Interpolants

This simple WebGL application shows the isosurface for different voxel configurations using trilinear and tricubic funcions. If you cannot see a WebGL app, go to this page.

Orange dots correspond to scalar values greater than the value of the isosurface of interest, whereas white dots correspond to lower scalar values. The button Apply changes the isovalue of interest and Randomize assigns random values to the 27 vertices of the 3x3x3 voxels (only the voxel at the center in shown).
