Algorithm (Workflow)

Input Parameters

gh: This is an axis handle. If not provided, the default is the current axis, obtained using gca.

Output Results

h: A handle to all surface objects found within the specified graphics handle.

VL: A list of vertices for the surfaces.

FL: A triangulated facet list of the surfaces, generated using the surf2patch function.

Algorithm Steps

  1. Initialize gh to the current axis using gca.
  2. Check if there is at least one input argument and if it is not empty. If so, set gh to the provided argument.
  3. Use findall to find all objects of type 'surface' within the specified graphics handle gh. Assign these objects to h.
  4. If more than one output is requested, call the function VLFLofSurf with h to obtain the vertex list VL and the facet list FL.
