isosurface

Extract an isosurface from a 3D scalar volume.

Syntax

[h] = isosurface(V, isoval)
[f, v] = isosurface(V, isoval)

Description

Computes the surface where V = isoval in a 3D scalar volume (marching-cubes algorithm) and renders it. With multiple outputs, returns the face/vertex data without drawing.

Example

isosurface(peaks_3d, 0.5)
