matlab - Plot normal vector field 3D -


i implementing algorithm photometric stereo have calculated normals set of images different light directions.

how can plot normal vector field in matlab? have matrix of normals of size (n x 3).

i'm afraid have left out step. need retrieve depth map surface normals, , can start plotting. see how this, can check out section 4 of following paper:

http://www.wisdom.weizmann.ac.il/~vision/photostereo/photometric%20stereo%20with%20general%20unknown%20lighting%20-%20basrijacobskemelmacher_ijcv06.pdf

there other resources on web too; don't know of built-in function in matlab library, don't have computer vision toolbox, knows?
