PreonLab 1.3 comes with an enriched and optimized feature-set for pre- and post-processing. The improved camera and the extended clipping objects make navigating in the 3d scene much easier. Pre-processing is simplified by resource objects which can hold animations provided in vda file format or manage multiple meshes stored in one file. Furthermore, an alternative sampling method is introduced which is independent of the triangle mesh structure. This prevents leakage for high-poly meshes. Post-processing capabilities are extended by motion-aware pathlines as well as the Preon renderer which now supports wetting and force sensors.

Setting up a scene with PreonLab is now even simpler. Files that hold multiple geometry parts can be just drag’n’dropped. PreonLab automatically creates a resource object and distinct objects for every geometry part. All parts can be scaled with a single click by changing the unit property of the resource object. All sub-parts can be managed and deleted independently. PreonLab 1.3 also provides an alternative sampling method which is independent of the triangle mesh structure. Along with mesh resources, PreonLab 1.3 now supports animations in the vdafs format which can be applied to any geometry or transform group.
Pathlines are a powerful tool to gain insight about the trajectory of the fluid flow, particularly when the fluid is undesirably wetting certain geometries. Sometimes the trajectories are only meaningful if they are relative to the motion of these geometries, e.g., a moving car in a wading simulation. With PreonLab 1.3 you can generate pathlines that are relative to any pre-defined motion by simply using the transform slot of the PreonLab connection system.
Camera usage is now more intuitive. Orthographic cameras can be transformed just like perspective cameras. Animating a camera path is easier and works well with transform parents. In PreonLab 1.3, clipping is more powerful, besides the infinite clipping plane, finite clipping volumes can be used to clip the inside or outside of a box-shaped region. As multiple clipping objects can be combined, any region of interest can be uncovered comfortably. The Preon renderer supports the new clipping objects as well as the wetting and force sensor.
Finite clipping object uncovers the water flow in the engine compartment. Only irrelevant geometry parts are clipped. Wetted surfaces are highlighted with red.
