See through the scalar field.

A float Data3DTexture feeds the official-style VolumeRenderShader1 raycaster. MIP and isosurface modes share one volume while clim, threshold, and colormap controls change the interpretation.

Creating a procedural float scalar field…

This route covers native WebGL2 float Data3DTexture ownership, sampler3D volume rendering, MIP/ISO style selection, clim/threshold/colormap uniforms, camera interaction, and teardown. It does not claim the official NRRD stent asset, exact dimensions/pixels, GUI/Stats presentation, device format matrix, or whole-example fidelity.

The procedural field is deterministic and replaces the official NRRD payload only for this scoped contract.
