Query: Direct interactive visualization of locally refined spline volumes for
  scalar and vector fields   We present a novel approach enabling interactive visualization of volumetric
Locally Refined B-splines (LR-splines). To this end we propose a highly
efficient algorithm for direct visualization of scalar and vector fields given
by an LR-spline. In both cases, our main contribution to achieve interactive
frame rates is an acceleration structure for fast element look-up and a change
of basis for efficient evaluation. To further improve the efficiency, we
present a heuristic for adaptive sampling distance for the numerical
integration. A comparison with existing adaptive approaches is performed. The
algorithms are designed to fully utilize modern graphics processing unit (GPU)
capabilities. Important applications where LR-spline volumes emerge are given
for instance by approximation of large-scale simulation and sensor data, and
Isogeometric Analysis (IGA). We showcase interactive rendering achieved by our
approach on different representative use cases, stemming from simulations of
wind flow around a telescope, Magnetic Resonance (MR) imaging of a human brain,
and simulations of a fluidized bed used for mixing and coating particles in
industrial processes.
