Data validation consists of creating a loop between the ob- served surface and calculated results to expose errors immedi- ately. This is referred to as live processing state management.

In Qimera it is very easy to make processing con? guration adjustments or to perform data validation and to immedi- ately asses the impacts of changes. Near immediate feedback shortens the time between cause and effect while promoting causal reasoning which is a key ingredient for natural cog- nitive evolution. In short, it allows users to train themselves through something as simple as immediately recalculating the dynamic surface and showing the user they have accidentally deleted good data or applied the wrong SVP, etc (Fig 3).

This example shows a simple grid of nine subprojects.
