Transformation operation on an object rendered using a distancefield tracer.
The reddish rod in the middle is the base object. Using this as base, a non-linear transformation is applied, producing the green object.
Since this will distort the distancefield, a bound on the change of the transformation can be used to still get correct results. For this, I didn’t calculate the bounds directly. Instead I used optimization to find bounds on the norm of the jacobian (generated by automatic differentiation) for a simple hierarchical region.
Works alright ^^
