Thanks Phil for proposing this feature in Renovations 3D
I computed an image based on the example 11 of the gallery, and the rendering on a Samsung Galaxy Tab A6 1.6 GHz was 10 times slower than on an iMac 4 GHz, even if processors on both machines have 8 cores. But the good thing is that the rendering process didn't consume too much power on the tablet battery and the computed images are the same.
