Standing Wave Viewer v1.1.2 Release Notes / リリースノート
Standing Wave Viewer v1.1.2 focuses on improving the physical credibility of the simulation engine and stabilizing the 3D room framing in the viewer.
Highlights
Improved physical consistency in True Complex Field
Added mode-based energy weighting.
Axial modes use 1.0, tangential modes 0.5, and oblique modes 0.25.
This significantly reduces the excessive cancellation-heavy blue regions at higher frequencies and the unrealistically strong corner peaks at lower frequencies.
Refined 3D axis presentation
Numeric tick labels were removed, leaving only the X / Y / Z axis labels.
The 4-division grid is now maintained through a robust workaround that avoids unstable CubeAxesActor behavior in VTK.
This prioritizes stable visual framing, especially for room dimensions below 2.5 m where the default behavior was unreliable.
Practical impact
Simulation output now behaves more like real small-room acoustics.
True Complex Field visualizations are easier to read and less exaggerated.
The 3D room frame is cleaner and more stable, making spatial proportions easier to grasp at a glance.
Note
The 3D grid refinement in this release is based on an implementation-level workaround for PyVista / VTK behavior. Internally, it is a fairly technical solution, but from a product perspective the chosen direction is simple: remove distracting numeric ticks and preserve a stable 4-division grid.
