by the anti-aliasing hardware; rendering sampled image data to the allocated buffer at a sampling rate proportional to the reduction; and expanding the allocated buffer back to the dimension of the original buffer.

1. A method for rendering a graphics image, comprising:
allocating a buffer used in a multisample anti-aliasing process, wherein a size of the allocated buffer comprises a reduction in at least one of the width or height of a dimension of an original buffer; and rendering sampled image data to the allocated buffer at an increased sampling rate proportional to the reduction.
