| Parameter | Description |
|---|---|
| X, Y, Z | Grid vectors or 3-D grid arrays matching V. |
| V | Real numeric 3-D volume data. |
| vertices, p | N-by-3 vertex matrix or patch handle. |
| Parameter | Description |
|---|---|
| n | N-by-3 normal vectors interpolated from the volume gradient. |
isonormals computes normals at isosurface vertices. With a patch handle and no output, the VertexNormals property is set.
