APPARATUS, METHOD, AND COMPUTER-READABLE MEDIUM FOR IMAGE PROCESSING USING VARIABLE-PRECISION SHADING - A simplified explanation of the abstract
- This abstract for appeared for patent application number 17715807 Titled 'APPARATUS, METHOD, AND COMPUTER-READABLE MEDIUM FOR IMAGE PROCESSING USING VARIABLE-PRECISION SHADING'
Simplified Explanation
This abstract describes a method used in computer graphics to shade a group of pixels in a specific way. The process involves shading at least two pilot pixels in the group, each with a different level of precision. The difference between these pilot pixels is then calculated as an error value. Depending on this error value, the remaining pixels in the group are shaded either with the higher precision or the lower precision. This method helps optimize the shading process by selectively applying different levels of precision based on the error threshold.
Original Abstract Submitted
There is described a method of shading a group of pixels in a fragment shader in a raster graphics pipeline. At least one first pilot pixel of the group of pixels is shaded under a first precision. At least one second pilot pixel of the group of pixels is shaded under a second precision. An error value representing a difference between the first and second pilot pixels is calculated. At least one other pixel of the group of pixels is shaded under the first precision if the error value is greater than an error threshold. The at least one other pixel is shaded under the second precision if the error value is smaller than the error threshold.
