I have accomplished the core of my vision for the qemical flood technology. A reconstruction of arbitrary smooth surfaces from control points in real time. I wasn't able to quickly eradicate 100% of precision errors in 32 bit float precision, but it is pristine in 64. So at least the algorithm itself is fine and precision enhancement will have to be an ongoing effort together with performance optimization — I certainly have ideas for both — as I finally move onto proper sculpting.
