Display

  • Show Grid: Show or hide the reference grid.
  • Mesh: Switch the bounding box display mode between outline, box, and hidden.

Arrows

  • Mode
    • all: Sample arrows throughout the full 3D volume.
    • layer: Show arrows only on one selected slice layer.
  • Direction: Select the layer direction in layer mode. Supported directions are x, y, and z.
  • Index: Select the layer index in layer mode. The range is updated automatically from the data dimensions.
  • Nx / Ny / Nz: Control the arrow sampling density.
  • Size: Control the arrow size.
  • Component: Color arrows by the mx, my, or mz component.
  • Colormap: Select the arrow colormap.

Slice

  • Direction: Select the slice direction.
  • Index: Select the slice layer index.
  • Component
    • all-components: Use HSV color for the in-plane magnetization direction, with black/white shading from mz.
    • mx / my / mz: Show a single magnetization component.
  • Colormap: Select the slice colormap.

Isosurface

  • Show: Enable or disable the isosurface.
  • Component: Generate the isosurface from mx, my, or mz.
  • Value: Set the isosurface value.
  • Resolution: Set the Marching Cubes resolution. Higher values produce finer surfaces but take longer to compute.
