TemporalAntiAliasingOptions

open class TemporalAntiAliasingOptions

Options for Temporal Anti-aliasing (TAA) Most TAA parameters are extremely costly to change, as they will trigger the TAA post-process shaders to be recompiled. These options should be changed or set during initialization. filterWidth, feedback and jitterPattern, however, can be changed at any time.

feedback of 0.1 effectively accumulates a maximum of 19 samples in steady state. see "A Survey of Temporal Antialiasing Techniques" by Lei Yang and all for more information.
