Techniques for improving MSAA rendering efficiency

摘要

Various embodiments are generally directed to techniques for causing the storage of a color data value of a clear color to be deferred as rendered color data values are stored for samples. A device comprises a processor circuit and a storage to store instructions that cause the processor circuit to render a pixel from multiple samples taken of a three-dimensional model of an object, the pixel corresponding to a pixel sample data which comprises multiple color storage locations that are each identified by a numeric identifier, and which comprises multiple sample color indices that each correspond to a sample to point to at least one color storage location; and allocate color storage locations in an order selected to define a subset of possible combinations of binary index values among all of the sample color indices as invalid combinations. Other embodiments are described and claimed.

1. A device comprising:
a processor circuit; and a storage communicatively coupled to the processor circuit to store instructions that when executed by the processor circuit cause the processor circuit to:
render a pixel from multiple samples taken of a three-dimensional model of an object, the pixel corresponding to a pixel sample data, the pixel sample data comprising multiple color storage locations that are each identified by a numeric identifier, and the pixel sample data comprising multiple sample color indices that each correspond to a sample of the multiple samples to point to at least one color storage location of the multiple color storage locations;allocate color storage locations of the multiple color storage locations in an order selected to define a subset of possible combinations of binary index values among all of the sample color indices as invalid combinations; andinitialize the multiple sample color indices with binary index values that create a first invalid combination of binary index values among all of the sample color indices that indicates the pixel sample data is initialized to an uncolored state.
