 ===== Adaptive Sampling =====

-If a good configuration of the base sampling has been found, the the resulting quality of that can be controlled by the Camera (AA) sampling, which also can be done adaptive based on actual geometric/feature demands at that part of the image. Using adaptive sampling with an idencal high Max.-value will speed up the rendering time with close to the same quality. The following render times are in m.s and from different workstations of a farm, but nonetheless is quite obvious, that rendering with a sampling starting at 4 and ending at 20 (AA) is much faster that having static value all along (see. first row of table below).

 ===== Sampling Saturation =====

 The image above shows a noticeable horizontal line starting around image ~10, which indicates that there is no further gain in image quality by just raising the sampling settings, on which basis a denoising will be applied. This is explicitly true for the **adaptive sampling**.
+==== Questions ====
+  * Does the **Adaptive Threshold**-Property apply a higher sampling binary (yes/no) or is there a smooth transition later between regions of higher and lower sampling?  --- //[[r.engel@mediadesign.de|Rainer M. Engel]] 2024/01/23 18:12//
