Interface BuildVolumeStreamlinesOptions

Integrate forward and backward from each seed. Default true.

Colormap used when colouring by speed. Default viridis.

Colour mode for the lines:

• "speed" — per-vertex colour from colormap at the normalised local speed.
• "uniform" — all lines use uniformColor.

Default "speed".

SceneModel id. Default "volumeStreamlines".

Pixel thickness of the streamline polylines. Forwarded to the renderer's thick-line draw technique via a per-mesh SceneMaterial.lineWidth override. Default 2. but not so chunky it occludes adjacent streamlines.

Set to 0 to fall back to the View's default linesMaterial.lineWidth.

Max integration steps per streamline. Caps both compute and resulting mesh size. Default 200.

Speed below which the integrator stops. Default 1e-4 (in whatever units the field carries).

Magnitude range mapped to the colormap. Default grid.magnitudeRange or the data-driven min/max.

Seeds are laid out in a seedDensity³-ish regular lattice inside the volume bbox. Default 6 → about 216 streamlines, which fits inside the WebGL line-batch limit at typical step counts. Increase for more seed coverage at the cost of mesh size.

Per-streamline integration step in world units. Default = half of the smallest voxel spacing. Smaller is finer and more expensive.

Solid colour used when colorMode === "uniform". Default [0.10, 0.50, 0.90].
